Chapter 1. Release notes

1.1. Logging 5.8

Note

Logging is provided as an installable component, with a distinct release cycle from the core OpenShift Container Platform. The Red Hat OpenShift Container Platform Life Cycle Policy outlines release compatibility.

Note

The stable channel only provides updates to the most recent release of logging. To continue receiving updates for prior releases, you must change your subscription channel to stable-x.y, where x.y represents the major and minor version of logging you have installed. For example, stable-5.7.

1.1.1. Logging 5.8.15

This release includes RHBA-2024:10052 and RHBA-2024:10053.

1.1.1.1. Bug fixes

  • Before this update, Loki did not correctly load some configurations, which caused issues when using Alibaba Cloud or IBM Cloud object storage. This update fixes the configuration-loading code in Loki, resolving the issue. (LOG-6294)
  • Before this update, upgrades to version 6.0 failed with errors if a Log File Metric Exporter instance was present. This update fixes the issue, enabling upgrades to proceed smoothly without errors. (LOG-6328)

1.1.1.2. CVEs

1.1.2. Logging 5.8.14

This release includes OpenShift Logging Bug Fix Release 5.8.14 and OpenShift Logging Bug Fix Release 5.8.14.

1.1.2.1. Bug fixes

  • Before this update, it was possible to set the .containerLimit.maxRecordsPerSecond parameter in the ClusterLogForwarder custom resource to 0, which could lead to an exception during Vector’s startup. With this update, the configuration is validated before being applied, and any invalid values (less than or equal to zero) are rejected. (LOG-4671)
  • Before this update, the Loki Operator did not automatically add the default namespace label to all its alerting rules, which caused Alertmanager instance for user-defined projects to skip routing such alerts. With this update, all alerting and recording rules have the namespace label and Alertmanager now routes these alerts correctly. (LOG-6182)
  • Before this update, the LokiStack ruler component view was not properly initialized, which caused the invalid field error when the ruler component was disabled. With this update, the issue is resolved by the component view being initialized with an empty value. (LOG-6184)

1.1.2.2. CVEs

1.1.3. Logging 5.8.13

This release includes OpenShift Logging Bug Fix Release 5.8.13 and OpenShift Logging Bug Fix Release 5.8.13.

1.1.3.1. Bug fixes

  • Before this update, the clusterlogforwarder.spec.outputs.http.timeout parameter was not applied to the Fluentd configuration when Fluentd was used as the collector type, causing HTTP timeouts to be misconfigured. With this update, the clusterlogforwarder.spec.outputs.http.timeout parameter is now correctly applied, ensuring that Fluentd honors the specified timeout and handles HTTP connections according to the user’s configuration. (LOG-5210)
  • Before this update, the Elasticsearch Operator did not issue an alert to inform users about the upcoming removal, leaving existing installations unsupported without notice. With this update, the Elasticsearch Operator will trigger a continuous alert on OpenShift Container Platform version 4.16 and later, notifying users of its removal from the catalog in November 2025. (LOG-5966)
  • Before this update, the Red Hat OpenShift Logging Operator was unavailable on OpenShift Container Platform version 4.16 and later, preventing Telco customers from completing their certifications for the upcoming Logging 6.0 release. With this update, the Red Hat OpenShift Logging Operator is now available on OpenShift Container Platform versions 4.16 and 4.17, resolving the issue. (LOG-6103)
  • Before this update, the Elasticsearch Operator was not available in the OpenShift Container Platform versions 4.17 and 4.18, preventing the installation of ServiceMesh, Kiali, and Distributed Tracing. With this update, the Elasticsearch Operator properties have been expanded for OpenShift Container Platform versions 4.17 and 4.18, resolving the issue and allowing ServiceMesh, Kiali, and Distributed Tracing operators to install their stacks. (LOG-6134)

1.1.3.2. CVEs

Note

1.1.4. Logging 5.8.12

This release includes OpenShift Logging Bug Fix Release 5.8.12 and OpenShift Logging Bug Fix Release 5.8.12.

1.1.4.1. Bug fixes

  • Before this update, the collector used internal buffering with the drop_newest setting to reduce high memory usage, which caused significant log loss. With this update, the collector goes back to its default behavior, where sink<>.buffer is not customized. (LOG-6026)

1.1.4.2. CVEs

1.1.5. Logging 5.8.11

This release includes OpenShift Logging Bug Fix Release 5.8.11 and OpenShift Logging Bug Fix Release 5.8.11.

1.1.5.1. Bug fixes

  • Before this update, the TLS section was added without verifying the broker URL schema, leading to SSL connection errors if the URLs did not start with tls. With this update, the TLS section is added only if broker URLs start with tls, preventing SSL connection errors. (LOG-5139)
  • Before this update, the Loki Operator did not trigger alerts when it dropped log events due to validation failures. With this update, the Loki Operator includes a new alert definition that triggers an alert if Loki drops log events due to validation failures. (LOG-5896)
  • Before this update, the 4.16 GA catalog did not include Elasticsearch Operator 5.8, preventing the installation of products like Service Mesh, Kiali, and Tracing. With this update, Elasticsearch Operator 5.8 is now available on 4.16, resolving the issue and providing support for Elasticsearch storage for these products only. (LOG-5911)
  • Before this update, duplicate conditions in the LokiStack resource status led to invalid metrics from the Loki Operator. With this update, the Operator removes duplicate conditions from the status. (LOG-5857)
  • Before this update, the Loki Operator overwrote user annotations on the LokiStack Route resource, causing customizations to drop. With this update, the Loki Operator no longer overwrites Route annotations, fixing the issue. (LOG-5946)

1.1.5.2. CVEs

1.1.6. Logging 5.8.10

This release includes OpenShift Logging Bug Fix Release 5.8.10 and OpenShift Logging Bug Fix Release 5.8.10.

1.1.6.1. Known issues

  • Before this update, when enabling retention, the Loki Operator produced an invalid configuration. As a result, Loki did not start properly. With this update, Loki pods can set retention. (LOG-5821)

1.1.6.2. Bug fixes

  • Before this update, the ClusterLogForwarder introduced an extra space in the message payload that did not follow the RFC3164 specification. With this update, the extra space has been removed, fixing the issue. (LOG-5647)

1.1.6.3. CVEs

1.1.7. Logging 5.8.9

This release includes OpenShift Logging Bug Fix Release 5.8.9 and OpenShift Logging Bug Fix Release 5.8.9.

1.1.7.1. Bug fixes

  • Before this update, an issue prevented selecting pods that no longer existed, even if they had generated logs. With this update, this issue has been fixed, allowing selection of such pods. (LOG-5698)
  • Before this update, LokiStack was missing a route for the Volume API, which caused the following error: 404 not found. With this update, LokiStack exposes the Volume API, resolving the issue. (LOG-5750)
  • Before this update, the Elasticsearch operator overwrote all service account annotations without considering ownership. As a result, the kube-controller-manager recreated service account secrets because it logged the link to the owning service account. With this update, the Elasticsearch operator merges annotations, resolving the issue. (LOG-5776)

1.1.7.2. CVEs

1.1.8. Logging 5.8.8

This release includes OpenShift Logging Bug Fix Release 5.8.8 and OpenShift Logging Bug Fix Release 5.8.8.

1.1.8.1. Bug fixes

  • Before this update, there was a delay in restarting Ingesters when configuring LokiStack, because the Loki Operator sets the write-ahead log replay_memory_ceiling to zero bytes for the 1x.demo size. With this update, the minimum value used for the replay_memory_ceiling has been increased to avoid delays. (LOG-5615)

1.1.8.2. CVEs

1.1.9. Logging 5.8.7

This release includes OpenShift Logging Bug Fix Release 5.8.7 Security Update and OpenShift Logging Bug Fix Release 5.8.7.

1.1.9.1. Bug fixes

  • Before this update, the elasticsearch-im-<type>-* pods failed if no <type> logs (audit, infrastructure, or application) were collected. With this update, the pods no longer fail when <type> logs are not collected. (LOG-4949)
  • Before this update, the validation feature for output config required an SSL/TLS URL, even for services such as Amazon CloudWatch or Google Cloud Logging where a URL is not needed by design. With this update, the validation logic for services without URLs are improved, and the error message is more informative. (LOG-5467)
  • Before this update, an issue in the metrics collection code of the Logging Operator caused it to report stale telemetry metrics. With this update, the Logging Operator does not report stale telemetry metrics. (LOG-5471)
  • Before this update, changes to the Logging Operator caused an error due to an incorrect configuration in the ClusterLogForwarder CR. As a result, upgrades to logging deleted the daemonset collector. With this update, the Logging Operator re-creates collector daemonsets except when a Not authorized to collect error occurs. (LOG-5514)

1.1.9.2. CVEs

1.1.10. Logging 5.8.6

This release includes OpenShift Logging Bug Fix Release 5.8.6 Security Update and OpenShift Logging Bug Fix Release 5.8.6.

1.1.10.1. Enhancements

  • Before this update, the Loki Operator did not validate the Amazon Simple Storage Service (S3) endpoint used in the storage secret. With this update, the validation process ensures the S3 endpoint is a valid S3 URL, and the LokiStack status updates to indicate any invalid URLs. (LOG-5392)
  • Before this update, the Loki Operator configured Loki to use path-based style access for the Amazon Simple Storage Service (S3), which has been deprecated. With this update, the Loki Operator defaults to virtual-host style without users needing to change their configuration. (LOG-5402)

1.1.10.2. Bug fixes

  • Before this update, the Elastisearch Operator ServiceMonitor in the openshift-operators-redhat namespace used static token and certificate authority (CA) files for authentication, causing errors in the Prometheus Operator in the User Workload Monitoring specification on the ServiceMonitor configuration. With this update, the Elastisearch Operator ServiceMonitor in the openshift-operators-redhat namespace now references a service account token secret by a LocalReference object. This approach allows the User Workload Monitoring specifications in the Prometheus Operator to handle the Elastisearch Operator ServiceMonitor successfully. This enables Prometheus to scrape the Elastisearch Operator metrics. (LOG-5164)
  • Before this update, the Loki Operator did not validate the Amazon Simple Storage Service (S3) endpoint URL format used in the storage secret. With this update, the S3 endpoint URL goes through a validation step that reflects on the status of the LokiStack. (LOG-5398)

1.1.10.3. CVEs

1.1.11. Logging 5.8.5

This release includes OpenShift Logging Bug Fix Release 5.8.5.

1.1.11.1. Bug fixes

  • Before this update, the configuration of the Loki Operator’s ServiceMonitor could match many Kubernetes services, resulting in the Loki Operator’s metrics being collected multiple times. With this update, the configuration of ServiceMonitor now only matches the dedicated metrics service. (LOG-5250)
  • Before this update, the Red Hat build pipeline did not use the existing build details in Loki builds and omitted information such as revision, branch, and version. With this update, the Red Hat build pipeline now adds these details to the Loki builds, fixing the issue. (LOG-5201)
  • Before this update, the Loki Operator checked if the pods were running to decide if the LokiStack was ready. With this update, it also checks if the pods are ready, so that the readiness of the LokiStack reflects the state of its components. (LOG-5171)
  • Before this update, running a query for log metrics caused an error in the histogram. With this update, the histogram toggle function and the chart are disabled and hidden because the histogram doesn’t work with log metrics. (LOG-5044)
  • Before this update, the Loki and Elasticsearch bundle had the wrong maxOpenShiftVersion, resulting in IncompatibleOperatorsInstalled alerts. With this update, including 4.16 as the maxOpenShiftVersion property in the bundle fixes the issue. (LOG-5272)
  • Before this update, the build pipeline did not include linker flags for the build date, causing Loki builds to show empty strings for buildDate and goVersion. With this update, adding the missing linker flags in the build pipeline fixes the issue. (LOG-5274)
  • Before this update, a bug in LogQL parsing left out some line filters from the query. With this update, the parsing now includes all the line filters while keeping the original query unchanged. (LOG-5270)
  • Before this update, the Loki Operator ServiceMonitor in the openshift-operators-redhat namespace used static token and CA files for authentication, causing errors in the Prometheus Operator in the User Workload Monitoring spec on the ServiceMonitor configuration. With this update, the Loki Operator ServiceMonitor in openshift-operators-redhat namespace now references a service account token secret by a LocalReference object. This approach allows the User Workload Monitoring spec in the Prometheus Operator to handle the Loki Operator ServiceMonitor successfully, enabling Prometheus to scrape the Loki Operator metrics. (LOG-5240)

1.1.11.2. CVEs

1.1.12. Logging 5.8.4

This release includes OpenShift Logging Bug Fix Release 5.8.4.

1.1.12.1. Bug fixes

  • Before this update, the developer console’s logs did not account for the current namespace, resulting in query rejection for users without cluster-wide log access. With this update, all supported OCP versions ensure correct namespace inclusion. (LOG-4905)
  • Before this update, the Cluster Logging Operator deployed ClusterRoles supporting LokiStack deployments only when the default log output was LokiStack. With this update, the roles are split into two groups: read and write. The write roles deploys based on the setting of the default log storage, just like all the roles used to do before. The read roles deploys based on whether the logging console plugin is active. (LOG-4987)
  • Before this update, multiple ClusterLogForwarders defining the same input receiver name had their service endlessly reconciled because of changing ownerReferences on one service. With this update, each receiver input will have its own service named with the convention of <CLF.Name>-<input.Name>. (LOG-5009)
  • Before this update, the ClusterLogForwarder did not report errors when forwarding logs to cloudwatch without a secret. With this update, the following error message appears when forwarding logs to cloudwatch without a secret: secret must be provided for cloudwatch output. (LOG-5021)
  • Before this update, the log_forwarder_input_info included application, infrastructure, and audit input metric points. With this update, http is also added as a metric point. (LOG-5043)

1.1.12.2. CVEs

1.1.13. Logging 5.8.3

This release includes Logging Bug Fix 5.8.3 and Logging Security Fix 5.8.3

1.1.13.1. Bug fixes

  • Before this update, when configured to read a custom S3 Certificate Authority the Loki Operator would not automatically update the configuration when the name of the ConfigMap or the contents changed. With this update, the Loki Operator is watching for changes to the ConfigMap and automatically updates the generated configuration. (LOG-4969)
  • Before this update, Loki outputs configured without a valid URL caused the collector pods to crash. With this update, outputs are subject to URL validation, resolving the issue. (LOG-4822)
  • Before this update the Cluster Logging Operator would generate collector configuration fields for outputs that did not specify a secret to use the service account bearer token. With this update, an output does not require authentication, resolving the issue. (LOG-4962)
  • Before this update, the tls.insecureSkipVerify field of an output was not set to a value of true without a secret defined. With this update, a secret is no longer required to set this value. (LOG-4963)
  • Before this update, output configurations allowed the combination of an insecure (HTTP) URL with TLS authentication. With this update, outputs configured for TLS authentication require a secure (HTTPS) URL. (LOG-4893)

1.1.13.2. CVEs

1.1.14. Logging 5.8.2

This release includes OpenShift Logging Bug Fix Release 5.8.2.

1.1.14.1. Bug fixes

  • Before this update, the LokiStack ruler pods would not format the IPv6 pod IP in HTTP URLs used for cross pod communication, causing querying rules and alerts through the Prometheus-compatible API to fail. With this update, the LokiStack ruler pods encapsulate the IPv6 pod IP in square brackets, resolving the issue. (LOG-4890)
  • Before this update, the developer console logs did not account for the current namespace, resulting in query rejection for users without cluster-wide log access. With this update, namespace inclusion has been corrected, resolving the issue. (LOG-4947)
  • Before this update, the logging view plugin of the OpenShift Container Platform web console did not allow for custom node placement and tolerations. With this update, defining custom node placements and tolerations has been added to the logging view plugin of the OpenShift Container Platform web console. (LOG-4912)

1.1.14.2. CVEs

1.1.15. Logging 5.8.1

This release includes OpenShift Logging Bug Fix Release 5.8.1 and OpenShift Logging Bug Fix Release 5.8.1 Kibana.

1.1.15.1. Enhancements

1.1.15.1.1. Log Collection
  • With this update, while configuring Vector as a collector, you can add logic to the Red Hat OpenShift Logging Operator to use a token specified in the secret in place of the token associated with the service account. (LOG-4780)
  • With this update, the BoltDB Shipper Loki dashboards are now renamed to Index dashboards. (LOG-4828)

1.1.15.2. Bug fixes

  • Before this update, the ClusterLogForwarder created empty indices after enabling the parsing of JSON logs, even when the rollover conditions were not met. With this update, the ClusterLogForwarder skips the rollover when the write-index is empty. (LOG-4452)
  • Before this update, the Vector set the default log level incorrectly. With this update, the correct log level is set by improving the enhancement of regular expression, or regexp, for log level detection. (LOG-4480)
  • Before this update, during the process of creating index patterns, the default alias was missing from the initial index in each log output. As a result, Kibana users were unable to create index patterns by using OpenShift Elasticsearch Operator. This update adds the missing aliases to OpenShift Elasticsearch Operator, resolving the issue. Kibana users can now create index patterns that include the {app,infra,audit}-000001 indexes. (LOG-4683)
  • Before this update, Fluentd collector pods were in a CrashLoopBackOff state due to binding of the Prometheus server on IPv6 clusters. With this update, the collectors work properly on IPv6 clusters. (LOG-4706)
  • Before this update, the Red Hat OpenShift Logging Operator would undergo numerous reconciliations whenever there was a change in the ClusterLogForwarder. With this update, the Red Hat OpenShift Logging Operator disregards the status changes in the collector daemonsets that triggered the reconciliations. (LOG-4741)
  • Before this update, the Vector log collector pods were stuck in the CrashLoopBackOff state on IBM Power machines. With this update, the Vector log collector pods start successfully on IBM Power architecture machines. (LOG-4768)
  • Before this update, forwarding with a legacy forwarder to an internal LokiStack would produce SSL certificate errors using Fluentd collector pods. With this update, the log collector service account is used by default for authentication, using the associated token and ca.crt. (LOG-4791)
  • Before this update, forwarding with a legacy forwarder to an internal LokiStack would produce SSL certificate errors using Vector collector pods. With this update, the log collector service account is used by default for authentication and also using the associated token and ca.crt. (LOG-4852)
  • Before this fix, IPv6 addresses would not be parsed correctly after evaluating a host or multiple hosts for placeholders. With this update, IPv6 addresses are correctly parsed. (LOG-4811)
  • Before this update, it was necessary to create a ClusterRoleBinding to collect audit permissions for HTTP receiver inputs. With this update, it is not necessary to create the ClusterRoleBinding because the endpoint already depends upon the cluster certificate authority. (LOG-4815)
  • Before this update, the Loki Operator did not mount a custom CA bundle to the ruler pods. As a result, during the process to evaluate alerting or recording rules, object storage access failed. With this update, the Loki Operator mounts the custom CA bundle to all ruler pods. The ruler pods can download logs from object storage to evaluate alerting or recording rules. (LOG-4836)
  • Before this update, while removing the inputs.receiver section in the ClusterLogForwarder, the HTTP input services and its associated secrets were not deleted. With this update, the HTTP input resources are deleted when not needed. (LOG-4612)
  • Before this update, the ClusterLogForwarder indicated validation errors in the status, but the outputs and the pipeline status did not accurately reflect the specific issues. With this update, the pipeline status displays the validation failure reasons correctly in case of misconfigured outputs, inputs, or filters. (LOG-4821)
  • Before this update, changing a LogQL query that used controls such as time range or severity changed the label matcher operator defining it like a regular expression. With this update, regular expression operators remain unchanged when updating the query. (LOG-4841)

1.1.15.3. CVEs

1.1.16. Logging 5.8.0

This release includes OpenShift Logging Bug Fix Release 5.8.0 and OpenShift Logging Bug Fix Release 5.8.0 Kibana.

1.1.16.1. Deprecation notice

In Logging 5.8, Elasticsearch, Fluentd, and Kibana are deprecated and are planned to be removed in Logging 6.0, which is expected to be shipped alongside a future release of OpenShift Container Platform. Red Hat will provide critical and above CVE bug fixes and support for these components during the current release lifecycle, but these components will no longer receive feature enhancements. The Vector-based collector provided by the Red Hat OpenShift Logging Operator and LokiStack provided by the Loki Operator are the preferred Operators for log collection and storage. We encourage all users to adopt the Vector and Loki log stack, as this will be the stack that will be enhanced going forward.

1.1.16.2. Enhancements

1.1.16.2.1. Log Collection
  • With this update, the LogFileMetricExporter is no longer deployed with the collector by default. You must manually create a LogFileMetricExporter custom resource (CR) to generate metrics from the logs produced by running containers. If you do not create the LogFileMetricExporter CR, you may see a No datapoints found message in the OpenShift Container Platform web console dashboard for Produced Logs. (LOG-3819)

  • With this update, you can deploy multiple, isolated, and RBAC-protected ClusterLogForwarder custom resource (CR) instances in any namespace. This allows independent groups to forward desired logs to any destination while isolating their configuration from other collector deployments. (LOG-1343)

    Important

    In order to support multi-cluster log forwarding in additional namespaces other than the openshift-logging namespace, you must update the Red Hat OpenShift Logging Operator to watch all namespaces. This functionality is supported by default in new Red Hat OpenShift Logging Operator version 5.8 installations.

  • With this update, you can use the flow control or rate limiting mechanism to limit the volume of log data that can be collected or forwarded by dropping excess log records. The input limits prevent poorly-performing containers from overloading the Logging and the output limits put a ceiling on the rate of logs shipped to a given data store. (LOG-884)
  • With this update, you can configure the log collector to look for HTTP connections and receive logs as an HTTP server, also known as a webhook. (LOG-4562)
  • With this update, you can configure audit polices to control which Kubernetes and OpenShift API server events are forwarded by the log collector. (LOG-3982)
1.1.16.2.2. Log Storage
  • With this update, LokiStack administrators can have more fine-grained control over who can access which logs by granting access to logs on a namespace basis. (LOG-3841)
  • With this update, the Loki Operator introduces PodDisruptionBudget configuration on LokiStack deployments to ensure normal operations during OpenShift Container Platform cluster restarts by keeping ingestion and the query path available. (LOG-3839)
  • With this update, the reliability of existing LokiStack installations are seamlessly improved by applying a set of default Affinity and Anti-Affinity policies. (LOG-3840)
  • With this update, you can manage zone-aware data replication as an administrator in LokiStack, in order to enhance reliability in the event of a zone failure. (LOG-3266)
  • With this update, a new supported small-scale LokiStack size of 1x.extra-small is introduced for OpenShift Container Platform clusters hosting a few workloads and smaller ingestion volumes (up to 100GB/day). (LOG-4329)
  • With this update, the LokiStack administrator has access to an official Loki dashboard to inspect the storage performance and the health of each component. (LOG-4327)
1.1.16.2.3. Log Console
  • With this update, you can enable the Logging Console Plugin when Elasticsearch is the default Log Store. (LOG-3856)
  • With this update, OpenShift Container Platform application owners can receive notifications for application log-based alerts on the OpenShift Container Platform web console Developer perspective for OpenShift Container Platform version 4.14 and later. (LOG-3548)

1.1.16.3. Known Issues

  • Currently, Splunk log forwarding might not work after upgrading to version 5.8 of the Red Hat OpenShift Logging Operator. This issue is caused by transitioning from OpenSSL version 1.1.1 to version 3.0.7. In the newer OpenSSL version, there is a default behavior change, where connections to TLS 1.2 endpoints are rejected if they do not expose the RFC 5746 extension.

    As a workaround, enable TLS 1.3 support on the TLS terminating load balancer in front of the Splunk HEC (HTTP Event Collector) endpoint. Splunk is a third-party system and this should be configured from the Splunk end.

  • Currently, there is a flaw in handling multiplexed streams in the HTTP/2 protocol, where you can repeatedly make a request for a new multiplex stream and immediately send an RST_STREAM frame to cancel it. This created extra work for the server set up and tore down the streams, resulting in a denial of service due to server resource consumption. There is currently no workaround for this issue. (LOG-4609)
  • Currently, when using FluentD as the collector, the collector pod cannot start on the OpenShift Container Platform IPv6-enabled cluster. The pod logs produce the fluentd pod [error]: unexpected error error_class=SocketError error="getaddrinfo: Name or service not known error. There is currently no workaround for this issue. (LOG-4706)
  • Currently, the log alert is not available on an IPv6-enabled cluster. There is currently no workaround for this issue. (LOG-4709)
  • Currently, must-gather cannot gather any logs on a FIPS-enabled cluster, because the required OpenSSL library is not available in the cluster-logging-rhel9-operator. There is currently no workaround for this issue. (LOG-4403)
  • Currently, when deploying the logging version 5.8 on a FIPS-enabled cluster, the collector pods cannot start and are stuck in CrashLoopBackOff status, while using FluentD as a collector. There is currently no workaround for this issue. (LOG-3933)

1.1.16.4. CVEs

1.2. Logging 5.7

Note

Logging is provided as an installable component, with a distinct release cycle from the core OpenShift Container Platform. The Red Hat OpenShift Container Platform Life Cycle Policy outlines release compatibility.

Note

The stable channel only provides updates to the most recent release of logging. To continue receiving updates for prior releases, you must change your subscription channel to stable-x.y, where x.y represents the major and minor version of logging you have installed. For example, stable-5.7.

1.2.1. Logging 5.7.15

This release includes OpenShift Logging Bug Fix 5.7.15.

1.2.1.1. Bug fixes

  • Before this update, there was a delay in restarting Ingesters when configuring LokiStack, because the Loki Operator sets the write-ahead log replay_memory_ceiling to zero bytes for the 1x.demo size. With this update, the minimum value used for the replay_memory_ceiling has been increased to avoid delays. (LOG-5616)

1.2.1.2. CVEs

1.2.2. Logging 5.7.14

This release includes OpenShift Logging Bug Fix 5.7.14.

1.2.2.1. Bug fixes

  • Before this update, an issue in the metrics collection code of the Logging Operator caused it to report stale telemetry metrics. With this update, the Logging Operator does not report stale telemetry metrics. (LOG-5472)

1.2.2.2. CVEs

1.2.3. Logging 5.7.13

This release includes OpenShift Logging Bug Fix 5.7.13.

1.2.3.1. Enhancements

  • Before this update, the Loki Operator configured Loki to use path-based style access for the Amazon Simple Storage Service (S3), which has been deprecated. With this update, the Loki Operator defaults to virtual-host style without users needing to change their configuration. (LOG-5403)
  • Before this update, the Loki Operator did not validate the Amazon Simple Storage Service (S3) endpoint used in the storage secret. With this update, the validation process ensures the S3 endpoint is a valid S3 URL, and the LokiStack status updates to indicate any invalid URLs. (LOG-5393)

1.2.3.2. Bug fixes

  • Before this update, the Elastisearch Operator ServiceMonitor in the openshift-operators-redhat namespace used static token and certificate authority (CA) files for authentication, causing errors in the Prometheus Operator in the User Workload Monitoring specification on the ServiceMonitor configuration. With this update, the Elastisearch Operator ServiceMonitor in the openshift-operators-redhat namespace now references a service account token secret by a LocalReference object. This approach allows the User Workload Monitoring specifications in the Prometheus Operator to handle the Elastisearch Operator ServiceMonitor successfully. This enables Prometheus to scrape the Elastisearch Operator metrics. (LOG-5243)
  • Before this update, the Loki Operator did not validate the Amazon Simple Storage Service (S3) endpoint URL format used in the storage secret. With this update, the S3 endpoint URL goes through a validation step that reflects on the status of the LokiStack. (LOG-5399)

1.2.3.3. CVEs

1.2.4. Logging 5.7.12

This release includes OpenShift Logging Bug Fix 5.7.12.

1.2.4.1. Bug fixes

  • Before this update, the Loki Operator checked if the pods were running to decide if the LokiStack was ready. With this update, it also checks if the pods are ready, so that the readiness of the LokiStack reflects the state of its components. (LOG-5172)
  • Before this update, the Red Hat build pipeline didn’t use the existing build details in Loki builds and omitted information such as revision, branch, and version. With this update, the Red Hat build pipeline now adds these details to the Loki builds, fixing the issue. (LOG-5202)
  • Before this update, the configuration of the Loki Operator’s ServiceMonitor could match many Kubernetes services, resulting in the Loki Operator’s metrics being collected multiple times. With this update, the configuration of ServiceMonitor now only matches the dedicated metrics service. (LOG-5251)
  • Before this update, the build pipeline did not include linker flags for the build date, causing Loki builds to show empty strings for buildDate and goVersion. With this update, adding the missing linker flags in the build pipeline fixes the issue. (LOG-5275)
  • Before this update, the Loki Operator ServiceMonitor in the openshift-operators-redhat namespace used static token and CA files for authentication, causing errors in the Prometheus Operator in the User Workload Monitoring spec on the ServiceMonitor configuration. With this update, the Loki Operator ServiceMonitor in openshift-operators-redhat namespace now references a service account token secret by a LocalReference object. This approach allows the User Workload Monitoring spec in the Prometheus Operator to handle the Loki Operator ServiceMonitor successfully, enabling Prometheus to scrape the Loki Operator metrics.

  • Before this fix, IPv6 addresses would not be parsed correctly after evaluating a host or multiple hosts for placeholders. With this update, IPv6 addresses are correctly parsed. (LOG-4281)
  • Before this update, the Vector failed to start on IPv4-only nodes. As a result, it failed to create a listener for its metrics endpoint with the following error: Failed to start Prometheus exporter: TCP bind failed: Address family not supported by protocol (os error 97). With this update, the Vector operates normally on IPv4-only nodes. (LOG-4589)
  • Before this update, during the process of creating index patterns, the default alias was missing from the initial index in each log output. As a result, Kibana users were unable to create index patterns by using OpenShift Elasticsearch Operator. This update adds the missing aliases to OpenShift Elasticsearch Operator, resolving the issue. Kibana users can now create index patterns that include the {app,infra,audit}-000001 indexes. (LOG-4806)
  • Before this update, the Loki Operator did not mount a custom CA bundle to the ruler pods. As a result, during the process to evaluate alerting or recording rules, object storage access failed. With this update, the Loki Operator mounts the custom CA bundle to all ruler pods. The ruler pods can download logs from object storage to evaluate alerting or recording rules. (LOG-4837)
  • Before this update, changing a LogQL query using controls such as time range or severity changed the label matcher operator as though it was defined like a regular expression. With this update, regular expression operators remain unchanged when updating the query. (LOG-4842)
  • Before this update, the Vector collector deployments relied upon the default retry and buffering behavior. As a result, the delivery pipeline backed up trying to deliver every message when the availability of an output was unstable. With this update, the Vector collector deployments limit the number of message retries and drop messages after the threshold has been exceeded. (LOG-4536)

1.2.8.1. Bug fixes

  • Before this update, there was a potential conflict when the same name was used for the outputRefs and inputRefs parameters in the ClusterLogForwarder custom resource (CR). As a result, the collector pods entered in a CrashLoopBackOff status. With this update, the output labels contain the OUTPUT_ prefix to ensure a distinction between output labels and pipeline names. (LOG-4383)
  • Before this update, while configuring the JSON log parser, if you did not set the structuredTypeKey or structuredTypeName parameters for the Cluster Logging Operator, no alert would display about an invalid configuration. With this update, the Cluster Logging Operator informs you about the configuration issue. (LOG-4441)
  • Before this update, if the hecToken key was missing or incorrect in the secret specified for a Splunk output, the validation failed because the Vector forwarded logs to Splunk without a token. With this update, if the hecToken key is missing or incorrect, the validation fails with the A non-empty hecToken entry is required error message. (LOG-4580)
  • Before this update, selecting a date from the Custom time range for logs caused an error in the web console. With this update, you can select a date from the time range model in the web console successfully. (LOG-4684)

  • Before this update, FluentD normalized the logs emitted by the EventRouter differently from Vector. With this update, the Vector produces log records in a consistent format. (LOG-4178)
  • Before this update, there was an error in the query used for the FluentD Buffer Availability graph in the metrics dashboard created by the Cluster Logging Operator as it showed the minimum buffer usage. With this update, the graph shows the maximum buffer usage and is now renamed to FluentD Buffer Usage. (LOG-4555)
  • Before this update, deploying a LokiStack on IPv6-only or dual-stack OpenShift Container Platform clusters caused the LokiStack memberlist registration to fail. As a result, the distributor pods went into a crash loop. With this update, an administrator can enable IPv6 by setting the lokistack.spec.hashRing.memberlist.enableIPv6: value to true, which resolves the issue. (LOG-4569)
  • Before this update, the log collector relied on the default configuration settings for reading the container log lines. As a result, the log collector did not read the rotated files efficiently. With this update, there is an increase in the number of bytes read, which allows the log collector to efficiently process rotated files. (LOG-4575)
  • Before this update, the unused metrics in the Event Router caused the container to fail due to excessive memory usage. With this update, there is reduction in the memory usage of the Event Router by removing the unused metrics. (LOG-4686)

1.2.10.1. Bug fixes

  • Before this update, the collector relied on the default configuration settings for reading the container log lines. As a result, the collector did not read the rotated files efficiently. With this update, there is an increase in the number of bytes read, which allows the collector to efficiently process rotated files. (LOG-4501)
  • Before this update, when users pasted a URL with predefined filters, some filters did not reflect. With this update, the UI reflects all the filters in the URL. (LOG-4459)
  • Before this update, forwarding to Loki using custom labels generated an error when switching from Fluentd to Vector. With this update, the Vector configuration sanitizes labels in the same way as Fluentd to ensure the collector starts and correctly processes labels. (LOG-4460)
  • Before this update, the Observability Logs console search field did not accept special characters that it should escape. With this update, it is escaping special characters properly in the query. (LOG-4456)
  • Before this update, the following warning message appeared while sending logs to Splunk: Timestamp was not found. With this update, the change overrides the name of the log field used to retrieve the Timestamp and sends it to Splunk without warning. (LOG-4413)
  • Before this update, the CPU and memory usage of Vector was increasing over time. With this update, the Vector configuration now contains the expire_metrics_secs=60 setting to limit the lifetime of the metrics and cap the associated CPU usage and memory footprint. (LOG-4171)
  • Before this update, the LokiStack gateway cached authorized requests very broadly. As a result, this caused wrong authorization results. With this update, LokiStack gateway caches on a more fine-grained basis which resolves this issue. (LOG-4393)
  • Before this update, the Fluentd runtime image included builder tools which were unnecessary at runtime. With this update, the builder tools are removed, resolving the issue. (LOG-4467)

1.2.11.1. Bug fixes

  • Before this update, when forwarding logs to CloudWatch, a namespaceUUID value was not appended to the logGroupName field. With this update, the namespaceUUID value is included, so a logGroupName in CloudWatch appears as logGroupName: vectorcw.b443fb9e-bd4c-4b6a-b9d3-c0097f9ed286. (LOG-2701)
  • Before this update, when forwarding logs over HTTP to an off-cluster destination, the Vector collector was unable to authenticate to the cluster-wide HTTP proxy even though correct credentials were provided in the proxy URL. With this update, the Vector log collector can now authenticate to the cluster-wide HTTP proxy. (LOG-3381)
  • Before this update, the Operator would fail if the Fluentd collector was configured with Splunk as an output, due to this configuration being unsupported. With this update, configuration validation rejects unsupported outputs, resolving the issue. (LOG-4237)
  • Before this update, when the Vector collector was updated an enabled = true value in the TLS configuration for AWS Cloudwatch logs and the GCP Stackdriver caused a configuration error. With this update, enabled = true value will be removed for these outputs, resolving the issue. (LOG-4242)
  • Before this update, the Vector collector occasionally panicked with the following error message in its log: thread 'vector-worker' panicked at 'all branches are disabled and there is no else branch', src/kubernetes/reflector.rs:26:9. With this update, the error has been resolved. (LOG-4275)
  • Before this update, an issue in the Loki Operator caused the alert-manager configuration for the application tenant to disappear if the Operator was configured with additional options for that tenant. With this update, the generated Loki configuration now contains both the custom and the auto-generated configuration. (LOG-4361)
  • Before this update, when multiple roles were used to authenticate using STS with AWS Cloudwatch forwarding, a recent update caused the credentials to be non-unique. With this update, multiple combinations of STS roles and static credentials can once again be used to authenticate with AWS Cloudwatch. (LOG-4368)
  • Before this update, Loki filtered label values for active streams but did not remove duplicates, making Grafana’s Label Browser unusable. With this update, Loki filters out duplicate label values for active streams, resolving the issue. (LOG-4389)
  • Pipelines with no name field specified in the ClusterLogForwarder custom resource (CR) stopped working after upgrading to OpenShift Logging 5.7. With this update, the error has been resolved. (LOG-4120)

1.2.12.1. Bug fixes

  • Before this update, when viewing logs within the OpenShift Container Platform web console, cached files caused the data to not refresh. With this update the bootstrap files are not cached, resolving the issue. (LOG-4100)
  • Before this update, the Loki Operator reset errors in a way that made identifying configuration problems difficult to troubleshoot. With this update, errors persist until the configuration error is resolved. (LOG-4156)
  • Before this update, the LokiStack ruler did not restart after changes were made to the RulerConfig custom resource (CR). With this update, the Loki Operator restarts the ruler pods after the RulerConfig CR is updated. (LOG-4161)
  • Before this update, the vector collector terminated unexpectedly when input match label values contained a / character within the ClusterLogForwarder. This update resolves the issue by quoting the match label, enabling the collector to start and collect logs. (LOG-4176)
  • Before this update, the Loki Operator terminated unexpectedly when a LokiStack CR defined tenant limits, but not global limits. With this update, the Loki Operator can process LokiStack CRs without global limits, resolving the issue. (LOG-4198)
  • Before this update, Fluentd did not send logs to an Elasticsearch cluster when the private key provided was passphrase-protected. With this update, Fluentd properly handles passphrase-protected private keys when establishing a connection with Elasticsearch. (LOG-4258)
  • Before this update, clusters with more than 8,000 namespaces caused Elasticsearch to reject queries because the list of namespaces was larger than the http.max_header_size setting. With this update, the default value for header size has been increased, resolving the issue. (LOG-4277)
  • Before this update, label values containing a / character within the ClusterLogForwarder CR would cause the collector to terminate unexpectedly. With this update, slashes are replaced with underscores, resolving the issue. (LOG-4095)
  • Before this update, the Cluster Logging Operator terminated unexpectedly when set to an unmanaged state. With this update, a check to ensure that the ClusterLogging resource is in the correct Management state before initiating the reconciliation of the ClusterLogForwarder CR, resolving the issue. (LOG-4177)
  • Before this update, when viewing logs within the OpenShift Container Platform web console, selecting a time range by dragging over the histogram didn’t work on the aggregated logs view inside the pod detail. With this update, the time range can be selected by dragging on the histogram in this view. (LOG-4108)
  • Before this update, when viewing logs within the OpenShift Container Platform web console, queries longer than 30 seconds timed out. With this update, the timeout value can be configured in the configmap/logging-view-plugin. (LOG-3498)
  • Before this update, when viewing logs within the OpenShift Container Platform web console, clicking the more data available option loaded more log entries only the first time it was clicked. With this update, more entries are loaded with each click. (OU-188)
  • Before this update, when viewing logs within the OpenShift Container Platform web console, clicking the streaming option would only display the streaming logs message without showing the actual logs. With this update, both the message and the log stream are displayed correctly. (OU-166)

1.2.13. Logging 5.7.2

This release includes OpenShift Logging Bug Fix Release 5.7.2.

1.2.13.1. Bug fixes

  • Before this update, it was not possible to delete the openshift-logging namespace directly due to the presence of a pending finalizer. With this update, the finalizer is no longer utilized, enabling direct deletion of the namespace. (LOG-3316)
  • Before this update, the run.sh script would display an incorrect chunk_limit_size value if it was changed according to the OpenShift Container Platform documentation. However, when setting the chunk_limit_size via the environment variable $BUFFER_SIZE_LIMIT, the script would show the correct value. With this update, the run.sh script now consistently displays the correct chunk_limit_size value in both scenarios. (LOG-3330)
  • Before this update, the OpenShift Container Platform web console’s logging view plugin did not allow for custom node placement or tolerations. This update adds the ability to define node placement and tolerations for the logging view plugin. (LOG-3749)
  • Before this update, the Cluster Logging Operator encountered an Unsupported Media Type exception when trying to send logs to DataDog via the Fluentd HTTP Plugin. With this update, users can seamlessly assign the content type for log forwarding by configuring the HTTP header Content-Type. The value provided is automatically assigned to the content_type parameter within the plugin, ensuring successful log transmission. (LOG-3784)
  • Before this update, when the detectMultilineErrors field was set to true in the ClusterLogForwarder custom resource (CR), PHP multi-line errors were recorded as separate log entries, causing the stack trace to be split across multiple messages. With this update, multi-line error detection for PHP is enabled, ensuring that the entire stack trace is included in a single log message. (LOG-3878)
  • Before this update, ClusterLogForwarder pipelines containing a space in their name caused the Vector collector pods to continuously crash. With this update, all spaces, dashes (-), and dots (.) in pipeline names are replaced with underscores (_). (LOG-3945)
  • Before this update, the log_forwarder_output metric did not include the http parameter. This update adds the missing parameter to the metric. (LOG-3997)
  • Before this update, Fluentd did not identify some multi-line JavaScript client exceptions when they ended with a colon. With this update, the Fluentd buffer name is prefixed with an underscore, resolving the issue. (LOG-4019)
  • Before this update, when configuring log forwarding to write to a Kafka output topic which matched a key in the payload, logs dropped due to an error. With this update, Fluentd’s buffer name has been prefixed with an underscore, resolving the issue.(LOG-4027)
  • Before this update, the LokiStack gateway returned label values for namespaces without applying the access rights of a user. With this update, the LokiStack gateway applies permissions to label value requests, resolving the issue. (LOG-4049)

  • Before this update, the Cluster Logging Operator API required a certificate to be provided by a secret when the tls.insecureSkipVerify option was set to true. With this update, the Cluster Logging Operator API no longer requires a certificate to be provided by a secret in such cases. The following configuration has been added to the Operator’s CR: 

    tls.verify_certificate = false
tls.verify_hostname = false

    (LOG-3445)

  • Before this update, the LokiStack route configuration caused queries running longer than 30 seconds to timeout. With this update, the LokiStack global and per-tenant queryTimeout settings affect the route timeout settings, resolving the issue. (LOG-4052)
  • Before this update, a prior fix to remove defaulting of the collection.type resulted in the Operator no longer honoring the deprecated specs for resource, node selections, and tolerations. This update modifies the Operator behavior to always prefer the collection.logs spec over those of collection. This varies from previous behavior that allowed using both the preferred fields and deprecated fields but would ignore the deprecated fields when collection.type was populated. (LOG-4185)
  • Before this update, the Vector log collector did not generate TLS configuration for forwarding logs to multiple Kafka brokers if the broker URLs were not specified in the output. With this update, TLS configuration is generated appropriately for multiple brokers. (LOG-4163)
  • Before this update, the option to enable passphrase for log forwarding to Kafka was unavailable. This limitation presented a security risk as it could potentially expose sensitive information. With this update, users now have a seamless option to enable passphrase for log forwarding to Kafka. (LOG-3314)
  • Before this update, Vector log collector did not honor the tlsSecurityProfile settings for outgoing TLS connections. After this update, Vector handles TLS connection settings appropriately. (LOG-4011)
  • Before this update, not all available output types were included in the log_forwarder_output_info metrics. With this update, metrics contain Splunk and Google Cloud Logging data which was missing previously. (LOG-4098)
  • Before this update, when follow_inodes was set to true, the Fluentd collector could crash on file rotation. With this update, the follow_inodes setting does not crash the collector. (LOG-4151)
  • Before this update, the Fluentd collector could incorrectly close files that should be watched because of how those files were tracked. With this update, the tracking parameters have been corrected. (LOG-4149)

  • Before this update, forwarding logs with the Vector collector and naming a pipeline in the ClusterLogForwarder instance audit, application or infrastructure resulted in collector pods staying in the CrashLoopBackOff state with the following error in the collector log: 

    ERROR vector::cli: Configuration error. error=redefinition of table transforms.audit for key transforms.audit

    After this update, pipeline names no longer clash with reserved input names, and pipelines can be named audit, application or infrastructure. (LOG-4218)

  • Before this update, when forwarding logs to a syslog destination with the Vector collector and setting the addLogSource flag to true, the following extra empty fields were added to the forwarded messages: namespace_name=, container_name=, and pod_name=. With this update, these fields are no longer added to journal logs. (LOG-4219)
  • Before this update, when a structuredTypeKey was not found, and a structuredTypeName was not specified, log messages were still parsed into structured object. With this update, parsing of logs is as expected. (LOG-4220)

1.2.14.1. Bug fixes

  • Before this update, the presence of numerous noisy messages within the Cluster Logging Operator pod logs caused reduced log readability, and increased difficulty in identifying important system events. With this update, the issue is resolved by significantly reducing the noisy messages within Cluster Logging Operator pod logs. (LOG-3482)
  • Before this update, the API server would reset the value for the CollectorSpec.Type field to vector, even when the custom resource used a different value. This update removes the default for the CollectorSpec.Type field to restore the previous behavior. (LOG-4086)
  • Before this update, a time range could not be selected in the OpenShift Container Platform web console by clicking and dragging over the logs histogram. With this update, clicking and dragging can be used to successfully select a time range. (LOG-4501)
  • Before this update, clicking on the Show Resources link in the OpenShift Container Platform web console did not produce any effect. With this update, the issue is resolved by fixing the functionality of the "Show Resources" link to toggle the display of resources for each log entry. (LOG-3218)

1.3.9.1. Enhancements

  • Before this update, Loki Operator set up Loki to use path-based style access for the Amazon Simple Storage Service (S3), which has been deprecated. With this update, the Loki Operator defaults to virtual-host style without users needing to change their configuration. (LOG-5404)
  • Before this update, the Loki Operator did not validate the Amazon Simple Storage Service (S3) endpoint used in the storage secret. With this update, the validation process ensures the S3 endpoint is a valid S3 URL, and the LokiStack status updates to indicate any invalid URLs. (LOG-5396)

1.3.9.2. Bug fixes

  • Before this update, the Elastisearch Operator ServiceMonitor in the openshift-operators-redhat namespace used static token and certificate authority (CA) files for authentication, causing errors in the Prometheus Operator in the User Workload Monitoring specification on the ServiceMonitor configuration. With this update, the Elastisearch Operator ServiceMonitor in the openshift-operators-redhat namespace now references a service account token secret by a LocalReference object. This approach allows the User Workload Monitoring specifications in the Prometheus Operator to handle the Elastisearch Operator ServiceMonitor successfully. This enables Prometheus to scrape the Elastisearch Operator metrics. (LOG-5244)
  • Before this update, the Loki Operator did not validate the Amazon Simple Storage Service (S3) endpoint URL format used in the storage secret. With this update, the S3 endpoint URL goes through a validation step that reflects on the status of the LokiStack. (LOG-5400)

  • Before this update, the configuration of the ServiceMonitor by Loki Operator could match many Kubernetes services, which led to Loki Operator’s metrics being collected multiple times. With this update, the ServiceMonitor setup now only matches the dedicated metrics service. (LOG-5252)
  • Before this update, the build pipeline did not include linker flags for the build date, causing Loki builds to show empty strings for buildDate and goVersion. With this update, adding the missing linker flags in the build pipeline fixes the issue. (LOG-5276)
  • Before this update, the Loki Operator ServiceMonitor in the openshift-operators-redhat namespace used static token and CA files for authentication, causing errors in the Prometheus Operator in the User Workload Monitoring spec on the ServiceMonitor configuration. With this update, the Loki Operator ServiceMonitor in openshift-operators-redhat namespace now references a service account token secret by a LocalReference object.

As a result, Kibana users were unable to create index patterns by using OpenShift Elasticsearch Operator. This update adds the missing aliases to OpenShift Elasticsearch Operator, resolving the issue. Kibana users can now create index patterns that include the {app,infra,audit}-000001 indexes. (LOG-4807)
  • Before this update, the Loki Operator did not mount a custom CA bundle to the ruler pods. As a result, during the process to evaluate alerting or recording rules, object storage access failed. With this update, the Loki Operator mounts the custom CA bundle to all ruler pods. The ruler pods can download logs from object storage to evaluate alerting or recording rules. (LOG-4838)

This release includes OpenShift Logging Bug Fix Release 5.6.12.

1.3.15.1. Bug fixes

  • Before this update, deploying a LokiStack on IPv6-only or dual-stack OpenShift Container Platform clusters caused the LokiStack memberlist registration to fail. As a result, the distributor pods went into a crash loop. With this update, an administrator can enable IPv6 by setting the lokistack.spec.hashRing.memberlist.enableIPv6: value to true, which resolves the issue. Currently, the log alert is not available on an IPv6-enabled cluster. (LOG-4570)
  • Before this update, there was an error in the query used for the FluentD Buffer Availability graph in the metrics dashboard created by the Cluster Logging Operator as it showed the minimum buffer usage. With this update, the graph shows the maximum buffer usage and is now renamed to FluentD Buffer Usage. (LOG-4579)
  • Before this update, the unused metrics in the Event Router caused the container to fail due to excessive memory usage. With this update, there is reduction in the memory usage of the Event Router by removing the unused metrics. (LOG-4687)

This release includes OpenShift Logging Bug Fix Release 5.6.9.

1.3.17.1. Bug fixes

  • Before this update, when multiple roles were used to authenticate using STS with AWS Cloudwatch forwarding, a recent update caused the credentials to be non-unique. With this update, multiple combinations of STS roles and static credentials can once again be used to authenticate with AWS Cloudwatch. (LOG-4084)
  • Before this update, the Vector collector occasionally panicked with the following error message in its log: thread 'vector-worker' panicked at 'all branches are disabled and there is no else branch', src/kubernetes/reflector.rs:26:9. With this update, the error has been resolved. (LOG-4276)
  • Before this update, Loki filtered label values for active streams but did not remove duplicates, making Grafana’s Label Browser unusable. With this update, Loki filters out duplicate label values for active streams, resolving the issue. (LOG-4390)

1.3.17.2. CVEs

1.3.18. Logging 5.6.8

This release includes OpenShift Logging Bug Fix Release 5.6.8.

1.3.18.1. Bug fixes

  • Before this update, the vector collector terminated unexpectedly when input match label values contained a / character within the ClusterLogForwarder. This update resolves the issue by quoting the match label, enabling the collector to start and collect logs. (LOG-4091)
  • Before this update, when viewing logs within the OpenShift Container Platform web console, clicking the more data available option loaded more log entries only the first time it was clicked. With this update, more entries are loaded with each click. (OU-187)
  • Before this update, when viewing logs within the OpenShift Container Platform web console, clicking the streaming option would only display the streaming logs message without showing the actual logs. With this update, both the message and the log stream are displayed correctly. (OU-189)
  • Before this update, the Loki Operator reset errors in a way that made identifying configuration problems difficult to troubleshoot. With this update, errors persist until the configuration error is resolved. (LOG-4158)
  • Before this update, clusters with more than 8,000 namespaces caused Elasticsearch to reject queries because the list of namespaces was larger than the http.max_header_size setting. With this update, the default value for header size has been increased, resolving the issue. (LOG-4278)

1.3.19. Logging 5.6.5

This release includes OpenShift Logging Bug Fix Release 5.6.5.

1.3.19.1. Bug fixes

  • Before this update, the template definitions prevented Elasticsearch from indexing some labels and namespace_labels, causing issues with data ingestion. With this update, the fix replaces dots and slashes in labels to ensure proper ingestion, effectively resolving the issue. (LOG-3419)
  • Before this update, if the Logs page of the OpenShift Web Console failed to connect to the LokiStack, a generic error message was displayed, providing no additional context or troubleshooting suggestions. With this update, the error message has been enhanced to include more specific details and recommendations for troubleshooting. (LOG-3750)
  • Before this update, time range formats were not validated, leading to errors selecting a custom date range. With this update, time formats are now validated, enabling users to select a valid range. If an invalid time range format is selected, an error message is displayed to the user. (LOG-3583)
  • Before this update, when searching logs in Loki, even if the length of an expression did not exceed 5120 characters, the query would fail in many cases. With this update, query authorization label matchers have been optimized, resolving the issue. (LOG-3480)
  • Before this update, the Loki Operator failed to produce a memberlist configuration that was sufficient for locating all the components when using a memberlist for private IPs. With this update, the fix ensures that the generated configuration includes the advertised port, allowing for successful lookup of all components. (LOG-4008)

1.3.19.2. CVEs

1.3.20. Logging 5.6.4

This release includes OpenShift Logging Bug Fix Release 5.6.4.

1.3.20.1. Bug fixes

  • Before this update, when LokiStack was deployed as the log store, the logs generated by Loki pods were collected and sent to LokiStack. With this update, the logs generated by Loki are excluded from collection and will not be stored. (LOG-3280)
  • Before this update, when the query editor on the Logs page of the OpenShift Web Console was empty, the drop-down menus did not populate. With this update, if an empty query is attempted, an error message is displayed and the drop-down menus now populate as expected. (LOG-3454)
  • Before this update, when the tls.insecureSkipVerify option was set to true, the Cluster Logging Operator would generate incorrect configuration. As a result, the operator would fail to send data to Elasticsearch when attempting to skip certificate validation. With this update, the Cluster Logging Operator generates the correct TLS configuration even when tls.insecureSkipVerify is enabled. As a result, data can be sent successfully to Elasticsearch even when attempting to skip certificate validation. (LOG-3475)
  • Before this update, when structured parsing was enabled and messages were forwarded to multiple destinations, they were not deep copied. This resulted in some of the received logs including the structured message, while others did not. With this update, the configuration generation has been modified to deep copy messages before JSON parsing. As a result, all received messages now have structured messages included, even when they are forwarded to multiple destinations. (LOG-3640)
  • Before this update, if the collection field contained {} it could result in the Operator crashing. With this update, the Operator will ignore this value, allowing the operator to continue running smoothly without interruption. (LOG-3733)
  • Before this update, the nodeSelector attribute for the Gateway component of LokiStack did not have any effect. With this update, the nodeSelector attribute functions as expected. (LOG-3783)
  • Before this update, the static LokiStack memberlist configuration relied solely on private IP networks. As a result, when the OpenShift Container Platform cluster pod network was configured with a public IP range, the LokiStack pods would crashloop. With this update, the LokiStack administrator now has the option to use the pod network for the memberlist configuration. This resolves the issue and prevents the LokiStack pods from entering a crashloop state when the OpenShift Container Platform cluster pod network is configured with a public IP range. (LOG-3814)
  • Before this update, if the tls.insecureSkipVerify field was set to true, the Cluster Logging Operator would generate an incorrect configuration. As a result, the Operator would fail to send data to Elasticsearch when attempting to skip certificate validation. With this update, the Operator generates the correct TLS configuration even when tls.insecureSkipVerify is enabled. As a result, data can be sent successfully to Elasticsearch even when attempting to skip certificate validation. (LOG-3838)
  • Before this update, if the Cluster Logging Operator (CLO) was installed without the Elasticsearch Operator, the CLO pod would continuously display an error message related to the deletion of Elasticsearch. With this update, the CLO now performs additional checks before displaying any error messages. As a result, error messages related to Elasticsearch deletion are no longer displayed in the absence of the Elasticsearch Operator.(LOG-3763)

1.3.21. Logging 5.6.3

This release includes OpenShift Logging Bug Fix Release 5.6.3.

1.3.21.1. Bug fixes

  • Before this update, the operator stored gateway tenant secret information in a config map. With this update, the operator stores this information in a secret. (LOG-3717)
  • Before this update, the Fluentd collector did not capture OAuth login events stored in /var/log/auth-server/audit.log. With this update, Fluentd captures these OAuth login events, resolving the issue. (LOG-3729)

1.3.22. Logging 5.6.2

This release includes OpenShift Logging Bug Fix Release 5.6.2.

1.3.22.1. Bug fixes

  • Before this update, the collector did not set level fields correctly based on priority for systemd logs. With this update, level fields are set correctly. (LOG-3429)
  • Before this update, the Operator incorrectly generated incompatibility warnings on OpenShift Container Platform 4.12 or later. With this update, the Operator max OpenShift Container Platform version value has been corrected, resolving the issue. (LOG-3584)
  • Before this update, creating a ClusterLogForwarder custom resource (CR) with an output value of default did not generate any errors. With this update, an error warning that this value is invalid generates appropriately. (LOG-3437)
  • Before this update, when the ClusterLogForwarder custom resource (CR) had multiple pipelines configured with one output set as default, the collector pods restarted. With this update, the logic for output validation has been corrected, resolving the issue. (LOG-3559)
  • Before this update, collector pods restarted after being created. With this update, the deployed collector does not restart on its own. (LOG-3608)
  • Before this update, patch releases removed previous versions of the Operators from the catalog. This made installing the old versions impossible. This update changes bundle configurations so that previous releases of the same minor version stay in the catalog. (LOG-3635)

1.3.23. Logging 5.6.1

This release includes OpenShift Logging Bug Fix Release 5.6.1.

1.3.23.1. Bug fixes

  • Before this update, the compactor would report TLS certificate errors from communications with the querier when retention was active. With this update, the compactor and querier no longer communicate erroneously over HTTP. (LOG-3494)
  • Before this update, the Loki Operator would not retry setting the status of the LokiStack CR, which caused stale status information. With this update, the Operator retries status information updates on conflict. (LOG-3496)
  • Before this update, the Loki Operator Webhook server caused TLS errors when the kube-apiserver-operator Operator checked the webhook validity. With this update, the Loki Operator Webhook PKI is managed by the Operator Lifecycle Manager (OLM), resolving the issue. (LOG-3510)
  • Before this update, the LokiStack Gateway Labels Enforcer generated parsing errors for valid LogQL queries when using combined label filters with boolean expressions. With this update, the LokiStack LogQL implementation supports label filters with boolean expression and resolves the issue. (LOG-3441), (LOG-3397)
  • Before this update, records written to Elasticsearch would fail if multiple label keys had the same prefix and some keys included dots. With this update, underscores replace dots in label keys, resolving the issue. (LOG-3463)
  • Before this update, the Red Hat OpenShift Logging Operator was not available for OpenShift Container Platform 4.10 clusters because of an incompatibility between OpenShift Container Platform console and the logging-view-plugin. With this update, the plugin is properly integrated with the OpenShift Container Platform 4.10 admin console. (LOG-3447)
  • Before this update the reconciliation of the ClusterLogForwarder custom resource would incorrectly report a degraded status of pipelines that reference the default logstore. With this update, the pipeline validates properly.(LOG-3477)

1.3.23.2. CVEs

1.3.24. Logging 5.6.0

This release includes OpenShift Logging Release 5.6.

1.3.24.1. Deprecation notice

In logging version 5.6, Fluentd is deprecated and is planned to be removed in a future release. Red Hat will provide bug fixes and support for this feature during the current release lifecycle, but this feature will no longer receive enhancements and will be removed. As an alternative to Fluentd, you can use Vector instead.

1.3.24.2. Enhancements

  • With this update, Logging is compliant with OpenShift Container Platform cluster-wide cryptographic policies. (LOG-895)
  • With this update, you can declare per-tenant, per-stream, and global policies retention policies through the LokiStack custom resource, ordered by priority. (LOG-2695)
  • With this update, Splunk is an available output option for log forwarding. (LOG-2913)
  • With this update, Vector replaces Fluentd as the default Collector. (LOG-2222)
  • With this update, the Developer role can access the per-project workload logs they are assigned to within the Log Console Plugin on clusters running OpenShift Container Platform 4.11 and higher. (LOG-3388)

  • With this update, logs from any source contain a field openshift.cluster_id, the unique identifier of the cluster in which the Operator is deployed. You can view the clusterID value by using the following command: 

    $ oc get clusterversion/version -o jsonpath='{.spec.clusterID}{"\n"}'

    (LOG-2715)

1.3.24.3. Known Issues

  • Before this update, Elasticsearch would reject logs if multiple label keys had the same prefix and some keys included the . character. This fixes the limitation of Elasticsearch by replacing . in the label keys with _. As a workaround for this issue, remove the labels that cause errors, or add a namespace to the label. (LOG-3463)

1.3.24.4. Bug fixes

  • Before this update, if you deleted the Kibana Custom Resource, the OpenShift Container Platform web console continued displaying a link to Kibana. With this update, removing the Kibana Custom Resource also removes that link. (LOG-2993)
  • Before this update, a user was not able to view the application logs of namespaces they have access to. With this update, the Loki Operator automatically creates a cluster role and cluster role binding allowing users to read application logs. (LOG-3072)
  • Before this update, the Operator removed any custom outputs defined in the ClusterLogForwarder custom resource when using LokiStack as the default log storage. With this update, the Operator merges custom outputs with the default outputs when processing the ClusterLogForwarder custom resource. (LOG-3090)
  • Before this update, the CA key was used as the volume name for mounting the CA into Loki, causing error states when the CA Key included non-conforming characters, such as dots. With this update, the volume name is standardized to an internal string which resolves the issue. (LOG-3331)
  • Before this update, a default value set within the LokiStack Custom Resource Definition, caused an inability to create a LokiStack instance without a ReplicationFactor of 1. With this update, the operator sets the actual value for the size used. (LOG-3296)
  • Before this update, Vector parsed the message field when JSON parsing was enabled without also defining structuredTypeKey or structuredTypeName values. With this update, a value is required for either structuredTypeKey or structuredTypeName when writing structured logs to Elasticsearch. (LOG-3195)
  • Before this update, the secret creation component of the Elasticsearch Operator modified internal secrets constantly. With this update, the existing secret is properly handled. (LOG-3161)
  • Before this update, the Operator could enter a loop of removing and recreating the collector daemonset while the Elasticsearch or Kibana deployments changed their status. With this update, a fix in the status handling of the Operator resolves the issue. (LOG-3157)
  • Before this update, Kibana had a fixed 24h OAuth cookie expiration time, which resulted in 401 errors in Kibana whenever the accessTokenInactivityTimeout field was set to a value lower than 24h. With this update, Kibana’s OAuth cookie expiration time synchronizes to the accessTokenInactivityTimeout, with a default value of 24h. (LOG-3129)
  • Before this update, the Operators general pattern for reconciling resources was to try and create before attempting to get or update which would lead to constant HTTP 409 responses after creation. With this update, Operators first attempt to retrieve an object and only create or update it if it is either missing or not as specified. (LOG-2919)
  • Before this update, the .level and`.structure.level` fields in Fluentd could contain different values. With this update, the values are the same for each field. (LOG-2819)
  • Before this update, the Operator did not wait for the population of the trusted CA bundle and deployed the collector a second time once the bundle updated. With this update, the Operator waits briefly to see if the bundle has been populated before it continues the collector deployment. (LOG-2789)
  • Before this update, logging telemetry info appeared twice when reviewing metrics. With this update, logging telemetry info displays as expected. (LOG-2315)
  • Before this update, Fluentd pod logs contained a warning message after enabling the JSON parsing addition. With this update, that warning message does not appear. (LOG-1806)
  • Before this update, the must-gather script did not complete because oc needs a folder with write permission to build its cache. With this update, oc has write permissions to a folder, and the must-gather script completes successfully. (LOG-3446)
  • Before this update the log collector SCC could be superseded by other SCCs on the cluster, rendering the collector unusable. This update sets the priority of the log collector SCC so that it takes precedence over the others. (LOG-3235)
  • Before this update, Vector was missing the field sequence, which was added to fluentd as a way to deal with a lack of actual nanoseconds precision. With this update, the field openshift.sequence has been added to the event logs. (LOG-3106)

1.4.9. Logging 5.5.9

This release includes OpenShift Logging Bug Fix Release 5.5.9.

1.4.9.1. Bug fixes

  • Before this update, a problem with the Fluentd collector caused it to not capture OAuth login events stored in /var/log/auth-server/audit.log. This led to incomplete collection of login events from the OAuth service. With this update, the Fluentd collector now resolves this issue by capturing all login events from the OAuth service, including those stored in /var/log/auth-server/audit.log, as expected.(LOG-3730)
  • Before this update, when structured parsing was enabled and messages were forwarded to multiple destinations, they were not deep copied. This resulted in some of the received logs including the structured message, while others did not. With this update, the configuration generation has been modified to deep copy messages before JSON parsing. As a result, all received logs now have structured messages included, even when they are forwarded to multiple destinations.(LOG-3767)

1.4.12. Logging 5.5.6

This release includes OpenShift Logging Bug Fix Release 5.5.6.

1.4.12.1. Bug fixes

  • Before this update, the Pod Security admission controller added the label podSecurityLabelSync = true to the openshift-logging namespace. This resulted in our specified security labels being overwritten, and as a result Collector pods would not start. With this update, the label podSecurityLabelSync = false preserves security labels. Collector pods deploy as expected. (LOG-3340)
  • Before this update, the Operator installed the console view plugin, even when it was not enabled on the cluster. This caused the Operator to crash. With this update, if an account for a cluster does not have the console view enabled, the Operator functions normally and does not install the console view. (LOG-3407)
  • Before this update, a prior fix to support a regression where the status of the Elasticsearch deployment was not being updated caused the Operator to crash unless the Red Hat Elasticsearch Operator was deployed. With this update, that fix has been reverted so the Operator is now stable but re-introduces the previous issue related to the reported status. (LOG-3428)
  • Before this update, the Loki Operator only deployed one replica of the LokiStack gateway regardless of the chosen stack size. With this update, the number of replicas is correctly configured according to the selected size. (LOG-3478)
  • Before this update, records written to Elasticsearch would fail if multiple label keys had the same prefix and some keys included dots. With this update, underscores replace dots in label keys, resolving the issue. (LOG-3341)
  • Before this update, the logging view plugin contained an incompatible feature for certain versions of OpenShift Container Platform. With this update, the correct release stream of the plugin resolves the issue. (LOG-3467)
  • Before this update, the reconciliation of the ClusterLogForwarder custom resource would incorrectly report a degraded status of one or more pipelines causing the collector pods to restart every 8-10 seconds. With this update, reconciliation of the ClusterLogForwarder custom resource processes correctly, resolving the issue. (LOG-3469)
  • Before this change the spec for the outputDefaults field of the ClusterLogForwarder custom resource would apply the settings to every declared Elasticsearch output type. This change corrects the behavior to match the enhancement specification where the setting specifically applies to the default managed Elasticsearch store. (LOG-3342)
  • Before this update, the OpenShift CLI (oc) must-gather script did not complete because the OpenShift CLI (oc) needs a folder with write permission to build its cache. With this update, the OpenShift CLI (oc) has write permissions to a folder, and the must-gather script completes successfully. (LOG-3472)
  • Before this update, the Loki Operator webhook server caused TLS errors. With this update, the Loki Operator webhook PKI is managed by the Operator Lifecycle Manager’s dynamic webhook management resolving the issue. (LOG-3511)

1.4.13.1. Bug fixes

  • Before this update, Kibana had a fixed 24h OAuth cookie expiration time, which resulted in 401 errors in Kibana whenever the accessTokenInactivityTimeout field was set to a value lower than 24h. With this update, Kibana’s OAuth cookie expiration time synchronizes to the accessTokenInactivityTimeout, with a default value of 24h. (LOG-3305)
  • Before this update, Vector parsed the message field when JSON parsing was enabled without also defining structuredTypeKey or structuredTypeName values. With this update, a value is required for either structuredTypeKey or structuredTypeName when writing structured logs to Elasticsearch. (LOG-3284)
  • Before this update, the FluentdQueueLengthIncreasing alert could fail to fire when there was a cardinality issue with the set of labels returned from this alert expression. This update reduces labels to only include those required for the alert. (LOG-3226)
  • Before this update, Loki did not have support to reach an external storage in a disconnected cluster. With this update, proxy environment variables and proxy trusted CA bundles are included in the container image to support these connections. (LOG-2860)
  • Before this update, OpenShift Container Platform web console users could not choose the ConfigMap object that includes the CA certificate for Loki, causing pods to operate without the CA. With this update, web console users can select the config map, resolving the issue. (LOG-3310)
  • Before this update, the CA key was used as volume name for mounting the CA into Loki, causing error states when the CA Key included non-conforming characters (such as dots). With this update, the volume name is standardized to an internal string which resolves the issue. (LOG-3332)

1.4.14.1. Bug fixes

  • Before this update, an error in the query parser of the logging view plugin caused parts of the logs query to disappear if the query contained curly brackets {}. This made the queries invalid, leading to errors being returned for valid queries. With this update, the parser correctly handles these queries. (LOG-3042)
  • Before this update, the Operator could enter a loop of removing and recreating the collector daemonset while the Elasticsearch or Kibana deployments changed their status. With this update, a fix in the status handling of the Operator resolves the issue. (LOG-3049)
  • Before this update, no alerts were implemented to support the collector implementation of Vector. This change adds Vector alerts and deploys separate alerts, depending upon the chosen collector implementation. (LOG-3127)
  • Before this update, the secret creation component of the Elasticsearch Operator modified internal secrets constantly. With this update, the existing secret is properly handled. (LOG-3138)
  • Before this update, a prior refactoring of the logging must-gather scripts removed the expected location for the artifacts. This update reverts that change to write artifacts to the /must-gather folder. (LOG-3213)
  • Before this update, on certain clusters, the Prometheus exporter would bind on IPv4 instead of IPv6. After this update, Fluentd detects the IP version and binds to 0.0.0.0 for IPv4 or [::] for IPv6. (LOG-3162)

1.4.14.2. CVEs

1.4.15. Logging 5.5.3

This release includes OpenShift Logging Bug Fix Release 5.5.3.

1.4.15.1. Bug fixes

  • Before this update, log entries that had structured messages included the original message field, which made the entry larger. This update removes the message field for structured logs to reduce the increased size. (LOG-2759)
  • Before this update, the collector configuration excluded logs from collector, default-log-store, and visualization pods, but was unable to exclude logs archived in a .gz file. With this update, archived logs stored as .gz files of collector, default-log-store, and visualization pods are also excluded. (LOG-2844)
  • Before this update, when requests to an unavailable pod were sent through the gateway, no alert would warn of the disruption. With this update, individual alerts will generate if the gateway has issues completing a write or read request. (LOG-2884)
  • Before this update, pod metadata could be altered by fluent plugins because the values passed through the pipeline by reference. This update ensures each log message receives a copy of the pod metadata so each message processes independently. (LOG-3046)
  • Before this update, selecting unknown severity in the OpenShift Console Logs view excluded logs with a level=unknown value. With this update, logs without level and with level=unknown values are visible when filtering by unknown severity. (LOG-3062)
  • Before this update, log records sent to Elasticsearch had an extra field named write-index that contained the name of the index to which the logs needed to be sent. This field is not a part of the data model. After this update, this field is no longer sent. (LOG-3075)
  • With the introduction of the new built-in Pod Security Admission Controller, Pods not configured in accordance with the enforced security standards defined globally or on the namespace level cannot run. With this update, the Operator and collectors allow privileged execution and run without security audit warnings or errors. (LOG-3077)
  • Before this update, the Operator removed any custom outputs defined in the ClusterLogForwarder custom resource when using LokiStack as the default log storage. With this update, the Operator merges custom outputs with the default outputs when processing the ClusterLogForwarder custom resource. (LOG-3095)

1.4.15.2. CVEs

1.4.16. Logging 5.5.2

This release includes OpenShift Logging Bug Fix Release 5.5.2.

1.4.16.1. Bug fixes

  • Before this update, alerting rules for the Fluentd collector did not adhere to the OpenShift Container Platform monitoring style guidelines. This update modifies those alerts to include the namespace label, resolving the issue. (LOG-1823)
  • Before this update, the index management rollover script failed to generate a new index name whenever there was more than one hyphen character in the name of the index. With this update, index names generate correctly. (LOG-2644)
  • Before this update, the Kibana route was setting a caCertificate value without a certificate present. With this update, no caCertificate value is set. (LOG-2661)
  • Before this update, a change in the collector dependencies caused it to issue a warning message for unused parameters. With this update, removing unused configuration parameters resolves the issue. (LOG-2859)
  • Before this update, pods created for deployments that Loki Operator created were mistakenly scheduled on nodes with non-Linux operating systems, if such nodes were available in the cluster the Operator was running in. With this update, the Operator attaches an additional node-selector to the pod definitions which only allows scheduling the pods on Linux-based nodes. (LOG-2895)
  • Before this update, the OpenShift Console Logs view did not filter logs by severity due to a LogQL parser issue in the LokiStack gateway. With this update, a parser fix resolves the issue and the OpenShift Console Logs view can filter by severity. (LOG-2908)
  • Before this update, a refactoring of the Fluentd collector plugins removed the timestamp field for events. This update restores the timestamp field, sourced from the event’s received time. (LOG-2923)
  • Before this update, absence of a level field in audit logs caused an error in vector logs. With this update, the addition of a level field in the audit log record resolves the issue. (LOG-2961)
  • Before this update, if you deleted the Kibana Custom Resource, the OpenShift Container Platform web console continued displaying a link to Kibana. With this update, removing the Kibana Custom Resource also removes that link. (LOG-3053)
  • Before this update, each rollover job created empty indices when the ClusterLogForwarder custom resource had JSON parsing defined. With this update, new indices are not empty. (LOG-3063)
  • Before this update, when the user deleted the LokiStack after an update to Loki Operator 5.5 resources originally created by Loki Operator 5.4 remained. With this update, the resources' owner-references point to the 5.5 LokiStack. (LOG-2945)
  • Before this update, a user was not able to view the application logs of namespaces they have access to. With this update, the Loki Operator automatically creates a cluster role and cluster role binding allowing users to read application logs. (LOG-2918)
  • Before this update, users with cluster-admin privileges were not able to properly view infrastructure and audit logs using the logging console. With this update, the authorization check has been extended to also recognize users in cluster-admin and dedicated-admin groups as admins. (LOG-2970)

1.4.16.2. CVEs

1.4.17. Logging 5.5.1

This release includes OpenShift Logging Bug Fix Release 5.5.1.

1.4.17.1. Enhancements

  • This enhancement adds an Aggregated Logs tab to the Pod Details page of the OpenShift Container Platform web console when the Logging Console Plug-in is in use. This enhancement is only available on OpenShift Container Platform 4.10 and later. (LOG-2647)
  • This enhancement adds Google Cloud Logging as an output option for log forwarding. (LOG-1482)

1.4.17.2. Bug fixes

  • Before this update, the Operator did not ensure that the pod was ready, which caused the cluster to reach an inoperable state during a cluster restart. With this update, the Operator marks new pods as ready before continuing to a new pod during a restart, which resolves the issue. (LOG-2745)
  • Before this update, Fluentd would sometimes not recognize that the Kubernetes platform rotated the log file and would no longer read log messages. This update corrects that by setting the configuration parameter suggested by the upstream development team. (LOG-2995)
  • Before this update, the addition of multi-line error detection caused internal routing to change and forward records to the wrong destination. With this update, the internal routing is correct. (LOG-2801)
  • Before this update, changing the OpenShift Container Platform web console’s refresh interval created an error when the Query field was empty. With this update, changing the interval is not an available option when the Query field is empty. (LOG-2917)

1.4.17.3. CVEs

1.4.18. Logging 5.5.0

This release includes:OpenShift Logging Bug Fix Release 5.5.0.

1.4.18.1. Enhancements

  • With this update, you can forward structured logs from different containers within the same pod to different indices. To use this feature, you must configure the pipeline with multi-container support and annotate the pods. (LOG-1296)
Important

JSON formatting of logs varies by application. Because creating too many indices impacts performance, limit your use of this feature to creating indices for logs that have incompatible JSON formats. Use queries to separate logs from different namespaces, or applications with compatible JSON formats.

  • With this update, you can filter logs with Elasticsearch outputs by using the Kubernetes common labels, app.kubernetes.io/component, app.kubernetes.io/managed-by, app.kubernetes.io/part-of, and app.kubernetes.io/version. Non-Elasticsearch output types can use all labels included in kubernetes.labels. (LOG-2388)
  • With this update, clusters with AWS Security Token Service (STS) enabled may use STS authentication to forward logs to Amazon CloudWatch. (LOG-1976)
  • With this update, the Loki Operator and Vector collector move from Technical Preview to General Availability. Full feature parity with prior releases are pending, and some APIs remain Technical Previews. See the Logging with the LokiStack section for details.

1.4.18.2. Bug fixes

  • Before this update, clusters configured to forward logs to Amazon CloudWatch wrote rejected log files to temporary storage, causing cluster instability over time. With this update, chunk backup for all storage options has been disabled, resolving the issue. (LOG-2746)
  • Before this update, the Operator was using versions of some APIs that are deprecated and planned for removal in future versions of OpenShift Container Platform. This update moves dependencies to the supported API versions. (LOG-2656)
  • Before this update, multiple ClusterLogForwarder pipelines configured for multiline error detection caused the collector to go into a crashloopbackoff error state. This update fixes the issue where multiple configuration sections had the same unique ID. (LOG-2241)
  • Before this update, the collector could not save non UTF-8 symbols to the Elasticsearch storage logs. With this update the collector encodes non UTF-8 symbols, resolving the issue. (LOG-2203)
  • Before this update, non-latin characters displayed incorrectly in Kibana. With this update, Kibana displays all valid UTF-8 symbols correctly. (LOG-2784)
