• Before this update, storage certificate names did not support dots. With this update, storage certificate name can contain dots. (TRACING-4348)
• Before this update, some users had to select a certificate when accessing the gateway route. With this update, there is no prompt to select a certificate. (TRACING-4431)
• Before this update, the gateway component was not scalable. With this update, the gateway component is scalable. (TRACING-4497)
• Before this update the Jaeger UI might fail with the 504 Gateway Time-out error when accessed via a route. With this update, users can specify route annotations for increasing timeout, such as haproxy.router.openshift.io/timeout: 3m, when querying large data sets. (TRACING-4511)

• Currently, the distributed tracing platform (Tempo) fails on the IBM Z (s390x) architecture. (TRACING-3545)

• Currently, Apache Spark is not supported.
• Currently, the streaming deployment via AMQ/Kafka is not supported on the IBM Z and IBM Power architectures.

• Before this update, secrets were perpetually generated on OpenShift Container Platform 4.16 because the operator tried to reconcile a new openshift.io/internal-registry-pull-secret-ref annotation for service accounts, causing a loop. With this update, the operator ignores this new annotation. (TRACING-4434)

• Currently, the distributed tracing platform (Tempo) fails on the IBM Z (s390x) architecture. (TRACING-3545)

• Currently, Apache Spark is not supported.

• Support for the Tempo monolithic deployment.

• Red Hat OpenShift distributed tracing platform (Tempo) 3.2 is based on the open source Grafana Tempo 2.4.1.
• Allowing the overriding of resources per component.

• Before this update, the Jaeger UI only displayed services that sent traces in the previous 15 minutes. With this update, the availability of the service and operation names can be configured by using the following field: spec.template.queryFrontend.jaegerQuery.servicesQueryDuration. (TRACING-3139)
• Before this update, the query-frontend pod might get stopped when out-of-memory (OOM) as a result of searching a large trace. With this update, resource limits can be set to prevent this issue. (TRACING-4009)

• Currently, the distributed tracing platform (Tempo) fails on the IBM Z (s390x) architecture. (TRACING-3545)

• Red Hat OpenShift distributed tracing platform (Jaeger) 3.2 is based on the open source Jaeger release 1.57.0.

• Currently, Apache Spark is not supported.
• Currently, the streaming deployment via AMQ/Kafka is not supported on the IBM Z and IBM Power architectures.

• Currently, when used with the Tempo Operator, the Jaeger UI only displays services that have sent traces in the last 15 minutes. For services that did not send traces in the last 15 minutes, traces are still stored but not displayed in the Jaeger UI. (TRACING-3139)
• Currently, the distributed tracing platform (Tempo) fails on the IBM Z (s390x) architecture. (TRACING-3545)

• Currently, Apache Spark is not supported.

• Support for TraceQL to Gateway component.

• Before this update, when a TempoStack instance was created with the monitorTab enabled in OpenShift Container Platform 4.15, the required tempo-redmetrics-cluster-monitoring-view ClusterRoleBinding was not created. This update resolves the issue by fixing the Operator RBAC for the monitor tab when the Operator is deployed in an arbitrary namespace. (TRACING-3786)
• Before this update, when a TempoStack instance was created on an OpenShift Container Platform cluster with only an IPv6 networking stack, the compactor and ingestor pods ran in the CrashLoopBackOff state, resulting in multiple errors. This update provides support for IPv6 clusters.(TRACING-3226)

• Currently, when used with the Tempo Operator, the Jaeger UI only displays services that have sent traces in the last 15 minutes. For services that did not send traces in the last 15 minutes, traces are still stored but not displayed in the Jaeger UI. (TRACING-3139)
• Currently, the distributed tracing platform (Tempo) fails on the IBM Z (s390x) architecture. (TRACING-3545)

• Red Hat OpenShift distributed tracing platform (Jaeger) 3.1 is based on the open source Jaeger release 1.53.0.

• Before this update, the connection target URL for the jaeger-agent container in the jager-query pod was overwritten with another namespace URL in OpenShift Container Platform 4.13. This was caused by a bug in the sidecar injection code in the jaeger-operator, causing nondeterministic jaeger-agent injection. With this update, the Operator prioritizes the Jaeger instance from the same namespace as the target deployment. (TRACING-3722)

• Currently, Apache Spark is not supported.
• Currently, the streaming deployment via AMQ/Kafka is not supported on the IBM Z and IBM Power architectures.

• Support for the ARM architecture.
• Support for cluster-wide proxy environments.

• Before this update, the Red Hat OpenShift distributed tracing platform (Jaeger) Operator used other images than relatedImages. This caused the ImagePullBackOff error in disconnected network environments when launching the jaeger pod because the oc adm catalog mirror command mirrors images specified in relatedImages. This update provides support for disconnected environments when using the oc adm catalog mirror CLI command. (TRACING-3546)

• Currently, Apache Spark is not supported.
• Currently, the streaming deployment via AMQ/Kafka is not supported on the IBM Z and IBM Power architectures.

• Support for the ARM architecture.
• Support for span request count, duration, and error count (RED) metrics. The metrics can be visualized in the Jaeger console deployed as part of Tempo or in the web console in the Observe menu.

• Before this update, the TempoStack CRD was not accepting custom CA certificate despite the option to choose CA certificates. This update fixes support for the custom TLS CA option for connecting to object storage. (TRACING-3462)
• Before this update, when mirroring the Red Hat OpenShift distributed tracing platform Operator images to a mirror registry for use in a disconnected cluster, the related Operator images for tempo, tempo-gateway, opa-openshift, and tempo-query were not mirrored. This update fixes support for disconnected environments when using the oc adm catalog mirror CLI command. (TRACING-3523)
• Before this update, the query frontend service of the Red Hat OpenShift distributed tracing platform was using internal mTLS when gateway was not deployed. This caused endpoint failure errors. This update fixes mTLS when Gateway is not deployed. (TRACING-3510)

• Currently, when used with the Tempo Operator, the Jaeger UI only displays services that have sent traces in the last 15 minutes. For services that did not send traces in the last 15 minutes, traces are still stored but not displayed in the Jaeger UI. (TRACING-3139)

• Currently, the distributed tracing platform (Tempo) fails on the IBM Z (s390x) architecture. (TRACING-3545)

• Currently, the Tempo query frontend service must not use internal mTLS when Gateway is not deployed. This issue does not affect the Jaeger Query API. The workaround is to disable mTLS. (TRACING-3510)

  Workaround

  Disable mTLS as follows:

  1. Open the Tempo Operator ConfigMap for editing by running the following command:

     $ oc edit configmap tempo-operator-manager-config -n openshift-tempo-operator 1

     1

     The project where the Tempo Operator is installed.

  2. Disable the mTLS in the Operator configuration by updating the YAML file:

     data:
       controller_manager_config.yaml: |
         featureGates:
           httpEncryption: false
           grpcEncryption: false
           builtInCertManagement:
             enabled: false

  3. Restart the Tempo Operator pod by running the following command:

     $ oc rollout restart deployment.apps/tempo-operator-controller -n openshift-tempo-operator

• Missing images for running the Tempo Operator in restricted environments. The Red Hat OpenShift distributed tracing platform (Tempo) CSV is missing references to the operand images. (TRACING-3523)

  Workaround

Prerequisites

• Monitoring for user-defined projects is enabled in the cluster.

Procedure

• Add the openshift.io/cluster-monitoring: "true" label in the project where the Tempo Operator is installed, which is openshift-tempo-operator by default.

Prerequisites

• The Red Hat OpenShift distributed tracing platform (Jaeger) Operator has been installed and verified.
• You have reviewed the instructions for how to customize the deployment.
• You have access to the OpenShift CLI (oc) that matches your OpenShift Container Platform version.
• You have access to the cluster as a user with the cluster-admin role.

Prerequisites

• The OpenShift Elasticsearch Operator has been installed.
• The Red Hat OpenShift distributed tracing platform (Jaeger) Operator has been installed.
• You have reviewed the instructions for how to customize the deployment.
• You have access to the OpenShift CLI (oc) that matches your OpenShift Container Platform version.
• You have access to the cluster as a user with the cluster-admin role.

Prerequisites

• The AMQ Streams Operator has been installed. If using version 1.4.0 or higher you can use self-provisioning. Otherwise you must create the Kafka instance.
• The Red Hat OpenShift distributed tracing platform (Jaeger) Operator has been installed.
• You have reviewed the instructions for how to customize the deployment.
• You have access to the OpenShift CLI (oc) that matches your OpenShift Container Platform version.
• You have access to the cluster as a user with the cluster-admin role.

• Red Hat OpenShift distributed tracing platform instance names must be unique. If you want to have multiple Red Hat OpenShift distributed tracing platform (Jaeger) instances and are using sidecar injected agents, then the Red Hat OpenShift distributed tracing platform (Jaeger) instances should have unique names, and the injection annotation should explicitly specify the Red Hat OpenShift distributed tracing platform (Jaeger) instance name the tracing data should be reported to.
• If you have a multitenant implementation and tenants are separated by namespaces, deploy a Red Hat OpenShift distributed tracing platform (Jaeger) instance to each tenant namespace.

• Probabilistic - The sampler makes a random sampling decision with the probability of sampling equal to the value of the sampling.param property. For example, using sampling.param=0.1 samples approximately 1 in 10 traces.
• Rate Limiting - The sampler uses a leaky bucket rate limiter to ensure that traces are sampled with a certain constant rate. For example, using sampling.param=2.0 samples requests with the rate of 2 traces per second.

• logging.openshift.io/elasticsearch-cert-management: "true"
