Abstract

Offers cluster administrators tools for gathering data for your cluster, monitoring, and troubleshooting.

Chapter 1. Support overview

Red Hat offers cluster administrators tools for gathering data for your cluster, monitoring, and troubleshooting.

1.1. Get support

Get support: Visit the Red Hat Customer Portal to review knowledge base articles, submit a support case, and review additional product documentation and resources.

1.2. Remote health monitoring issues

Remote health monitoring issues: OpenShift Dedicated collects telemetry and configuration data about your cluster and reports it to Red Hat by using the Telemeter Client and the Insights Operator. Red Hat uses this data to understand and resolve issues in connected cluster. OpenShift Dedicated collects data and monitors health using the following:

Telemetry: The Telemetry Client gathers and uploads the metrics values to Red Hat every four minutes and thirty seconds. Red Hat uses this data to:
- Monitor the clusters.
- Roll out OpenShift Dedicated upgrades.
- Improve the upgrade experience.
Insight Operator: By default, OpenShift Dedicated installs and enables the Insight Operator, which reports configuration and component failure status every two hours. The Insight Operator helps to:
- Identify potential cluster issues proactively.
- Provide a solution and preventive action in Red Hat OpenShift Cluster Manager.

You can review telemetry information.

If you have enabled remote health reporting, Use Insights to identify issues. You can optionally disable remote health reporting.

1.3. Troubleshooting issues

A cluster administrator can monitor and troubleshoot the following OpenShift Dedicated component issues:

Node issues: A cluster administrator can verify and troubleshoot node-related issues by reviewing the status, resource usage, and configuration of a node. You can query the following:
- Kubelet’s status on a node.
- Cluster node journal logs.
Operator issues: A cluster administrator can do the following to resolve Operator issues:
- Verify Operator subscription status.
- Check Operator pod health.
- Gather Operator logs.
Pod issues: A cluster administrator can troubleshoot pod-related issues by reviewing the status of a pod and completing the following:
- Review pod and container logs.
- Start debug pods with root access.
Storage issues: A multi-attach storage error occurs when the mounting volume on a new node is not possible because the failed node cannot unmount the attached volume. A cluster administrator can do the following to resolve multi-attach storage issues:
- Enable multiple attachments by using RWX volumes.
- Recover or delete the failed node when using an RWO volume.
Monitoring issues: A cluster administrator can follow the procedures on the troubleshooting page for monitoring. If the metrics for your user-defined projects are unavailable or if Prometheus is consuming a lot of disk space, check the following:
- Investigate why user-defined metrics are unavailable.
- Determine why Prometheus is consuming a lot of disk space.

OpenShift CLI (oc) issues: Investigate OpenShift CLI (oc) issues by increasing the log level.

Chapter 2. Managing your cluster resources

You can apply global configuration options in OpenShift Dedicated. Operators apply these configuration settings across the cluster.

2.1. Interacting with your cluster resources

You can interact with cluster resources by using the OpenShift CLI (oc) tool in OpenShift Dedicated. The cluster resources that you see after running the oc api-resources command can be edited.

Prerequisites

You have access to the cluster as a user with the dedicated-admin role.
You have access to the web console or you have installed the oc CLI tool.

Procedure

To see which configuration Operators have been applied, run the following command:
```
$ oc api-resources -o name | grep config.openshift.io
```
To see what cluster resources you can configure, run the following command:
```
$ oc explain <resource_name>.config.openshift.io
```
To see the configuration of custom resource definition (CRD) objects in the cluster, run the following command:
```
$ oc get <resource_name>.config -o yaml
```
To edit the cluster resource configuration, run the following command:
```
$ oc edit <resource_name>.config -o yaml
```

Chapter 4. Remote health monitoring with connected clusters

4.1. About remote health monitoring

OpenShift Dedicated collects telemetry and configuration data about your cluster and reports it to Red Hat by using the Telemeter Client and the Insights Operator. The data that is provided to Red Hat enables the benefits outlined in this document.

A cluster that reports data to Red Hat through Telemetry and the Insights Operator is considered a connected cluster.

Telemetry is the term that Red Hat uses to describe the information being sent to Red Hat by the OpenShift Dedicated Telemeter Client. Lightweight attributes are sent from connected clusters to Red Hat to enable subscription management automation, monitor the health of clusters, assist with support, and improve customer experience.

The Insights Operator gathers OpenShift Dedicated configuration data and sends it to Red Hat. The data is used to produce insights about potential issues that a cluster might be exposed to. These insights are communicated to cluster administrators on OpenShift Cluster Manager.

More information is provided in this document about these two processes.

Telemetry and Insights Operator benefits

Telemetry and the Insights Operator enable the following benefits for end-users:

Enhanced identification and resolution of issues. Events that might seem normal to an end-user can be observed by Red Hat from a broader perspective across a fleet of clusters. Some issues can be more rapidly identified from this point of view and resolved without an end-user needing to open a support case or file a Jira issue.
Advanced release management. OpenShift Dedicated offers the candidate, fast, and stable release channels, which enable you to choose an update strategy. The graduation of a release from fast to stable is dependent on the success rate of updates and on the events seen during upgrades. With the information provided by connected clusters, Red Hat can improve the quality of releases to stable channels and react more rapidly to issues found in the fast channels.
Targeted prioritization of new features and functionality. The data collected provides insights about which areas of OpenShift Dedicated are used most. With this information, Red Hat can focus on developing the new features and functionality that have the greatest impact for our customers.
A streamlined support experience. You can provide a cluster ID for a connected cluster when creating a support ticket on the Red Hat Customer Portal. This enables Red Hat to deliver a streamlined support experience that is specific to your cluster, by using the connected information. This document provides more information about that enhanced support experience.
Predictive analytics. The insights displayed for your cluster on OpenShift Cluster Manager are enabled by the information collected from connected clusters. Red Hat is investing in applying deep learning, machine learning, and artificial intelligence automation to help identify issues that OpenShift Dedicated clusters are exposed to.

On OpenShift Dedicated, remote health reporting is always enabled. You cannot opt out of it.

4.1.1. About Telemetry

Telemetry sends a carefully chosen subset of the cluster monitoring metrics to Red Hat. The Telemeter Client fetches the metrics values every four minutes and thirty seconds and uploads the data to Red Hat. These metrics are described in this document.

This stream of data is used by Red Hat to monitor the clusters in real-time and to react as necessary to problems that impact our customers. It also allows Red Hat to roll out OpenShift Dedicated upgrades to customers to minimize service impact and continuously improve the upgrade experience.

This debugging information is available to Red Hat Support and Engineering teams with the same restrictions as accessing data reported through support cases. All connected cluster information is used by Red Hat to help make OpenShift Dedicated better and more intuitive to use.

4.1.1.1. Information collected by Telemetry

The following information is collected by Telemetry:

4.1.1.1.1. System information

Version information, including the OpenShift Dedicated cluster version and installed update details that are used to determine update version availability
Update information, including the number of updates available per cluster, the channel and image repository used for an update, update progress information, and the number of errors that occur in an update
The unique random identifier that is generated during an installation
Configuration details that help Red Hat Support to provide beneficial support for customers, including node configuration at the cloud infrastructure level, hostnames, IP addresses, Kubernetes pod names, namespaces, and services
The OpenShift Dedicated framework components installed in a cluster and their condition and status
Events for all namespaces listed as "related objects" for a degraded Operator
Information about degraded software
Information about the validity of certificates
The name of the provider platform that OpenShift Dedicated is deployed on and the data center location

4.1.1.1.2. Sizing Information

Sizing information about clusters, machine types, and machines, including the number of CPU cores and the amount of RAM used for each
The number of etcd members and the number of objects stored in the etcd cluster

4.1.1.1.3. Usage information

Usage information about components, features, and extensions
Usage details about Technology Previews and unsupported configurations

Telemetry does not collect identifying information such as usernames or passwords. Red Hat does not intend to collect personal information. If Red Hat discovers that personal information has been inadvertently received, Red Hat will delete such information. To the extent that any telemetry data constitutes personal data, please refer to the Red Hat Privacy Statement for more information about Red Hat’s privacy practices.

4.1.1.2. User Telemetry

Red Hat collects anonymized user data from your browser. This anonymized data includes what pages, features, and resource types that the user of all clusters with enabled telemetry uses.

Other considerations:

User events are grouped as a SHA-1 hash.
User’s IP address is saved as 0.0.0.0.
User names and IP addresses are never saved as separate values.

Additional resources

See Showing data collected by Telemetry for details about how to list the attributes that Telemetry gathers from Prometheus in OpenShift Dedicated.
See the upstream cluster-monitoring-operator source code for a list of the attributes that Telemetry gathers from Prometheus.

4.1.2. About the Insights Operator

Users of OpenShift Dedicated can display the report of each cluster in the Insights Advisor service on Red Hat Hybrid Cloud Console. If any issues have been identified, Insights provides further details and, if available, steps on how to solve a problem.

The Insights Operator does not collect identifying information, such as user names, passwords, or certificates. See Red Hat Insights Data & Application Security for information about Red Hat Insights data collection and controls.

Red Hat uses all connected cluster information to:

Identify potential cluster issues and provide a solution and preventive actions in the Insights Advisor service on Red Hat Hybrid Cloud Console
Improve OpenShift Dedicated by providing aggregated and critical information to product and support teams
Make OpenShift Dedicated more intuitive

4.1.2.1. Information collected by the Insights Operator

The following information is collected by the Insights Operator:

General information about your cluster and its components to identify issues that are specific to your OpenShift Dedicated version and environment
Configuration files, such as the image registry configuration, of your cluster to determine incorrect settings and issues that are specific to parameters you set
Errors that occur in the cluster components
Progress information of running updates, and the status of any component upgrades
Details of the platform that OpenShift Dedicated is deployed on and the region that the cluster is located in
If an Operator reports an issue, information is collected about core OpenShift Dedicated pods in the openshift-* and kube-* projects. This includes state, resource, security context, volume information, and more

Additional resources

The Insights Operator source code is available for review and contribution. See the Insights Operator upstream project for a list of the items collected by the Insights Operator.

4.1.3. Understanding Telemetry and Insights Operator data flow

The Telemeter Client collects selected time series data from the Prometheus API. The time series data is uploaded to api.openshift.com every four minutes and thirty seconds for processing.

The Insights Operator gathers selected data from the Kubernetes API and the Prometheus API into an archive. The archive is uploaded to OpenShift Cluster Manager every two hours for processing. The Insights Operator also downloads the latest Insights analysis from OpenShift Cluster Manager. This is used to populate the Insights status pop-up that is included in the Overview page in the OpenShift Dedicated web console.

All of the communication with Red Hat occurs over encrypted channels by using Transport Layer Security (TLS) and mutual certificate authentication. All of the data is encrypted in transit and at rest.

Access to the systems that handle customer data is controlled through multi-factor authentication and strict authorization controls. Access is granted on a need-to-know basis and is limited to required operations.

4.3. Using Insights to identify issues with your cluster

Insights repeatedly analyzes the data Insights Operator sends. Users of OpenShift Dedicated can display the report in the Insights Advisor service on Red Hat Hybrid Cloud Console.

4.3.1. About Red Hat Insights Advisor for OpenShift Dedicated

You can use Insights Advisor to assess and monitor the health of your OpenShift Dedicated clusters. Whether you are concerned about individual clusters, or with your whole infrastructure, it is important to be aware of the exposure of your cluster infrastructure to issues that can affect service availability, fault tolerance, performance, or security.

Using cluster data collected by the Insights Operator, Insights repeatedly compares that data against a library of recommendations. Each recommendation is a set of cluster-environment conditions that can leave OpenShift Dedicated clusters at risk. The results of the Insights analysis are available in the Insights Advisor service on Red Hat Hybrid Cloud Console. In the Console, you can perform the following actions:

See clusters impacted by a specific recommendation.
Use robust filtering capabilities to refine your results to those recommendations.
Learn more about individual recommendations, details about the risks they present, and get resolutions tailored to your individual clusters.
Share results with other stakeholders.

4.3.2. Understanding Insights Advisor recommendations

Insights Advisor bundles information about various cluster states and component configurations that can negatively affect the service availability, fault tolerance, performance, or security of your clusters. This information set is called a recommendation in Insights Advisor and includes the following information:

Name: A concise description of the recommendation
Added: When the recommendation was published to the Insights Advisor archive
Category: Whether the issue has the potential to negatively affect service availability, fault tolerance, performance, or security
Total risk: A value derived from the likelihood that the condition will negatively affect your infrastructure, and the impact on operations if that were to happen
Clusters: A list of clusters on which a recommendation is detected
Description: A brief synopsis of the issue, including how it affects your clusters
Link to associated topics: More information from Red Hat about the issue

4.3.3. Displaying potential issues with your cluster

This section describes how to display the Insights report in Insights Advisor on OpenShift Cluster Manager.

Note that Insights repeatedly analyzes your cluster and shows the latest results. These results can change, for example, if you fix an issue or a new issue has been detected.

Prerequisites

Your cluster is registered on OpenShift Cluster Manager.
Remote health reporting is enabled, which is the default.
You are logged in to OpenShift Cluster Manager.

Procedure

Navigate to Advisor → Recommendations on OpenShift Cluster Manager.
Depending on the result, Insights Advisor displays one of the following:
- No matching recommendations found, if Insights did not identify any issues.
- A list of issues Insights has detected, grouped by risk (low, moderate, important, and critical).
- No clusters yet, if Insights has not yet analyzed the cluster. The analysis starts shortly after the cluster has been installed, registered, and connected to the internet.
If any issues are displayed, click the > icon in front of the entry for more details.
Depending on the issue, the details can also contain a link to more information from Red Hat about the issue.

4.3.4. Displaying all Insights Advisor recommendations

The Recommendations view, by default, only displays the recommendations that are detected on your clusters. However, you can view all of the recommendations in the advisor archive.

Prerequisites

Remote health reporting is enabled, which is the default.
Your cluster is registered on Red Hat Hybrid Cloud Console.
You are logged in to OpenShift Cluster Manager.

Procedure

Navigate to Advisor → Recommendations on OpenShift Cluster Manager.
Click the X icons next to the Clusters Impacted and Status filters.
You can now browse through all of the potential recommendations for your cluster.

4.3.5. Advisor recommendation filters

The Insights advisor service can return a large number of recommendations. To focus on your most critical recommendations, you can apply filters to the Advisor recommendations list to remove low-priority recommendations.

By default, filters are set to only show enabled recommendations that are impacting one or more clusters. To view all or disabled recommendations in the Insights library, you can customize the filters.

To apply a filter, select a filter type and then set its value based on the options that are available in the drop-down list. You can apply multiple filters to the list of recommendations.

You can set the following filter types:

Name: Search for a recommendation by name.
Total risk: Select one or more values from Critical, Important, Moderate, and Low indicating the likelihood and the severity of a negative impact on a cluster.
Impact: Select one or more values from Critical, High, Medium, and Low indicating the potential impact to the continuity of cluster operations.
Likelihood: Select one or more values from Critical, High, Medium, and Low indicating the potential for a negative impact to a cluster if the recommendation comes to fruition.
Category: Select one or more categories from Service Availability, Performance, Fault Tolerance, Security, and Best Practice to focus your attention on.
Status: Click a radio button to show enabled recommendations (default), disabled recommendations, or all recommendations.
Clusters impacted: Set the filter to show recommendations currently impacting one or more clusters, non-impacting recommendations, or all recommendations.
Risk of change: Select one or more values from High, Moderate, Low, and Very low indicating the risk that the implementation of the resolution could have on cluster operations.

4.3.5.1. Filtering Insights advisor recommendations

As an OpenShift Dedicated cluster manager, you can filter the recommendations that are displayed on the recommendations list. By applying filters, you can reduce the number of reported recommendations and concentrate on your highest priority recommendations.

The following procedure demonstrates how to set and remove Category filters; however, the procedure is applicable to any of the filter types and respective values.

Prerequisites

You are logged in to the OpenShift Cluster Manager Hybrid Cloud Console.

Procedure

Go to Red Hat Hybrid Cloud Console → OpenShift → Advisor recommendations.
In the main, filter-type drop-down list, select the Category filter type.
Expand the filter-value drop-down list and select the checkbox next to each category of recommendation you want to view. Leave the checkboxes for unnecessary categories clear.
Optional: Add additional filters to further refine the list.

Only recommendations from the selected categories are shown in the list.

Verification

After applying filters, you can view the updated recommendations list. The applied filters are added next to the default filters.

4.3.5.2. Removing filters from Insights Advisor recommendations

You can apply multiple filters to the list of recommendations. When ready, you can remove them individually or completely reset them.

Removing filters individually

Click the X icon next to each filter, including the default filters, to remove them individually.

Removing all non-default filters

Click Reset filters to remove only the filters that you applied, leaving the default filters in place.

4.3.6. Disabling Insights Advisor recommendations

You can disable specific recommendations that affect your clusters, so that they no longer appear in your reports. It is possible to disable a recommendation for a single cluster or all of your clusters.

Note

Disabling a recommendation for all of your clusters also applies to any future clusters.

Prerequisites

Remote health reporting is enabled, which is the default.
Your cluster is registered on OpenShift Cluster Manager.
You are logged in to OpenShift Cluster Manager.

Procedure

Navigate to Advisor → Recommendations on OpenShift Cluster Manager.
Optional: Use the Clusters Impacted and Status filters as needed.
Disable an alert by using one of the following methods:
- To disable an alert:
  1. Click the Options menu for that alert, and then click Disable recommendation.
  2. Enter a justification note and click Save.
- To view the clusters affected by this alert before disabling the alert:
  1. Click the name of the recommendation to disable. You are directed to the single recommendation page.
  2. Review the list of clusters in the Affected clusters section.
  3. Click Actions → Disable recommendation to disable the alert for all of your clusters.
  4. Enter a justification note and click Save.

4.3.7. Enabling a previously disabled Insights Advisor recommendation

When a recommendation is disabled for all clusters, you no longer see the recommendation in the Insights Advisor. You can change this behavior.

Prerequisites

Remote health reporting is enabled, which is the default.
Your cluster is registered on OpenShift Cluster Manager.
You are logged in to OpenShift Cluster Manager.

Procedure

Navigate to Advisor → Recommendations on OpenShift Cluster Manager.
Filter the recommendations to display on the disabled recommendations:
1. From the Status drop-down menu, select Status.
2. From the Filter by status drop-down menu, select Disabled.
3. Optional: Clear the Clusters impacted filter.
Locate the recommendation to enable.
Click the Options menu , and then click Enable recommendation.

4.3.8. Displaying the Insights status in the web console

Insights repeatedly analyzes your cluster and you can display the status of identified potential issues of your cluster in the OpenShift Dedicated web console. This status shows the number of issues in the different categories and, for further details, links to the reports in OpenShift Cluster Manager.

Prerequisites

Your cluster is registered in OpenShift Cluster Manager.
Remote health reporting is enabled, which is the default.
You are logged in to the OpenShift Dedicated web console.

Procedure

Navigate to Home → Overview in the OpenShift Dedicated web console.
Click Insights on the Status card.
The pop-up window lists potential issues grouped by risk. Click the individual categories or View all recommendations in Insights Advisor to display more details.

4.4. Using the Insights Operator

The Insights Operator periodically gathers configuration and component failure status and, by default, reports that data every two hours to Red Hat. This information enables Red Hat to assess configuration and deeper failure data than is reported through Telemetry. Users of OpenShift Dedicated can display the report in the Insights Advisor service on Red Hat Hybrid Cloud Console.

Additional resources

For more information on using Insights Advisor to identify issues with your cluster, see Using Insights to identify issues with your cluster.

4.4.1. Understanding Insights Operator alerts

The Insights Operator declares alerts through the Prometheus monitoring system to the Alertmanager. You can view these alerts in the Alerting UI in the OpenShift Dedicated web console by using one of the following methods:

In the Administrator perspective, click Observe → Alerting.
In the Developer perspective, click Observe → <project_name> → Alerts tab.

Currently, Insights Operator sends the following alerts when the conditions are met:

Table 4.1. Insights Operator alerts
Alert	Description
`InsightsDisabled`	Insights Operator is disabled.
`SimpleContentAccessNotAvailable`	Simple content access is not enabled in Red Hat Subscription Management.
`InsightsRecommendationActive`	Insights has an active recommendation for the cluster.

4.4.2. Obfuscating Deployment Validation Operator data

Cluster administrators can configure the Insight Operator to obfuscate data from the Deployment Validation Operator (DVO), if the Operator is installed. When the workload_names value is added to the insights-config ConfigMap object, workload names—rather than UIDs—are displayed in Insights for Openshift, making them more recognizable for cluster administrators.

Prerequisites

Remote health reporting is enabled, which is the default.
You are logged in to the OpenShift Dedicated web console with the "cluster-admin" role.
The insights-config ConfigMap object exists in the openshift-insights namespace.
The cluster is self managed and the Deployment Validation Operator is installed.

Procedure

Go to Workloads → ConfigMaps and select Project: openshift-insights.
Click on the insights-config ConfigMap object to open it.
Click Actions and select Edit ConfigMap.
Click the YAML view radio button.

In the file, set the obfuscation attribute with the workload_names value.

apiVersion: v1
kind: ConfigMap
# ...
data:
  config.yaml: |
    dataReporting:
      obfuscation:
        - workload_names
# ...

Click Save. The insights-config config-map details page opens.
Verify that the value of the config.yaml obfuscation attribute is set to - workload_names.

Chapter 5. Gathering data about your cluster

You can use the following tools to get debugging information about your OpenShift Dedicated cluster.

5.1. About the must-gather tool

The oc adm must-gather CLI command collects the information from your cluster that is most likely needed for debugging issues, including:

Resource definitions
Service logs

By default, the oc adm must-gather command uses the default plugin image and writes into ./must-gather.local.

Alternatively, you can collect specific information by running the command with the appropriate arguments as described in the following sections:

To collect data related to one or more specific features, use the --image argument with an image, as listed in a following section.
For example:
```
$ oc adm must-gather \
  --image=registry.redhat.io/container-native-virtualization/cnv-must-gather-rhel9:v4.17.2
```
To collect the audit logs, use the -- /usr/bin/gather_audit_logs argument, as described in a following section.
For example:
```
$ oc adm must-gather -- /usr/bin/gather_audit_logs
```
Note
Audit logs are not collected as part of the default set of information to reduce the size of the files.

When you run oc adm must-gather, a new pod with a random name is created in a new project on the cluster. The data is collected on that pod and saved in a new directory that starts with must-gather.local in the current working directory.

For example:

NAMESPACE                      NAME                 READY   STATUS      RESTARTS      AGE
...
openshift-must-gather-5drcj    must-gather-bklx4    2/2     Running     0             72s
openshift-must-gather-5drcj    must-gather-s8sdh    2/2     Running     0             72s
...

Optionally, you can run the oc adm must-gather command in a specific namespace by using the --run-namespace option.

For example:

$ oc adm must-gather --run-namespace <namespace> \
  --image=registry.redhat.io/container-native-virtualization/cnv-must-gather-rhel9:v4.17.2

5.1.1. Gathering data about your cluster for Red Hat Support

You can gather debugging information about your cluster by using the oc adm must-gather CLI command.

Prerequisites

You have access to the cluster as a user with the cluster-admin role.
Note
In OpenShift Dedicated deployments, customers who are not using the Customer Cloud Subscription (CCS) model cannot use the oc adm must-gather command as it requires cluster-admin privileges.
The OpenShift CLI (oc) is installed.

Procedure

Navigate to the directory where you want to store the must-gather data.
Run the oc adm must-gather command:
```
$ oc adm must-gather
```
Note
Because this command picks a random control plane node by default, the pod might be scheduled to a control plane node that is in the NotReady and SchedulingDisabled state.
1. If this command fails, for example, if you cannot schedule a pod on your cluster, then use the oc adm inspect command to gather information for particular resources.
  Note
  Contact Red Hat Support for the recommended resources to gather.
Create a compressed file from the must-gather directory that was just created in your working directory. For example, on a computer that uses a Linux operating system, run the following command:
```
$ tar cvaf must-gather.tar.gz must-gather.local.5421342344627712289/ 1
```
1
Make sure to replace must-gather-local.5421342344627712289/ with the actual directory name.
Attach the compressed file to your support case on the the Customer Support page of the Red Hat Customer Portal.

5.1.2. Must-gather flags

The flags listed in the following table are available to use with the oc adm must-gather command.

Table 5.1. OpenShift Dedicated flags for oc adm must-gather
Flag	Example command	Description

Note

To determine the latest version for an OpenShift Dedicated component’s image, see the OpenShift Operator Life Cycles web page on the Red Hat Customer Portal.

Prerequisites

You have access to the cluster as a user with the cluster-admin role.
The OpenShift CLI (oc) is installed.

Procedure

Navigate to the directory where you want to store the must-gather data.

Run the oc adm must-gather command with one or more --image or --image-stream arguments.

Note

To collect the default must-gather data in addition to specific feature data, add the --image-stream=openshift/must-gather argument.

For example, the following command gathers both the default cluster data and information specific to OpenShift Virtualization:

$ oc adm must-gather \
  --image-stream=openshift/must-gather \ 1
  --image=registry.redhat.io/container-native-virtualization/cnv-must-gather-rhel9:v4.17.2 2

1: The default OpenShift Dedicated must-gather image
2: The must-gather image for OpenShift Virtualization

You can use the must-gather tool with additional arguments to gather data that is specifically related to OpenShift Logging and the Cluster Logging Operator in your cluster. For OpenShift Logging, run the following command:

$ oc adm must-gather --image=$(oc -n openshift-logging get deployment.apps/cluster-logging-operator \
  -o jsonpath='{.spec.template.spec.containers[?(@.name == "cluster-logging-operator")].image}')

Run the oc adm must-gather command with one or more --image or --image-stream arguments. For example, the following command gathers both the default cluster data and information specific to KubeVirt:
```
$ oc adm must-gather \
 --image-stream=openshift/must-gather \ 1
 --image=quay.io/kubevirt/must-gather 2
```
1
The default OpenShift Dedicated must-gather image
2
The must-gather image for KubeVirt
Create a compressed file from the must-gather directory that was just created in your working directory. For example, on a computer that uses a Linux operating system, run the following command:
```
$ tar cvaf must-gather.tar.gz must-gather.local.5421342344627712289/ 1
```
1
Make sure to replace must-gather-local.5421342344627712289/ with the actual directory name.
Attach the compressed file to your support case on the the Customer Support page of the Red Hat Customer Portal.

OpenShift Dedicated update life cycle

5.2.1. Gathering network logs

You can gather network logs on all nodes in a cluster.

Procedure

Run the oc adm must-gather command with -- gather_network_logs:
```
$ oc adm must-gather -- gather_network_logs
```
Note
By default, the must-gather tool collects the OVN nbdb and sbdb databases from all of the nodes in the cluster. Adding the -- gather_network_logs option to include additional logs that contain OVN-Kubernetes transactions for OVN nbdb database.
Create a compressed file from the must-gather directory that was just created in your working directory. For example, on a computer that uses a Linux operating system, run the following command:
```
$ tar cvaf must-gather.tar.gz must-gather.local.472290403699006248 1
```
1
Replace must-gather-local.472290403699006248 with the actual directory name.
Attach the compressed file to your support case on the the Customer Support page of the Red Hat Customer Portal.

5.2.2. Changing the must-gather storage limit

When using the oc adm must-gather command to collect data the default maximum storage for the information is 30% of the storage capacity of the container. After the 30% limit is reached the container is killed and the gathering process stops. Information already gathered is downloaded to your local storage. To run the must-gather command again, you need either a container with more storage capacity or to adjust the maximum volume percentage.

If the container reaches the storage limit, an error message similar to the following example is generated.

Example output

Disk usage exceeds the volume percentage of 30% for mounted directory. Exiting...

Prerequisites

You have access to the cluster as a user with the cluster-admin role.
The OpenShift CLI (oc) is installed.

Procedure

Run the oc adm must-gather command with the volume-percentage flag. The new value cannot exceed 100.
```
$ oc adm must-gather --volume-percentage <storage_percentage>
```

5.3. Obtaining your cluster ID

When providing information to Red Hat Support, it is helpful to provide the unique identifier for your cluster. You can have your cluster ID autofilled by using the OpenShift Dedicated web console. You can also manually obtain your cluster ID by using the web console or the OpenShift CLI (oc).

Prerequisites

You have access to the cluster as a user with the dedicated-admin role.
You have access to the web console or the OpenShift CLI (oc) installed.

Procedure

To manually obtain your cluster ID using OpenShift Cluster Manager:
1. Navigate to Cluster List.
2. Click on the name of the cluster you need to open a support case for.
3. Find the value in the Cluster ID field of the Details section of the Overview tab.
To open a support case and have your cluster ID autofilled using the web console:
1. From the toolbar, navigate to (?) Help and select Share Feedback from the list.
2. Click Open a support case from the Tell us about your experience window.
To manually obtain your cluster ID using the web console:
1. Navigate to Home → Overview.
2. The value is available in the Cluster ID field of the Details section.
To obtain your cluster ID using the OpenShift CLI (oc), run the following command:
```
$ oc get clusterversion -o jsonpath='{.items[].spec.clusterID}{"\n"}'
```

5.4. Querying cluster node journal logs

You can gather journald unit logs and other logs within /var/log on individual cluster nodes.

Prerequisites

You have access to the cluster as a user with the cluster-admin role.
Note
In OpenShift Dedicated deployments, customers who are not using the Customer Cloud Subscription (CCS) model cannot use the oc adm node-logs command as it requires cluster-admin privileges.
You have installed the OpenShift CLI (oc).

Procedure

Query kubelet journald unit logs from OpenShift Dedicated cluster nodes. The following example queries control plane nodes only:
```
$ oc adm node-logs --role=master -u kubelet  1
```
1
Replace kubelet as appropriate to query other unit logs.
Collect logs from specific subdirectories under /var/log/ on cluster nodes.
1. Retrieve a list of logs contained within a /var/log/ subdirectory. The following example lists files in /var/log/openshift-apiserver/ on all control plane nodes:
```
$ oc adm node-logs --role=master --path=openshift-apiserver
```
2. Inspect a specific log within a /var/log/ subdirectory. The following example outputs /var/log/openshift-apiserver/audit.log contents from all control plane nodes:
```
$ oc adm node-logs --role=master --path=openshift-apiserver/audit.log
```

5.5. Network trace methods

Collecting network traces, in the form of packet capture records, can assist Red Hat Support with troubleshooting network issues.

OpenShift Dedicated supports two ways of performing a network trace. Review the following table and choose the method that meets your needs.

Table 5.3. Supported methods of collecting a network trace
Method	Benefits and capabilities
Collecting a host network trace	You perform a packet capture for a duration that you specify on one or more nodes at the same time. The packet capture files are transferred from nodes to the client machine when the specified duration is met. You can troubleshoot why a specific action triggers network communication issues. Run the packet capture, perform the action that triggers the issue, and use the logs to diagnose the issue.
Collecting a network trace from an OpenShift Dedicated node or container	You perform a packet capture on one node or one container. You run the `tcpdump` command interactively, so you can control the duration of the packet capture. You can start the packet capture manually, trigger the network communication issue, and then stop the packet capture manually. This method uses the `cat` command and shell redirection to copy the packet capture data from the node or container to the client machine.

5.5.1. Collecting a host network trace

Sometimes, troubleshooting a network-related issue is simplified by tracing network communication and capturing packets on multiple nodes at the same time.

You can use a combination of the oc adm must-gather command and the registry.redhat.io/openshift4/network-tools-rhel8 container image to gather packet captures from nodes. Analyzing packet captures can help you troubleshoot network communication issues.

The oc adm must-gather command is used to run the tcpdump command in pods on specific nodes. The tcpdump command records the packet captures in the pods. When the tcpdump command exits, the oc adm must-gather command transfers the files with the packet captures from the pods to your client machine.

Tip

The sample command in the following procedure demonstrates performing a packet capture with the tcpdump command. However, you can run any command in the container image that is specified in the --image argument to gather troubleshooting information from multiple nodes at the same time.

Prerequisites

You are logged in to OpenShift Dedicated as a user with the cluster-admin role.
Note
In OpenShift Dedicated deployments, customers who are not using the Customer Cloud Subscription (CCS) model cannot use the oc adm must-gather command as it requires cluster-admin privileges.
You have installed the OpenShift CLI (oc).

Procedure

Run a packet capture from the host network on some nodes by running the following command:
```
$ oc adm must-gather \
    --dest-dir /tmp/captures \  <.>
    --source-dir '/tmp/tcpdump/' \  <.>
    --image registry.redhat.io/openshift4/network-tools-rhel8:latest \  <.>
    --node-selector 'node-role.kubernetes.io/worker' \  <.>
    --host-network=true \  <.>
    --timeout 30s \  <.>
    -- \
    tcpdump -i any \  <.>
    -w /tmp/tcpdump/%Y-%m-%dT%H:%M:%S.pcap -W 1 -G 300
```
<.> The --dest-dir argument specifies that oc adm must-gather stores the packet captures in directories that are relative to /tmp/captures on the client machine. You can specify any writable directory. <.> When tcpdump is run in the debug pod that oc adm must-gather starts, the --source-dir argument specifies that the packet captures are temporarily stored in the /tmp/tcpdump directory on the pod. <.> The --image argument specifies a container image that includes the tcpdump command. <.> The --node-selector argument and example value specifies to perform the packet captures on the worker nodes. As an alternative, you can specify the --node-name argument instead to run the packet capture on a single node. If you omit both the --node-selector and the --node-name argument, the packet captures are performed on all nodes. <.> The --host-network=true argument is required so that the packet captures are performed on the network interfaces of the node. <.> The --timeout argument and value specify to run the debug pod for 30 seconds. If you do not specify the --timeout argument and a duration, the debug pod runs for 10 minutes. <.> The -i any argument for the tcpdump command specifies to capture packets on all network interfaces. As an alternative, you can specify a network interface name.
Perform the action, such as accessing a web application, that triggers the network communication issue while the network trace captures packets.

Review the packet capture files that oc adm must-gather transferred from the pods to your client machine:

1 2: The packet captures are stored in directories that identify the hostname, container, and file name. If you did not specify the --node-selector argument, then the directory level for the hostname is not present.

5.5.2. Collecting a network trace from an OpenShift Dedicated node or container

When investigating potential network-related OpenShift Dedicated issues, Red Hat Support might request a network packet trace from a specific OpenShift Dedicated cluster node or from a specific container. The recommended method to capture a network trace in OpenShift Dedicated is through a debug pod.

Prerequisites

You have access to the cluster as a user with the cluster-admin role.
Note
In OpenShift Dedicated deployments, customers who are not using the Customer Cloud Subscription (CCS) model cannot use the oc debug command as it requires cluster-admin privileges.
You have installed the OpenShift CLI (oc).
You have an existing Red Hat Support case ID.

Procedure

Obtain a list of cluster nodes:
```
$ oc get nodes
```
Enter into a debug session on the target node. This step instantiates a debug pod called <node_name>-debug:
```
$ oc debug node/my-cluster-node
```
Set /host as the root directory within the debug shell. The debug pod mounts the host’s root file system in /host within the pod. By changing the root directory to /host, you can run binaries contained in the host’s executable paths:
```
# chroot /host
```
From within the chroot environment console, obtain the node’s interface names:
```
# ip ad
```
Start a toolbox container, which includes the required binaries and plugins to run sosreport:
```
# toolbox
```
Note
If an existing toolbox pod is already running, the toolbox command outputs 'toolbox-' already exists. Trying to start…. To avoid tcpdump issues, remove the running toolbox container with podman rm toolbox- and spawn a new toolbox container.
Initiate a tcpdump session on the cluster node and redirect output to a capture file. This example uses ens5 as the interface name:
```
$ tcpdump -nn -s 0 -i ens5 -w /host/var/tmp/my-cluster-node_$(date +%d_%m_%Y-%H_%M_%S-%Z).pcap  1
```
1
The tcpdump capture file’s path is outside of the chroot environment because the toolbox container mounts the host’s root directory at /host.
If a tcpdump capture is required for a specific container on the node, follow these steps.
1. Determine the target container ID. The chroot host command precedes the crictl command in this step because the toolbox container mounts the host’s root directory at /host:
```
# chroot /host crictl ps
```
2. Determine the container’s process ID. In this example, the container ID is a7fe32346b120:
```
# chroot /host crictl inspect --output yaml a7fe32346b120 | grep 'pid' | awk '{print $2}'
```
3. Initiate a tcpdump session on the container and redirect output to a capture file. This example uses 49628 as the container’s process ID and ens5 as the interface name. The nsenter command enters the namespace of a target process and runs a command in its namespace. because the target process in this example is a container’s process ID, the tcpdump command is run in the container’s namespace from the host:
```
# nsenter -n -t 49628 -- tcpdump -nn -i ens5 -w /host/var/tmp/my-cluster-node-my-container_$(date +%d_%m_%Y-%H_%M_%S-%Z).pcap  1
```
  1
  The tcpdump capture file’s path is outside of the chroot environment because the toolbox container mounts the host’s root directory at /host.
Provide the tcpdump capture file to Red Hat Support for analysis, using one of the following methods.
- Upload the file to an existing Red Hat support case directly from an OpenShift Dedicated cluster.
  1. From within the toolbox container, run redhat-support-tool to attach the file directly to an existing Red Hat Support case. This example uses support case ID 01234567:
    # redhat-support-tool addattachment -c 01234567 /host/var/tmp/my-tcpdump-capture-file.pcap 1
    1
    The toolbox container mounts the host’s root directory at /host. Reference the absolute path from the toolbox container’s root directory, including /host/, when specifying files to upload through the redhat-support-tool command.
- Upload the file to an existing Red Hat support case.
  1. Concatenate the sosreport archive by running the oc debug node/<node_name> command and redirect the output to a file. This command assumes you have exited the previous oc debug session:
    $ oc debug node/my-cluster-node -- bash -c 'cat /host/var/tmp/my-tcpdump-capture-file.pcap' > /tmp/my-tcpdump-capture-file.pcap 1
    1
    The debug container mounts the host’s root directory at /host. Reference the absolute path from the debug container’s root directory, including /host, when specifying target files for concatenation.
  2. Navigate to an existing support case within the Customer Support page of the Red Hat Customer Portal.
  3. Select Attach files and follow the prompts to upload the file.

5.5.3. Providing diagnostic data to Red Hat Support

When investigating OpenShift Dedicated issues, Red Hat Support might ask you to upload diagnostic data to a support case. Files can be uploaded to a support case through the Red Hat Customer Portal, or from an OpenShift Dedicated cluster directly by using the redhat-support-tool command.

Prerequisites

You have access to the cluster as a user with the cluster-admin role.
Note
In OpenShift Dedicated deployments, customers who are not using the Customer Cloud Subscription (CCS) model cannot use the oc debug command as it requires cluster-admin privileges.
You have installed the OpenShift CLI (oc).
You have an existing Red Hat Support case ID.

Procedure

Upload diagnostic data to an existing Red Hat support case through the Red Hat Customer Portal.
1. Concatenate a diagnostic file contained on an OpenShift Dedicated node by using the oc debug node/<node_name> command and redirect the output to a file. The following example copies /host/var/tmp/my-diagnostic-data.tar.gz from a debug container to /var/tmp/my-diagnostic-data.tar.gz:
```
$ oc debug node/my-cluster-node -- bash -c 'cat /host/var/tmp/my-diagnostic-data.tar.gz' > /var/tmp/my-diagnostic-data.tar.gz 1
```
  1
  The debug container mounts the host’s root directory at /host. Reference the absolute path from the debug container’s root directory, including /host, when specifying target files for concatenation.
2. Navigate to an existing support case within the Customer Support page of the Red Hat Customer Portal.
3. Select Attach files and follow the prompts to upload the file.

5.5.4. About `toolbox`

toolbox is a tool that starts a container on a Red Hat Enterprise Linux CoreOS (RHCOS) system. The tool is primarily used to start a container that includes the required binaries and plugins that are needed to run commands such as sosreport and redhat-support-tool.

The primary purpose for a toolbox container is to gather diagnostic information and to provide it to Red Hat Support. However, if additional diagnostic tools are required, you can add RPM packages or run an image that is an alternative to the standard support tools image.

Installing packages to a `toolbox` container

By default, running the toolbox command starts a container with the registry.redhat.io/rhel9/support-tools:latest image. This image contains the most frequently used support tools. If you need to collect node-specific data that requires a support tool that is not part of the image, you can install additional packages.

Prerequisites

You have accessed a node with the oc debug node/<node_name> command.
You can access your system as a user with root privileges.

Procedure

Set /host as the root directory within the debug shell. The debug pod mounts the host’s root file system in /host within the pod. By changing the root directory to /host, you can run binaries contained in the host’s executable paths:
```
# chroot /host
```
Start the toolbox container:
```
# toolbox
```
Install the additional package, such as wget:
```
# dnf install -y <package_name>
```

Starting an alternative image with `toolbox`

By default, running the toolbox command starts a container with the registry.redhat.io/rhel9/support-tools:latest image.

Note

You can start an alternative image by creating a .toolboxrc file and specifying the image to run. However, running an older version of the support-tools image, such as registry.redhat.io/rhel8/support-tools:latest, is not supported on OpenShift Dedicated 4.

Prerequisites

You have accessed a node with the oc debug node/<node_name> command.
You can access your system as a user with root privileges.

Procedure

Set /host as the root directory within the debug shell. The debug pod mounts the host’s root file system in /host within the pod. By changing the root directory to /host, you can run binaries contained in the host’s executable paths:
```
# chroot /host
```
Optional: If you need to use an alternative image instead of the default image, create a .toolboxrc file in the home directory for the root user ID, and specify the image metadata:
```
REGISTRY=quay.io             1
IMAGE=fedora/fedora:latest   2
TOOLBOX_NAME=toolbox-fedora-latest  3
```
1
Optional: Specify an alternative container registry.
2
Specify an alternative image to start.
3
Optional: Specify an alternative name for the toolbox container.
Start a toolbox container by entering the following command:
```
# toolbox
```
Note
If an existing toolbox pod is already running, the toolbox command outputs 'toolbox-' already exists. Trying to start…. To avoid issues with sosreport plugins, remove the running toolbox container with podman rm toolbox- and then spawn a new toolbox container.

Chapter 6. Summarizing cluster specifications

6.1. Summarizing cluster specifications by using a cluster version object

You can obtain a summary of OpenShift Dedicated cluster specifications by querying the clusterversion resource.

Prerequisites

You have access to the cluster as a user with the dedicated-admin role.
You have installed the OpenShift CLI (oc).

Procedure

Query cluster version, availability, uptime, and general status:

$ oc get clusterversion

Example output

Chapter 7. Troubleshooting

7.1. Verifying node health

7.1.1. Reviewing node status, resource usage, and configuration

Review cluster node health status, resource consumption statistics, and node logs. Additionally, query kubelet status on individual nodes.

Prerequisites

You have access to the cluster as a user with the dedicated-admin role.
You have installed the OpenShift CLI (oc).

Procedure

List the name, status, and role for all nodes in the cluster:
```
$ oc get nodes
```
Summarize CPU and memory usage for each node within the cluster:
```
$ oc adm top nodes
```
Summarize CPU and memory usage for a specific node:
```
$ oc adm top node my-node
```

7.2. Troubleshooting Operator issues

Operators are a method of packaging, deploying, and managing an OpenShift Dedicated application. They act like an extension of the software vendor’s engineering team, watching over an OpenShift Dedicated environment and using its current state to make decisions in real time. Operators are designed to handle upgrades seamlessly, react to failures automatically, and not take shortcuts, such as skipping a software backup process to save time.

OpenShift Dedicated 4 includes a default set of Operators that are required for proper functioning of the cluster. These default Operators are managed by the Cluster Version Operator (CVO).

As a cluster administrator, you can install application Operators from the OperatorHub using the OpenShift Dedicated web console or the CLI. You can then subscribe the Operator to one or more namespaces to make it available for developers on your cluster. Application Operators are managed by Operator Lifecycle Manager (OLM).

If you experience Operator issues, verify Operator subscription status. Check Operator pod health across the cluster and gather Operator logs for diagnosis.

7.2.1. Operator subscription condition types

Subscriptions can report the following condition types:

Table 7.1. Subscription condition types
Condition	Description
`CatalogSourcesUnhealthy`	Some or all of the catalog sources to be used in resolution are unhealthy.
`InstallPlanMissing`	An install plan for a subscription is missing.
`InstallPlanPending`	An install plan for a subscription is pending installation.
`InstallPlanFailed`	An install plan for a subscription has failed.
`ResolutionFailed`	The dependency resolution for a subscription has failed.

Note

Default OpenShift Dedicated cluster Operators are managed by the Cluster Version Operator (CVO) and they do not have a Subscription object. Application Operators are managed by Operator Lifecycle Manager (OLM) and they have a Subscription object.

7.2.2. Viewing Operator subscription status by using the CLI

You can view Operator subscription status by using the CLI.

Prerequisites

You have access to the cluster as a user with the dedicated-admin role.
You have installed the OpenShift CLI (oc).

Procedure

List Operator subscriptions:
```
$ oc get subs -n <operator_namespace>
```

Use the oc describe command to inspect a Subscription resource:

$ oc describe sub <subscription_name> -n <operator_namespace>

In the command output, find the Conditions section for the status of Operator subscription condition types. In the following example, the CatalogSourcesUnhealthy condition type has a status of false because all available catalog sources are healthy:

7.2.3. Viewing Operator catalog source status by using the CLI

You can view the status of an Operator catalog source by using the CLI.

Prerequisites

You have access to the cluster as a user with the dedicated-admin role.
You have installed the OpenShift CLI (oc).

Procedure

List the catalog sources in a namespace. For example, you can check the openshift-marketplace namespace, which is used for cluster-wide catalog sources:

$ oc get catalogsources -n openshift-marketplace

Example output

    Service Namespace:  openshift-marketplace
# ...

In the preceding example output, the last observed state is TRANSIENT_FAILURE. This state indicates that there is a problem establishing a connection for the catalog source.

List the pods in the namespace where your catalog source was created:

$ oc get pods -n openshift-marketplace

Example output

NAME                                    READY   STATUS             RESTARTS   AGE

7.2.4. Querying Operator pod status

You can list Operator pods within a cluster and their status. You can also collect a detailed Operator pod summary.

Prerequisites

You have access to the cluster as a user with the dedicated-admin role.
Your API service is still functional.
You have installed the OpenShift CLI (oc).

Procedure

List Operators running in the cluster. The output includes Operator version, availability, and up-time information:
```
$ oc get clusteroperators
```
List Operator pods running in the Operator’s namespace, plus pod status, restarts, and age:
```
$ oc get pod -n <operator_namespace>
```

Output a detailed Operator pod summary:

$ oc describe pod <operator_pod_name> -n <operator_namespace>

7.2.5. Gathering Operator logs

If you experience Operator issues, you can gather detailed diagnostic information from Operator pod logs.

Prerequisites

You have access to the cluster as a user with the dedicated-admin role.
Your API service is still functional.
You have installed the OpenShift CLI (oc).
You have the fully qualified domain names of the control plane or control plane machines.

Procedure

List the Operator pods that are running in the Operator’s namespace, plus the pod status, restarts, and age:
```
$ oc get pods -n <operator_namespace>
```
Review logs for an Operator pod:
```
$ oc logs pod/<pod_name> -n <operator_namespace>
```
If an Operator pod has multiple containers, the preceding command will produce an error that includes the name of each container. Query logs from an individual container:
```
$ oc logs pod/<operator_pod_name> -c <container_name> -n <operator_namespace>
```
If the API is not functional, review Operator pod and container logs on each control plane node by using SSH instead. Replace <master-node>.<cluster_name>.<base_domain> with appropriate values.
1. List pods on each control plane node:
```
$ ssh core@<master-node>.<cluster_name>.<base_domain> sudo crictl pods
```
2. For any Operator pods not showing a Ready status, inspect the pod’s status in detail. Replace <operator_pod_id> with the Operator pod’s ID listed in the output of the preceding command:
```
$ ssh core@<master-node>.<cluster_name>.<base_domain> sudo crictl inspectp <operator_pod_id>
```
3. List containers related to an Operator pod:
```
$ ssh core@<master-node>.<cluster_name>.<base_domain> sudo crictl ps --pod=<operator_pod_id>
```
4. For any Operator container not showing a Ready status, inspect the container’s status in detail. Replace <container_id> with a container ID listed in the output of the preceding command:
```
$ ssh core@<master-node>.<cluster_name>.<base_domain> sudo crictl inspect <container_id>
```
5. Review the logs for any Operator containers not showing a Ready status. Replace <container_id> with a container ID listed in the output of the preceding command:
```
$ ssh core@<master-node>.<cluster_name>.<base_domain> sudo crictl logs -f <container_id>
```
  Note
  OpenShift Dedicated 4 cluster nodes running Red Hat Enterprise Linux CoreOS (RHCOS) are immutable and rely on Operators to apply cluster changes. Accessing cluster nodes by using SSH is not recommended. Before attempting to collect diagnostic data over SSH, review whether the data collected by running oc adm must gather and other oc commands is sufficient instead. However, if the OpenShift Dedicated API is not available, or the kubelet is not properly functioning on the target node, oc operations will be impacted. In such situations, it is possible to access nodes using ssh core@<node>.<cluster_name>.<base_domain>.

7.3. Investigating pod issues

OpenShift Dedicated leverages the Kubernetes concept of a pod, which is one or more containers deployed together on one host. A pod is the smallest compute unit that can be defined, deployed, and managed on OpenShift Dedicated 4.

After a pod is defined, it is assigned to run on a node until its containers exit, or until it is removed. Depending on policy and exit code, Pods are either removed after exiting or retained so that their logs can be accessed.

The first thing to check when pod issues arise is the pod’s status. If an explicit pod failure has occurred, observe the pod’s error state to identify specific image, container, or pod network issues. Focus diagnostic data collection according to the error state. Review pod event messages, as well as pod and container log information. Diagnose issues dynamically by accessing running Pods on the command line, or start a debug pod with root access based on a problematic pod’s deployment configuration.

7.3.1. Understanding pod error states

Pod failures return explicit error states that can be observed in the status field in the output of oc get pods. Pod error states cover image, container, and container network related failures.

The following table provides a list of pod error states along with their descriptions.

Table 7.2. Pod error states
Pod error state	Description
`ErrImagePull`	Generic image retrieval error.
`ErrImagePullBackOff`	Image retrieval failed and is backed off.
`ErrInvalidImageName`	The specified image name was invalid.
`ErrImageInspect`	Image inspection did not succeed.
`ErrImageNeverPull`	`PullPolicy` is set to `NeverPullImage` and the target image is not present locally on the host.
`ErrRegistryUnavailable`	When attempting to retrieve an image from a registry, an HTTP error was encountered.
`ErrContainerNotFound`	The specified container is either not present or not managed by the kubelet, within the declared pod.
`ErrRunInitContainer`	Container initialization failed.
`ErrRunContainer`	None of the pod’s containers started successfully.
`ErrKillContainer`	None of the pod’s containers were killed successfully.
`ErrCrashLoopBackOff`	A container has terminated. The kubelet will not attempt to restart it.
`ErrVerifyNonRoot`	A container or image attempted to run with root privileges.
`ErrCreatePodSandbox`	Pod sandbox creation did not succeed.
`ErrConfigPodSandbox`	Pod sandbox configuration was not obtained.
`ErrKillPodSandbox`	A pod sandbox did not stop successfully.
`ErrSetupNetwork`	Network initialization failed.
`ErrTeardownNetwork`	Network termination failed.

7.3.2. Reviewing pod status

You can query pod status and error states. You can also query a pod’s associated deployment configuration and review base image availability.

Prerequisites

You have access to the cluster as a user with the dedicated-admin role.
You have installed the OpenShift CLI (oc).
skopeo is installed.

Procedure

Switch into a project:
```
$ oc project <project_name>
```
List pods running within the namespace, as well as pod status, error states, restarts, and age:
```
$ oc get pods
```
Determine whether the namespace is managed by a deployment configuration:
```
$ oc status
```
If the namespace is managed by a deployment configuration, the output includes the deployment configuration name and a base image reference.
Inspect the base image referenced in the preceding command’s output:
```
$ skopeo inspect docker://<image_reference>
```
If the base image reference is not correct, update the reference in the deployment configuration:
```
$ oc edit deployment/my-deployment
```
When deployment configuration changes on exit, the configuration will automatically redeploy. Watch pod status as the deployment progresses, to determine whether the issue has been resolved:
```
$ oc get pods -w
```
Review events within the namespace for diagnostic information relating to pod failures:
```
$ oc get events
```

7.3.3. Inspecting pod and container logs

You can inspect pod and container logs for warnings and error messages related to explicit pod failures. Depending on policy and exit code, pod and container logs remain available after pods have been terminated.

Prerequisites

You have access to the cluster as a user with the dedicated-admin role.
Your API service is still functional.
You have installed the OpenShift CLI (oc).

Procedure

Query logs for a specific pod:
```
$ oc logs <pod_name>
```
Query logs for a specific container within a pod:
```
$ oc logs <pod_name> -c <container_name>
```
Logs retrieved using the preceding oc logs commands are composed of messages sent to stdout within pods or containers.

Inspect logs contained in /var/log/ within a pod.

List log files and subdirectories contained in /var/log within a pod:

$ oc exec <pod_name>  -- ls -alh /var/log

Example output

```
Query a specific log file contained in /var/log within a specific container:
```
$ oc exec <pod_name> -c <container_name> cat /var/log/<path_to_log>
```

7.3.4. Accessing running pods

You can review running pods dynamically by opening a shell inside a pod or by gaining network access through port forwarding.

Prerequisites

You have access to the cluster as a user with the dedicated-admin role.
Your API service is still functional.
You have installed the OpenShift CLI (oc).

Procedure

Switch into the project that contains the pod you would like to access. This is necessary because the oc rsh command does not accept the -n namespace option:
```
$ oc project <namespace>
```
Start a remote shell into a pod:
```
$ oc rsh <pod_name>  1
```
1
If a pod has multiple containers, oc rsh defaults to the first container unless -c <container_name> is specified.
Start a remote shell into a specific container within a pod:
```
$ oc rsh -c <container_name> pod/<pod_name>
```
Create a port forwarding session to a port on a pod:
```
$ oc port-forward <pod_name> <host_port>:<pod_port>  1
```
1
Enter Ctrl+C to cancel the port forwarding session.

7.3.5. Starting debug pods with root access

You can start a debug pod with root access, based on a problematic pod’s deployment or deployment configuration. Pod users typically run with non-root privileges, but running troubleshooting pods with temporary root privileges can be useful during issue investigation.

Prerequisites

You have access to the cluster as a user with the dedicated-admin role.
Your API service is still functional.
You have installed the OpenShift CLI (oc).

Procedure

Start a debug pod with root access, based on a deployment.
1. Obtain a project’s deployment name:
```
$ oc get deployment -n <project_name>
```
2. Start a debug pod with root privileges, based on the deployment:
```
$ oc debug deployment/my-deployment --as-root -n <project_name>
```
Start a debug pod with root access, based on a deployment configuration.
1. Obtain a project’s deployment configuration name:
```
$ oc get deploymentconfigs -n <project_name>
```
2. Start a debug pod with root privileges, based on the deployment configuration:
```
$ oc debug deploymentconfig/my-deployment-configuration --as-root -n <project_name>
```

Note

You can append -- <command> to the preceding oc debug commands to run individual commands within a debug pod, instead of running an interactive shell.

7.3.6. Copying files to and from pods and containers

You can copy files to and from a pod to test configuration changes or gather diagnostic information.

Prerequisites

You have access to the cluster as a user with the dedicated-admin role.
Your API service is still functional.
You have installed the OpenShift CLI (oc).

Procedure

Copy a file to a pod:
```
$ oc cp <local_path> <pod_name>:/<path> -c <container_name>  1
```
1
The first container in a pod is selected if the -c option is not specified.
Copy a file from a pod:
```
$ oc cp <pod_name>:/<path>  -c <container_name> <local_path>  1
```
1
The first container in a pod is selected if the -c option is not specified.
Note
For oc cp to function, the tar binary must be available within the container.

7.4. Troubleshooting storage issues

7.4.1. Resolving multi-attach errors

When a node crashes or shuts down abruptly, the attached ReadWriteOnce (RWO) volume is expected to be unmounted from the node so that it can be used by a pod scheduled on another node.

However, mounting on a new node is not possible because the failed node is unable to unmount the attached volume.

A multi-attach error is reported:

Example output

Unable to attach or mount volumes: unmounted volumes=[sso-mysql-pvol], unattached volumes=[sso-mysql-pvol default-token-x4rzc]: timed out waiting for the condition
Multi-Attach error for volume "pvc-8837384d-69d7-40b2-b2e6-5df86943eef9" Volume is already used by pod(s) sso-mysql-1-ns6b4

Procedure

To resolve the multi-attach issue, use one of the following solutions:

Enable multiple attachments by using RWX volumes.
For most storage solutions, you can use ReadWriteMany (RWX) volumes to prevent multi-attach errors.
Recover or delete the failed node when using an RWO volume.
For storage that does not support RWX, such as VMware vSphere, RWO volumes must be used instead. However, RWO volumes cannot be mounted on multiple nodes.
If you encounter a multi-attach error message with an RWO volume, force delete the pod on a shutdown or crashed node to avoid data loss in critical workloads, such as when dynamic persistent volumes are attached.
```
$ oc delete pod <old_pod> --force=true --grace-period=0
```
This command deletes the volumes stuck on shutdown or crashed nodes after six minutes.

7.5. Investigating monitoring issues

OpenShift Dedicated includes a preconfigured, preinstalled, and self-updating monitoring stack that provides monitoring for core platform components. In OpenShift Dedicated 4, cluster administrators can optionally enable monitoring for user-defined projects.

Use these procedures if the following issues occur:

Your own metrics are unavailable.
Prometheus is consuming a lot of disk space.
The KubePersistentVolumeFillingUp alert is firing for Prometheus.

7.5.1. Investigating why user-defined project metrics are unavailable

ServiceMonitor resources enable you to determine how to use the metrics exposed by a service in user-defined projects. Follow the steps outlined in this procedure if you have created a ServiceMonitor resource but cannot see any corresponding metrics in the Metrics UI.

Prerequisites

You have access to the cluster as a user with the dedicated-admin role.
You have installed the OpenShift CLI (oc).
You have enabled and configured monitoring for user-defined projects.
You have created a ServiceMonitor resource.

Procedure

Check that the corresponding labels match in the service and ServiceMonitor resource configurations.
1. Obtain the label defined in the service. The following example queries the prometheus-example-app service in the ns1 project:
```
$ oc -n ns1 get service prometheus-example-app -o yaml
```
  Example output
```
  labels:
    app: prometheus-example-app
```
2. Check that the matchLabels definition in the ServiceMonitor resource configuration matches the label output in the preceding step. The following example queries the prometheus-example-monitor service monitor in the ns1 project:
```
$ oc -n ns1 get servicemonitor prometheus-example-monitor -o yaml
```
  Example output
```
apiVersion: v1
kind: ServiceMonitor
metadata:
  name: prometheus-example-monitor
  namespace: ns1
spec:
  endpoints:
  - interval: 30s
    port: web
    scheme: http
  selector:
    matchLabels:
      app: prometheus-example-app
```
  Note
  You can check service and ServiceMonitor resource labels as a developer with view permissions for the project.

Inspect the logs for the Prometheus Operator in the openshift-user-workload-monitoring project.

List the pods in the openshift-user-workload-monitoring project:

$ oc -n openshift-user-workload-monitoring get pods

Example output

NAME                                   READY   STATUS    RESTARTS   AGE
prometheus-operator-776fcbbd56-2nbfm   2/2     Running   0          132m
prometheus-user-workload-0             5/5     Running   1          132m
prometheus-user-workload-1             5/5     Running   1          132m
thanos-ruler-user-workload-0           3/3     Running   0          132m
thanos-ruler-user-workload-1           3/3     Running   0          132m

Obtain the logs from the prometheus-operator container in the prometheus-operator pod. In the following example, the pod is called prometheus-operator-776fcbbd56-2nbfm:

$ oc -n openshift-user-workload-monitoring logs prometheus-operator-776fcbbd56-2nbfm -c prometheus-operator

If there is a issue with the service monitor, the logs might include an error similar to this example:

level=warn ts=2020-08-10T11:48:20.906739623Z caller=operator.go:1829 component=prometheusoperator msg="skipping servicemonitor" error="it accesses file system via bearer token file which Prometheus specification prohibits" servicemonitor=eagle/eagle namespace=openshift-user-workload-monitoring prometheus=user-workload

Review the target status for your endpoint on the Metrics targets page in the OpenShift Dedicated web console UI.
1. Log in to the OpenShift Dedicated web console and navigate to Observe → Targets in the Administrator perspective.
2. Locate the metrics endpoint in the list, and review the status of the target in the Status column.
3. If the Status is Down, click the URL for the endpoint to view more information on the Target Details page for that metrics target.
Configure debug level logging for the Prometheus Operator in the openshift-user-workload-monitoring project.
1. Edit the user-workload-monitoring-config ConfigMap object in the openshift-user-workload-monitoring project:
```
$ oc -n openshift-user-workload-monitoring edit configmap user-workload-monitoring-config
```
2. Add logLevel: debug for prometheusOperator under data/config.yaml to set the log level to debug:
```
apiVersion: v1
kind: ConfigMap
metadata:
  name: user-workload-monitoring-config
  namespace: openshift-user-workload-monitoring
data:
  config.yaml: |
    prometheusOperator:
      logLevel: debug
# ...
```
3. Save the file to apply the changes. The affected prometheus-operator pod is automatically redeployed.
4. Confirm that the debug log-level has been applied to the prometheus-operator deployment in the openshift-user-workload-monitoring project:
```
$ oc -n openshift-user-workload-monitoring get deploy prometheus-operator -o yaml |  grep "log-level"
```
  Example output
```
        - --log-level=debug
```
  Debug level logging will show all calls made by the Prometheus Operator.
5. Check that the prometheus-operator pod is running:
```
$ oc -n openshift-user-workload-monitoring get pods
```
  Note
  If an unrecognized Prometheus Operator loglevel value is included in the config map, the prometheus-operator pod might not restart successfully.
6. Review the debug logs to see if the Prometheus Operator is using the ServiceMonitor resource. Review the logs for other related errors.

7.5.2. Determining why Prometheus is consuming a lot of disk space

Developers can create labels to define attributes for metrics in the form of key-value pairs. The number of potential key-value pairs corresponds to the number of possible values for an attribute. An attribute that has an unlimited number of potential values is called an unbound attribute. For example, a customer_id attribute is unbound because it has an infinite number of possible values.

Every assigned key-value pair has a unique time series. The use of many unbound attributes in labels can result in an exponential increase in the number of time series created. This can impact Prometheus performance and can consume a lot of disk space.

You can use the following measures when Prometheus consumes a lot of disk:

Check the time series database (TSDB) status using the Prometheus HTTP API for more information about which labels are creating the most time series data. Doing so requires cluster administrator privileges.
Check the number of scrape samples that are being collected.
Reduce the number of unique time series that are created by reducing the number of unbound attributes that are assigned to user-defined metrics.
Note
Using attributes that are bound to a limited set of possible values reduces the number of potential key-value pair combinations.
Enforce limits on the number of samples that can be scraped across user-defined projects. This requires cluster administrator privileges.

Prerequisites

You have access to the cluster as a user with the dedicated-admin role.
You have installed the OpenShift CLI (oc).

Procedure

In the Administrator perspective, navigate to Observe → Metrics.
Enter a Prometheus Query Language (PromQL) query in the Expression field. The following example queries help to identify high cardinality metrics that might result in high disk space consumption:
- By running the following query, you can identify the ten jobs that have the highest number of scrape samples:
```
topk(10, max by(namespace, job) (topk by(namespace, job) (1, scrape_samples_post_metric_relabeling)))
```
- By running the following query, you can pinpoint time series churn by identifying the ten jobs that have created the most time series data in the last hour:
```
topk(10, sum by(namespace, job) (sum_over_time(scrape_series_added[1h])))
```
Investigate the number of unbound label values assigned to metrics with higher than expected scrape sample counts:
- If the metrics relate to a user-defined project, review the metrics key-value pairs assigned to your workload. These are implemented through Prometheus client libraries at the application level. Try to limit the number of unbound attributes referenced in your labels.
- If the metrics relate to a core OpenShift Dedicated project, create a Red Hat support case on the Red Hat Customer Portal.

Review the TSDB status using the Prometheus HTTP API by following these steps when logged in as a dedicated-admin:

Get the Prometheus API route URL by running the following command:

$ HOST=$(oc -n openshift-monitoring get route prometheus-k8s -ojsonpath={.status.ingress[].host})

Extract an authentication token by running the following command:
```
$ TOKEN=$(oc whoami -t)
```

Query the TSDB status for Prometheus by running the following command:

$ curl -H "Authorization: Bearer $TOKEN" -k "https://$HOST/api/v1/status/tsdb"

Example output

7.5.3. Resolving the KubePersistentVolumeFillingUp alert firing for Prometheus

As a cluster administrator, you can resolve the KubePersistentVolumeFillingUp alert being triggered for Prometheus.

The critical alert fires when a persistent volume (PV) claimed by a prometheus-k8s-* pod in the openshift-monitoring project has less than 3% total space remaining. This can cause Prometheus to function abnormally.

Note

There are two KubePersistentVolumeFillingUp alerts:

Critical alert: The alert with the severity="critical" label is triggered when the mounted PV has less than 3% total space remaining.
Warning alert: The alert with the severity="warning" label is triggered when the mounted PV has less than 15% total space remaining and is expected to fill up within four days.

To address this issue, you can remove Prometheus time-series database (TSDB) blocks to create more space for the PV.

Prerequisites

You have access to the cluster as a user with the dedicated-admin role.
You have installed the OpenShift CLI (oc).

Procedure

List the size of all TSDB blocks, sorted from oldest to newest, by running the following command:

$ oc debug <prometheus_k8s_pod_name> -n openshift-monitoring \1
-c prometheus --image=$(oc get po -n openshift-monitoring <prometheus_k8s_pod_name> \2
-o jsonpath='{.spec.containers[?(@.name=="prometheus")].image}') \
-- sh -c 'cd /prometheus/;du -hs $(ls -dt */ | grep -Eo "[0-9|A-Z]{26}")'

1 2: Replace <prometheus_k8s_pod_name> with the pod mentioned in the KubePersistentVolumeFillingUp alert description.

Example output

308M    01HVKMPKQWZYWS8WVDAYQHNMW6
52M     01HVK64DTDA81799TBR9QDECEZ
102M    01HVK64DS7TRZRWF2756KHST5X
140M    01HVJS59K11FBVAPVY57K88Z11
90M     01HVH2A5Z58SKT810EM6B9AT50
152M    01HV8ZDVQMX41MKCN84S32RRZ1
354M    01HV6Q2N26BK63G4RYTST71FBF
156M    01HV664H9J9Z1FTZD73RD1563E
216M    01HTHXB60A7F239HN7S2TENPNS
104M    01HTHMGRXGS0WXA3WATRXHR36B

Identify which and how many blocks could be removed, then remove the blocks. The following example command removes the three oldest Prometheus TSDB blocks from the prometheus-k8s-0 pod:

$ oc debug prometheus-k8s-0 -n openshift-monitoring \
-c prometheus --image=$(oc get po -n openshift-monitoring prometheus-k8s-0 \
-o jsonpath='{.spec.containers[?(@.name=="prometheus")].image}') \
-- sh -c 'ls -latr /prometheus/ | egrep -o "[0-9|A-Z]{26}" | head -3 | \
while read BLOCK; do rm -r /prometheus/$BLOCK; done'

Verify the usage of the mounted PV and ensure there is enough space available by running the following command:

$ oc debug <prometheus_k8s_pod_name> -n openshift-monitoring \1
--image=$(oc get po -n openshift-monitoring <prometheus_k8s_pod_name> \2
-o jsonpath='{.spec.containers[?(@.name=="prometheus")].image}') -- df -h /prometheus/

1 2: Replace <prometheus_k8s_pod_name> with the pod mentioned in the KubePersistentVolumeFillingUp alert description.

The following example output shows the mounted PV claimed by the prometheus-k8s-0 pod that has 63% of space remaining:

Example output

Starting pod/prometheus-k8s-0-debug-j82w4 ...
Filesystem      Size  Used Avail Use% Mounted on
/dev/nvme0n1p4  40G   15G  40G  37% /prometheus

7.6. Diagnosing OpenShift CLI (`oc`) issues

7.6.1. Understanding OpenShift CLI (`oc`) log levels

With the OpenShift CLI (oc), you can create applications and manage OpenShift Dedicated projects from a terminal.

If oc command-specific issues arise, increase the oc log level to output API request, API response, and curl request details generated by the command. This provides a granular view of a particular oc command’s underlying operation, which in turn might provide insight into the nature of a failure.

oc log levels range from 1 to 10. The following table provides a list of oc log levels, along with their descriptions.

Table 7.3. OpenShift CLI (oc) log levels
Log level	Description
1 to 5	No additional logging to stderr.
6	Log API requests to stderr.
7	Log API requests and headers to stderr.
8	Log API requests, headers, and body, plus API response headers and body to stderr.
9	Log API requests, headers, and body, API response headers and body, plus `curl` requests to stderr.
10	Log API requests, headers, and body, API response headers and body, plus `curl` requests to stderr, in verbose detail.

7.6.2. Specifying OpenShift CLI (`oc`) log levels

You can investigate OpenShift CLI (oc) issues by increasing the command’s log level.

The OpenShift Dedicated user’s current session token is typically included in logged curl requests where required. You can also obtain the current user’s session token manually, for use when testing aspects of an oc command’s underlying process step-by-step.

Prerequisites

Install the OpenShift CLI (oc).

Procedure

Specify the oc log level when running an oc command:
```
$ oc <command> --loglevel <log_level>
```
where:
<command>
Specifies the command you are running.
<log_level>
Specifies the log level to apply to the command.
To obtain the current user’s session token, run the following command:
```
$ oc whoami -t
```
Example output
```
sha256~RCV3Qcn7H-OEfqCGVI0CvnZ6...
```

7.7. Red Hat managed resources

7.7.1. Overview

The following covers all OpenShift Dedicated resources that are managed or protected by the Service Reliability Engineering Platform (SRE-P) Team. Customers should not attempt to modify these resources because doing so can lead to cluster instability.

7.7.2. Hive managed resources

The following list displays the OpenShift Dedicated resources managed by OpenShift Hive, the centralized fleet configuration management system. These resources are in addition to the OpenShift Container Platform resources created during installation. OpenShift Hive continually attempts to maintain consistency across all OpenShift Dedicated clusters. Changes to OpenShift Dedicated resources should be made through OpenShift Cluster Manager so that OpenShift Cluster Manager and Hive are synchronized. Contact ocm-feedback@redhat.com if OpenShift Cluster Manager does not support modifying the resources in question.

7.7.4. OpenShift Dedicated add-on namespaces

OpenShift Dedicated add-ons are services available for installation after cluster installation. These additional services include Red Hat OpenShift Dev Spaces, Red Hat OpenShift API Management, and Cluster Logging Operator. Any changes to resources within the following namespaces can be overridden by the add-on during upgrades, which can lead to unsupported configurations for the add-on functionality.

Example 7.3. List of add-on managed namespaces

7.7.5. OpenShift Dedicated validating webhooks

OpenShift Dedicated validating webhooks are a set of dynamic admission controls maintained by the OpenShift SRE team. These HTTP callbacks, also known as webhooks, are called for various types of requests to ensure cluster stability. The following list describes the various webhooks with rules containing the registered operations and resources that are controlled. Any attempt to circumvent these validating webhooks could affect the stability and supportability of the cluster.
