Getting support

If you experience difficulty with a procedure described in this documentation, or with OpenShift Container Platform in general, visit the Red Hat Customer Portal. From the Customer Portal, you can:

  • Search or browse through the Red Hat Knowledgebase of articles and solutions relating to Red Hat products.

  • Submit a support case to Red Hat Support.

  • Access other product documentation.

To identify issues with your cluster, you can use Insights in Red Hat OpenShift Cluster Manager. Insights provides details about issues and, if available, information on how to solve a problem.

If you have a suggestion for improving this documentation or have found an error, submit a Bugzilla report against the OpenShift Container Platform product for the Documentation component. Please provide specific details, such as the section name and OpenShift Container Platform version.

The must-gather tool enables you to collect diagnostic information about your OpenShift Container Platform cluster, including virtual machines and other data related to Red Hat OpenShift Service Mesh. You can send that diagnostic information to support for both OpenShift Container Platform and Red Hat OpenShift Service Mesh.

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, such as:

  • Resource definitions

  • Audit logs

  • Service logs

You can specify one or more images when you run the command by including the --image argument. When you specify an image, the tool collects data related to that feature or product.

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

Prerequisites

  • Access to the cluster as a user with the cluster-admin role. If you use Red Hat OpenShift Dedicated, you must have an account with the dedicated-admin role.

  • The OpenShift Container Platform CLI (oc) installed.

About collecting service mesh data

You can use the oc adm must-gather CLI command to collect information about your cluster, including features and objects associated with Red Hat OpenShift Service Mesh.

To collect Red Hat OpenShift Service Mesh data with must-gather, you must specify the Red Hat OpenShift Service Mesh image.

$ oc adm must-gather --image=registry.redhat.io/openshift-service-mesh/istio-must-gather-rhel8

To collect Red Hat OpenShift Service Mesh data for a specific control plane namespace with must-gather, you must specify the Red Hat OpenShift Service Mesh image and namespace. In this example, replace <namespace> with your control plane namespace, such as istio-system.

$ oc adm must-gather --image=registry.redhat.io/openshift-service-mesh/istio-must-gather-rhel8 gather <namespace>
