Gathering diagnostic information for support

When you open a support case, you must provide debugging information about your cluster to the Red Hat Support team. You can use the must-gather tool to collect diagnostic information for project-level resources, cluster-level resources, and Red Hat OpenShift GitOps components. 

For prompt support, provide diagnostic information for both OpenShift Container Platform and Red Hat OpenShift GitOps.

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.

    Example command
    $ oc adm must-gather --image=registry.redhat.io/openshift-gitops-1/must-gather-rhel8:v1.10.0

  • To collect the audit logs, use the -- /usr/bin/gather_audit_logs argument, as described in a following section.

    Example command
    $ oc adm must-gather -- /usr/bin/gather_audit_logs

    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. This directory is created in the current working directory.

Example pod
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.

Example command
$ oc adm must-gather --image=registry.redhat.io/openshift-gitops-1/must-gather-rhel8:v1.10.0

Collecting debugging data for Red Hat OpenShift GitOps

Use the oc adm must-gather CLI command to collect the following details about the cluster that is associated with Red Hat OpenShift GitOps:

  • The subscription and namespace of the Red Hat OpenShift GitOps Operator.

  • The namespaces where ArgoCD objects are available and the objects in those namespaces, such as ArgoCD, Applications, ApplicationSets, AppProjects, and configmaps.

  • A list of the namespaces that are managed by the Red Hat OpenShift GitOps Operator, and resources from those namespaces.

  • All GitOps-related custom resource objects and definitions.

  • Operator and Argo CD logs.

  • Warning and error-level events.

Prerequisites

  • You have logged in to the OpenShift Container Platform cluster as an administrator.

  • You have installed the OpenShift Container Platform CLI (oc).

  • You have installed the Red Hat OpenShift GitOps Operator.

Procedure

  1. Navigate to the directory where you want to store the debugging information.

  2. Run the oc adm must-gather command with the Red Hat OpenShift GitOps must-gather image:

    $ oc adm must-gather --image=registry.redhat.io/openshift-gitops-1/must-gather-rhel8:<image_version_tag> (1)
    1 The must-gather image for GitOps.
    Example command
    $ oc adm must-gather --image=registry.redhat.io/openshift-gitops-1/must-gather-rhel8:v1.10.0

    The must-gather tool creates a new directory that starts with ./must-gather.local in the current directory. For example, ./must-gather.local.4157245944708210399.

  3. Create a compressed file from the directory that was just created. For example, on a computer that uses a Linux operating system, run the following command:

    $ tar -cvaf must-gather.tar.gz must-gather.local.4157245944708210399 (1)
    1 Replace must-gather-local.4157245944708210399 with the actual directory name.

  4. Attach the compressed file to your support case on the Red Hat Customer Portal.
