Chapter 2. Gathering data about your cluster

When opening a support case, it is often helpful to provide debugging information about your cluster to Red Hat Support.

It is recommended to provide:

2.1. About the must-gather tool
Copier lien

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.

2.2. 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

  • Access to the cluster as a user with the cluster-admin role.
  • The OpenShift Container Platform CLI (oc) installed.

Procedure

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

  2. Run the oc adm must-gather command: 

    $ oc adm must-gather
    Copy to Clipboard Toggle word wrap

  3. 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
    Copy to Clipboard Toggle word wrap
    1
    Make sure to replace must-gather-local.5421342344627712289/ with the actual directory name.
  4. Attach the compressed file to your support case on the Red Hat Customer Portal.

2.3. Obtaining your cluster ID

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

Prerequisites

  • Access to the cluster as a user with the cluster-admin role.
  • The OpenShift Container Platform CLI (oc) installed.

Procedure

  • To obtain your cluster ID using the OpenShift CLI (oc), run the following command: 

    $ oc get clusterversion -o jsonpath='{.items[].spec.clusterID}{"\n"}'
    Copy to Clipboard Toggle word wrap

  • To obtain your cluster ID using the OpenShift Container Platform web console:

    1. Navigate to Home Dashboards Overview.
    2. The value is available in the Cluster ID field of the Details section.
