For prompt support, supply diagnostic information for both OpenShift Container Platform and OpenShift Serverless.
9.2.1. About the must-gather tool
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 plug-in image and writes into
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
--imageargument with an image, as listed in a following section.
$ oc adm must-gather --image=registry.redhat.io/container-native-virtualization/cnv-must-gather-rhel8:v4.9.0
To collect the audit logs, use the
-- /usr/bin/gather_audit_logsargument, as described in a following section.
$ oc adm must-gather -- /usr/bin/gather_audit_logsNote
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.
