When opening a support case, it is helpful to provide debugging information about your cluster to Red Hat Support.
The must-gather tool enables you to collect diagnostic information about your
OpenShift Container Platform cluster, including data related to
OpenShift Serverless.
For prompt support, supply diagnostic information for both OpenShift Container Platform and OpenShift Serverless.
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 plug-in 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-rhel8:v4.10.0To 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|
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.
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
...You can use the oc adm must-gather CLI command to collect information about your cluster, including features and objects associated with OpenShift Serverless. To collect OpenShift Serverless data with must-gather, you must specify the OpenShift Serverless image and the image tag for your installed version of OpenShift Serverless.
Install the OpenShift CLI (oc).
Collect data by using the oc adm must-gather command:
$ oc adm must-gather --image=registry.redhat.io/openshift-serverless-1/svls-must-gather-rhel8:<image_version_tag>$ oc adm must-gather --image=registry.redhat.io/openshift-serverless-1/svls-must-gather-rhel8:1.14.0
