Chapter 5. Troubleshooting the Distributed Tracing Platform
You can diagnose and fix issues in TempoStack or TempoMonolithic instances by using various troubleshooting methods.
5.1. Collecting diagnostic data from the command line
When submitting a support case, it is helpful to include diagnostic information about your cluster to Red Hat Support. You can use the oc adm must-gather tool to gather diagnostic data for resources of various types, such as TempoStack or TempoMonolithic, and the created resources like Deployment, Pod, or ConfigMap. The oc adm must-gather tool creates a new pod that collects this data.
Procedure
From the directory where you want to save the collected data, run the
oc adm must-gathercommand to collect the data:Copy to Clipboard Copied! Toggle word wrap Toggle overflow oc adm must-gather --image=ghcr.io/grafana/tempo-operator/must-gather -- \ /usr/bin/must-gather --operator-namespace <operator_namespace>
$ oc adm must-gather --image=ghcr.io/grafana/tempo-operator/must-gather -- \ /usr/bin/must-gather --operator-namespace <operator_namespace>1 - 1
- The default namespace where the Operator is installed is
openshift-tempo-operator.
Verification
- Verify that the new directory is created and contains the collected data.
