Procedure
From the directory where you want to save the collected data, run the
oc adm must-gather
command to collect the data: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>
