The cluster-monitoring-operator pod does not provide a termination message, hindering debugging efforts when the pods are crash looping.
At minimum, the pod's terminationMessagePolicy should be "FallbackToLogsOnError".
The termination message should appear in a pod container's .status.lastState.terminated.message field.
A Pull Request with the fix has been made and it is about to be merged.
# oc -n openshift-monitoring get deploy cluster-monitoring-operator -oyaml | grep terminationMessagePolicy
