Description Luis Sanchez 2019-05-06 17:43:51 UTC 
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".

See https://kubernetes.io/docs/tasks/debug-application-cluster/determine-reason-pod-failure/#customizing-the-termination-message

Expected Results:
The termination message should appear in a pod container's  .status.lastState.terminated.message field.
