  Error: the service account for Hawkular Metrics does not have permission to view resources in this namespace. View permissions are required for Hawkular Metrics to function properly.
  Usually this can be resolved by running: oc adm policy add-role-to-user view system:serviceaccount:openshift-infra:hawkular -n openshift-infra
