Description of problem: the alerts generated be components in openshift-storage namespace are shown as user defined ones instead of platform ones. I am not sure if I need to report this bug to monitoring team. The workaround is to set this label in the namespace: oc label namespace openshift-storage openshift.io/cluster-monitoring=true
