The mgr daemon may be failed over by ceph if the active mgr is not responding and the standby mgr is available. If the active mgr changes the services for the dashboard and metrics will be updated with a label selector for the new active mgr. The services cannot direct traffic to the standby mgr or else they will be incorrectly redirected to the active mgr. Signed-off-by: Travis Nielsen <tnielsen@redhat.com>
