-Please note that the dashboard will *only* start on the manager which
-is active at that moment. Query the Ceph cluster status to see which
-manager is active (e.g., ``ceph mgr dump``).  In order to make the
-dashboard available via a consistent URL regardless of which manager
-daemon is currently active, you may want to set up a load balancer
-front-end to direct traffic to whichever manager endpoint is
-available. If you use a reverse http proxy that forwards a subpath to
-the dashboard, you need to configure ``url_prefix`` (see above).
