Subject: mon/MgrMonitor: include standby manager details in ceph mgr stat
X-Git-Url: http://git-server-git.apps.pok.os.sepia.ceph.com/?a=commitdiff_plain;h=91c8003f475652357036c85a6040461aeff0539f;p=ceph.git

mon/MgrMonitor: include standby manager details in ceph mgr stat

Extend `ceph mgr stat` to include basic information about standby
manager daemons in a new `standbys` field. This improves visibility
into standby managers without requiring `ceph mgr dump`.

Fixes: https://tracker.ceph.com/issues/75464
