   4 Ceph Manager Daemon
   5 ===================
   6
   7 The :term:`Ceph Manager` daemon (ceph-mgr) runs alongside monitor daemons,
   8 to provide additional monitoring and interfaces to external monitoring
   9 and management systems.
  10
  11 Since the 12.x (*luminous*) Ceph release, the ceph-mgr daemon is required for
  12 normal operations.  The ceph-mgr daemon is an optional component in
  13 the 11.x (*kraken*) Ceph release.
  14
  15 By default, the manager daemon requires no additional configuration, beyond
  16 ensuring it is running.  If there is no mgr daemon running, you will
  17 see a health warning to that effect, and some of the other information
  18 in the output of `ceph status` will be missing or stale until a mgr is started.
  19
  20 Use your normal deployment tools, such as ceph-ansible or ceph-deploy, to
  21 set up ceph-mgr daemons on each of your mon nodes.  It is not mandatory
  22 to place mgr daemons on the same nodes as mons, but it is almost always
  23 sensible.
