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