-- **Monitors**: A :term:`Ceph Monitor` (``ceph-mon``) maintains maps
- of the cluster state, including the monitor map, manager map, the
- OSD map, the MDS map, and the CRUSH map. These maps are critical
- cluster state required for Ceph daemons to coordinate with each other.
- Monitors are also responsible for managing authentication between
- daemons and clients. At least three monitors are normally required
- for redundancy and high availability.
