| 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. | |

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. | |
