2 months ago Are there any chances for fixing it? datadog-agent-7.54.1-1.x86_64 + Ceph Pacific doesn't produce any mon-related metrics, that's the most crucial component to monitor in the cluster.
Some basic numbers (ceph.num_mons) could be extracted from ceph status, the more detailed metrics are on ceph tell mon.2 mon_status -fjson. The command proposed by @nik-johnson-net doesn't work for me.

"mon_status" has been moved to a daemon specific command, so instead the command must be issued like:
/usr/bin/ceph --cluster ceph daemon mon.node-a mon_status -fjsonA patch would need to locate the specific daemon to query.
