Thanks for your reply, Marc!
I did try to play with various debug settings. The issue is that mons
produce logs of all commands issued by clients, not just mgr. For example,
an Openstack Cinder node asking for space it can use:
Oct 9 07:59:01 ceph03 bash[4019]: debug 2023-10-09T07:59:01.303+0000
7f489da8f700 0 log_channel(audit) log [DBG] : from='client.?
10.208.1.11:0/3286277243' entity='client.cinder' cmd=[{"prefix":"osd pool
get-quota", "pool": "volumes-ssd", "format":"json"}]: dispatch
It is unclear which particular mon debug option out of many controls this
particular type of debug. I tried searching for documentation of mon debug
options to no avail.
