I just noticed on my small Octopus cluster that the ceph-mgr on a mgr/mon node uses 3.6GB
of resident memory (RES) as you can see below from the top output:
PID USER PR NI VIRT RES SHR S %CPU %MEM TIME+ COMMAND
2704 167 20 0 5030528 3.6g 35796 S 6.6 47.2 23:08.18 ceph-mgr
2699 167 20 0 1291504 884796 23672 S 4.6 11.1 13:23.63 ceph-mon
Is there a way to limit the memory usage of ceph-mgr just like one can do with ceph OSD
I tried something like mgr_memory_target but that parameter does not exist.
