I tried to get the counters, then I was pointed to enabling the module:
# ceph osd perf
osd commit_latency(ms) apply_latency(ms)
11 0 0
8 0 0
6 0 0
1 0 0
0 0 0
2 0 0
3 0 0
4 0 0
5 0 0
# ceph osd perf counters get 0
Error ENOTSUP: Module 'osd_perf_query' is not enabled/loaded (required
by command 'osd perf counters get'): use `ceph mgr module enable
osd_perf_query` to enable it
After enabling it, I get values:
# ceph osd perf
osd commit_latency(ms) apply_latency(ms)
11 184 184
8 8 8
6 17 17

4 33 33
5 166 166
# ceph osd perf query add all_subkeys
added query all_subkeys with id 0
# ceph osd perf counters get 0

Zitat von Janne Johansson <icepic.dz@xxxxxxxxx>:
I see the same on a newly deployed 17.2.8 cluster.
all empty perf values.

My ceph osd perf are all 0, do I need to enable module for this?
osd_perf_query? Where should I find this in manuals? Or do I just
need to wait?
[@ target]# ceph osd perf
osd commit_latency(ms) apply_latency(ms)
