For me, the perf stats are non-zero only for those OSD's that are currently writing. The others that are idle/reading show zero.

The two new ones have stats, all the others show zero.) -- linas On Fri, Nov 29, 2024 at 3:10 AM Eugen Block <eblock@xxxxxx> wrote: > > 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 > 1 4 4 > 0 3 3 > 2 72 72 > 3 9 9 > 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 > +----------------+------------------------------+---------+-----------+--------+-------+------------------------------+---------+-----------+----------+ > | CLIENT_ID | CLIENT_ADDRESS |POOL_ID |NAMESPACE > |OSD_ID |PG_ID | OBJECT_NAME |SNAP_ID |WRITE_OPS > |READ_OPS | > +----------------+------------------------------+---------+-----------+--------+-------+------------------------------+---------+-----------+----------+ > |client.2624154 | IP:0/47925986 | 18 | | 11 | > 18.0 |data_loggenerations_metadata | head | 0 | 6 | > |client.2624154 | IP:0/47925986 | 19 | | 2 | > 19.1 | notify.0 | head | 0 | 6 | > ... > > Zitat von Janne Johansson <icepic.dz@xxxxxxxxx>: > > > I see the same on a newly deployed 17.2.8 cluster. > > all empty perf values. > > > > Den tors 28 nov. 2024 kl 23:45 skrev Marc <Marc@xxxxxxxxxxxxxxxxx>: > >> > >> > >> > >> My ceph osd perf are all 0, do I need to enable module for this? > >> osd_perf_query?
