Bug #42961
osd: increase priority in certain OSD perf counters
0%
Description
There are reports from users missing stats in dashboard/prometheus mgr modules about the following perf counters:
"bluestore_compressed", "bluestore_compressed_allocated", "bluestore_compressed_original",They all are tagged as priority 0 (PRIO_DEBUGONLY), and ceph-mgr filters (by default) out any perf counter below 5 (PRIO_USEFUL). There are 2 possible approaches here:
- Ad-hoc fix by increasing the priority for these specific perf counters from 0 to 5.
- Longer term one: by providing a mgr option to cherry-pick perf counters of lower than default priority and export them.

Ernesto, while we are at it, are there any other specific stats that you've gotten requests for?

Neha, not that I know of. This comes from a downstream BZ (https://bugzilla.redhat.com/show_bug.cgi?id=1679924) and a customer ticket. Perhaps, we could move the discussion to users & customer facing experts, as they would probably know better what stats they missed in Prometheus/Dashboard. I'll send a mail to ceph-users on this regard. Nevertheless, I think we can go with this as it is.
Thanks a lot for taking care of it!
