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.
