Description

there are some additional PG and OSD related metrics that would be helpful to monitoring that are available, but current not exposed. This feature request proposes the addition of

a count of primary pg's by osd (increase priority of numpg_primary from 0 to 8
a count of pg's with snaptrim qlen > 0 by pool
a summary of the usage by pool on each osd (from pg dump pool_statfs section)

This could be achieved by updates to
src/osd/osd_perf_counters.cc
src/pybind/mgr/prometheus/module.py
