The prometheus plugin currently skips histogram perf counters. The
representation in ceph is not compatible with prometheus' approach (iirc).
However I believe most, if not all of the perf counters should be exported as
long running averages. Look for metric pair that are named some_metric_name_sum
and some_metric_name_count.

specific data ( pools, capacity ..etc) is ?
Increasing log level for MGR showed only the following
