Description Paul Cuzner 2020-09-25 01:32:45 UTC
Description of problem:
mgr/prometheus exposed per pool statistics that does not include the compression information


Version-Release number of selected component (if applicable):


How reproducible:


Steps to Reproduce:
1. curl http://<mgr>:9283/metrics
2. 
3.

Actual results:
In the output the ceph_pool_* statistics do not include compress_bytes_used or compress_under_bytes


Expected results:
mgr/prometheus should include the compression stats per pool, like this.
