Description Flags
prometheus raph showing the slow_ops metric none

Description Paul Cuzner 2020-10-06 01:49:07 UTC 
Description of problem:
Although osd's track slow ops and bubble this up to mgr, the metrics that mgr/prometheus generates does not include alert related metrics. This BZ


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


How reproducible:
100%

Steps to Reproduce:
1. Generate SLOW_OPS by lowering osd_op_complaint_time
2. run rados bench to trigger the health check
3. no field in the prometheus scrape exposes this condition

Actual results:
SLOW_OPS triggers a health status change (0->1), but does not provide any information related to slow_ops

Expected results:
SLOW_OPS should be visible in the prometheus data

Hi Josh, Is it targetted for 4.2z1. If not can we move this to 4.2z2?

Checking with Paul to verify the test setup. Also adding @jefbrown .

If it is confirmed to be an issue I think we should move it to z2.

Can we have this BZ moved to Verified and raise a new BZ to track alerts?
