Description Standa Laznicka 2020-10-12 12:38:59 UTC

Description of problem:
The metrics of the oauth API servers' service are not being scraped by Prometheus and therefore don't appear in results of Prometheus queries

Version-Release number of selected component (if applicable):
4.6

How reproducible:
100%

Steps to Reproduce:
1. Go to Prometheus console
2. either
a) attempt to query apiserver metrics and look for oauth-apiserver
or
b) go to Status/Targets and look for oauth-apiserver 

Actual results:
no oauth-apiserver

Expected results:
being able to see the oauth-apiserver in Prometheus targets and query its metrics

Additional info:
it's because the CAO does not include ServiceMonitor for the oauth-apiserver in its manifests

Marking as verified, able to see the oauth-apiserver in Prometheus targets and query its metrics.
