    Description

      This is a clone of issue OCPBUGS-1453. The following is the description of the original issue:
      —
      Description of problem:

      TargetDown alert fired while it shouldn't.
Prometheus endpoints are not always properly unregistered and the alert will therefore think that some Kube service endpoints are down

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

      The problem as always been there.

      How reproducible:

      Not reproducible.
Most of the time Prometheus endpoints are properly unregistered.
Aim here is to get the TargetDown Prometheus expression be more resilient; this can be tested on past metrics data in which the unregistration issue was encountered.

      Steps to Reproduce:

      N/A

      Actual results:

      TargetDown alert triggered while Kube service endpoints are all up & running.

      Expected results:

      TargetDown alert should not have been trigerred.
