Comment 1 Juan Luis de Sousa-Valadas 2020-10-06 10:04:25 UTC
Increasing priority to urgent because we want this verified so that we can try to get it merged in 4.6.0 soon.

Steps to  verify:
1- launch a 4.6 OVN cluster
2- login into prometheus (prometheus as in "http://prometheus-k8s-openshift-monitoring.<route default subdomain>" , not grafana)
3- Go to status -> targets
4- Look for the two OVN targets (just control+f ovn) and check that both have state UP

Comment 2 Juan Luis de Sousa-Valadas 2020-10-06 14:12:08 UTC
Lowered to medium because the 4.6 bug already merged.

Comment 4 Dan Brahaney 2020-12-04 18:49:08 UTC
No alerts are triggered. Verified.

Comment 5 Dan Brahaney 2020-12-04 18:52:52 UTC
OVN targets in prometheus also all have status UP.
