Expected metrics are unavailable in Team Center.
The following errors are repeated in the notification panel:
Release : 20.2
Component : Introscope
Looks like either NASS was not reachable or the GW was not in sync with NASS. So best course of action is to restart the pods.
The pods to restart are:
apmservices-nass-001-6949c97564-l9vh2
doi-nass-indexer-56bc84b594-jhctt
I see this in NASS log:
2021-10-26 18:38:46.148 ERROR [nass,090104c6ee74469a,090104c6ee74469a,false] 1 --- [ Scheduler-3] c.c.a.c.s.SupportabilityManagerPoller : No instances available for metadata
Restart this pod as well
