Issue/Introduction
Guest Introspection service status shows as "Warning", for particular ESXi hosts
Removing and re-adding the host to the cluster does not resolve the issue.
Elements of GI do not prepare properly (vswitch creation, USVM may now power on, mux connect may not establish)
Exceptions found in the vsm.log of NSX manager regarding EventHistoryCollector object not being found:
2021-02-04 10:56:30.470 CET INFO VcEventsReaderThread VcEventsReader$VcEventsReaderThread:356 - - [nsxv@6876 comp="nsx-manager" level="INFO" subcomp="manager"] Caught exception:(vmodl.fault.ManagedObjectNotFound) { vsm.log- faultCause = null, vsm.log- faultMessage = null, vsm.log- obj = ManagedObjectReference: type = EventHistoryCollector, value = session[523efa74-####-####-####-########60c]52ae0944-####-####-####-########133, serverGuid = DAD00276-####-####-####-########ADB vsm.log-}
Environment
VMware NSX Data Center for vSphere 6.4.x
Cause
This issue can occur where the EventHistoryCollector ID cached internally in NSX was not updated in situations where the EventHistoryCollector object in vCenter has been destroyed due to an exception.
Resolution
This issue is resolved in VMware NSX Data Center for vSphere 6.4.11.
Workaround: To work around this issue, you can re-register NSX to vCenter and re-prepare the affected host(s) as required.
