Under inventory, some e2e Nimsoft VM's are not listed - which are visible in the IM. Issue started after upgrade from 9.2 to 20.3.1. Other same type VM's under the same HUB are visible in the OC Inventory.The previous version 9.2.0 and that version of the Operator Console did not have this functionality.
Robot (VM) name in OC inventory did not change after Robot name was changed in IM for specific Robot.
Release : 20.3
Component : UIM - OPERATOR CONSOLE
As a workaround, clearing the Nimbus cache on specific Robots (VM's) following KB204236 (step 3) resolved the issue. The discovery_server_20.33 (that includes 20.30 T1) probe version with the code change to improve metric processing should also help to make sure that - this issue does not happen any more.
