"Objects are not receiving data from adapter instance" triggering on vCenter adapters due to Entity Status objects

Products

• VMware Aria Suite

Issue/Introduction

• The "Objects are not receiving data from adapter instance" alert continually triggers for vCenter adapter(s)
• Clicking the Show Objects link in the alert details provides a list of Entity Status object types named PoweredOn:<vCenter_name>, PoweredOff:<vCenter_name>,Template:<vCenter_name>
• Cancelling the alert results in the alert re-triggering on the next collection cycle

Environment

Aria Operations 8.17.1
Aria Operations 8.17.2
Aria Operations 8.18

Cause

• Entity Status objects are internal constructs created to increase performance when grouping objects in specific states (i.e powered on/off VMs)
• Entity Status objects are named to match the vCenter name
• When vCenter name changes, new Entity Status objects are created with the new name
• Entity Status objects with the previous vCenter name are not removed and enter No Data Receiving status
• The "Objects are not receiving data from adapter instance" alert in 8.17.1 and newer triggers based on the Number of No Data Receiving Objects metric on adapter instances
