Cause

In VCF Operations, you may receive frequent "Objects are not receiving data from adapter instance" alerts for non-critical or temporary objects (e.g., Veeam backup datastores or transient virtual machines). These alerts are often noise, as these objects are not intended for continuous monitoring.

Resolution

This is a known issue with VCF/Aria Operations
There is currently no resolution.  Use the steps detailed in the workaround section.
