Collecting performance data for one or more specific entities has caused the performance data request to the vCenter to fail. No further performance data will be collected for these entities. Please review the status of these entities in the VMware Environment and address any serious issues that may have occurred. Once the entities are operating normally, they can be removed from the Agent-Managed Blacklisted Entities list and performance data collections will resume for the entities. Consult the Foglight for VMware documentation for the procedure for removing an entity from the Agent-Managed Blacklisted Entities list.

Possible solutions:

•

Resolve any errors with these entities in the virtual environment.

Collecting performance data for 25 or more specific entities has caused the performance data request to the vCenter to fail. Due to the size of this number it is likely that an issue with the virtual environment is the root cause and these entities are not specifically at fault. Please resolve any known environment issues. If the situation continues, please contact Quest Support.

Possible solutions:

•

Resolve any known environment issues.

An unexpected issue occurred during data collection from the vCenter. Please review your environment to ensure that data collection has resumed in a normal fashion. If there is a persistent problem or this message recurs regularly please contact Quest Support.

Possible solutions:

•

Confirm that the VMware data collection resumed after the issue was encountered by the agent. If the Foglight installation is not receiving VMware monitoring data or this message occurs regularly, contact Quest Support.
