Challenge

The vCenter Database utilizes most of the available CPU, impacting vCenter Server performance. Stopping nworks Collectors brings the CPU usage back to normal. The nworks vmspi log shows the following errors:

VCEVT+** [VC250] retrieveEvents: createFilter failed, System.Net.WebException: The operation has timed out

Cause

nworks can use a vCenter-side event filter to reduce the traffic back to the Collector. The filtering, however, turns out to impact vCenter Database performance.

Solution

In nworks 5.6 and later, creation of the event filter is disabled by default. However, if the issue described above occurs, you will need to turn off the setting manually:

In nworks Web UI, go to the Enterprise Manager tab, select the Collector in the hierarchy on the left and click Advanced settings.
Find the EnableVcVerboseFilter setting and set it to False.
You will be prompted to restart the Collector. To do that, select the Collector and click the Restart button.

Applied changes will not influence monitoring accuracy.
