Challenge

The following alerts about handle counts on collector server are raised:

Health Service (Monitoring Host) Handle Count has exceeded the threshold

Health Service Handle Count has exceeded the threshold

User-added image

Cause

The monitors raising the mentioned alerts ensure that the "Process\Handle Count" counter for the "MonitoringHost.exe" and "HealthService.exe" processes does not exceed a specific threshold over a series of consecutive samples. If the conditions are met, this monitor will change to a critical state, which will then roll up to the "Health Service State" monitor.

In the Veeam MP case, the values that trigger the monitor may result from Collector server overload. If too many VMware hosts and VMs are monitored, then the Health Service may be overwhelmed when processing the data.

How to View Number of Handles

Current amount of handle counts can be checked using Windows Task Manager on the collector server:

Open Windows Task Manager and switch to the Processes tab.
Choose View -> Select columns and enable Handles.
After that you should be able to see a column named "Handles"

Solution

Please check configuration of SCOM Agent co-located with Veeam collector, see KB1026.

Make sure you don't have either of the following alerts, reference KB1765:

Veeam Collector: Health Service dropped data

Veeam Collector: Health Service workflows failed

If no additional alerts indicating performance issues with SCOM Agent occur, you can try increasing thresholds for 2 monitors based on current number of handles:

For MonitoringHosts.exe adjust "Veeam Collector: Health Service (Monitoring Host) Handle Count threshold"
For HealthService.exe adjust "Veeam Collector: Health Service Handle Count threshold"

Otherwise you may consider moving VMware monitoring jobs to other Veeam Collectors or co-locating Veeam Collector with a SCOM Management Server.
