Microsoft Office Communication Server 2007 R2 SCOM Pack QoE Monitoring provides media quality monitoring for Mediation Server, for A/V Conferencing Server, and for Location. However, if you have more than 100 instances for each category (Mediation Server, A/V Conferencing Server, or Location), some of instances do not appear in the SCOM console.
SCOM QoE Monitoring uses performance counters that are published by the Office Communication Server Monitoring Server.

Microsoft has confirmed that this is a problem in the Microsoft products that are listed in the "Applies to" section.
The SCOM agent has memory usage thresholds. By default, the limitation on memory in both Health Service and Monitoring Host is 100 MB private bytes. This means that Health Service or Monitoring Host can use 100 MB at most.
We recommend that you increase the threshold if you want to monitor more than 250 instances (including Mediation Server, A/V Conferencing Server, and Location) or if you notice that the following event is logged:
Event Type: Warning

Time: 10:29:16 AM
Description: RestartHealthService.js : Restarting Health Service. Health Service exceeded Process\Private Bytes threshold.
