Performance Counters
Microsoft Office Communications Server 2007 and Microsoft Office Communications Server 2007 R2 will reach end of support on January 9, 2018. To stay supported, you will need to upgrade. For more information, see Resources to help you upgrade your Office 2007 servers and clients.
The QoE Monitoring Server publishes media quality performance counters. These counters provide an objective measure of factors that can affect perceived quality of experience. These counters will exist for the following:
Location. Each monitored location that has sent a report. In the case of automatic discovery, the instance name will be the subnet. When imported locations are used, the instance name will be the location name. For details about locations and automatic discovery, see Specify Network Locations to Monitor.
A/V Conferencing Server. Each monitored A/V Conferencing Server instance that has sent a report. The name of the instance is the FQDN of the A/V Conferencing Server.
Mediation Server. Each monitored Mediation Server instance that has sent a report. The name of the instance is the FQDN of the Mediation Server.
Note
If a monitored location, A/V Conferencing Server, or Mediation Server does not participate in a call for 24 hours, its performance counter instances will be removed. Its instance will be created again when it participates in another call.
Table 3 shows a list of the available performance counters.
Table 3. Performance Counters
| Counter | Description | Applies to | Alerts Enabled |
|---|---|---|---|
Total number of audio calls |
Total number of audio calls Note In some cases, the number of calls that are reported by the system may not match the actual number of calls. For instance, if a call is made to a users computer but then is forwarded to that users mobile phone, then reports from two calls may be sent. |

No |
Percentage of audio calls with failed media connectivity |
Percentage of audio calls that fail to establish a media session |
Locations, A/V Conferencing Servers, and Mediation Servers |
Yes, when percentage exceeds 2% (default) |
Percentage of audio calls with "poor" Network MOS Degradation |
Percentage of calls where Network MOS degradation exceeds 1.0 (default) |
Locations, A/V Conferencing Servers, and Mediation Servers |
Yes, when percentage exceeds 2% (default) |
Percentage of audio calls with "poor" network MOS jitter factor |
