This section summarizes the managed SIP stack performance counters that are available with UcmaRedist.msi (Microsoft Office Communications Server 2007, Unified Communications Managed API v1.0 Redist).

About the managed SIP stack performance counters

Performance counters allow you to monitor specific aspects of work performed by your application, and can help you identify and troubleshoot performance issues.

The managed SIP stack performance counters are provided by the following files, which can be found in the SDK\Core\Bin directory under the Microsoft UCMA 3.0 installation directory:

  • S4Perf.dll

  • S4Perf.ini

  • S4Perf.h

Note

The same files are copied to the UCMA v1.0 SDK directory under the Microsoft Office Communications Server 2007 installation directory when you install UCMA v1.0 SDK (UcmaSdk.msi).

The counters listed in this topic fall into one of two categories: PERF_COUNTER_LARGE_RAWCOUNT or PERF_COUNTER_LARGE_BULK_COUNT. Counters whose CounterType is PERF_COUNTER_LARGE_RAWCOUNT show the last observed value, not an average. Counters of type PERF_COUNTER_BULK_COUNT show an average number of operations per second. For more information, see Counter Types.

Installing and configuring the managed SIP stack performance counters

The managed SIP stack performance objects and counters are installed when UcmaRedist.msi is executed. If necessary, an application can unregister these performance objects similar to the way shown in the following command line.

regsvr32 /u /n /i " C:\Program Files\Microsoft UCMA 3.0\SDK\Core\Bin \s4perf.dll"
