Unlike the performance monitors found in the Office Communications Server administrative tools, you cannot permanently modify the default set of performance counters for the performance monitors embedded in the Communicator Web Access snap-in. Although you can add and delete performance counters, your changes stay in effect only as long as the Communicator Web Access snap-in is running. If you close and then reopen the snap-in, each performance monitor reverts back to its default set of counters.

If you would like to routinely use a customized set of performance counters, you need to create a custom instance of Performance Monitor.
