You use Performance Monitor counters to monitor Chat Service activity. For this purpose, Chat Service provides several client-to-server and server-to-server counters to indicate whether Chat Service is processing data. When these counters approach zero, Chat Service either has little or no data to process (that is, few or no requested client connections), or the service is not functioning properly.
