Exchange 2007 Unified Messaging Role Counters

Version 2

    This template contains advanced performance and statistics counters for monitoring Exchange 2007 Unified Messaging Role. Some of the counters may require manual configuration, such as setting up installation-specific instances, correcting thresholds for the client’s environment, and so forth. Use this template in addition to the Exchange 2007-2010 Unified Messaging Role Service and Counters (Basic) template.
