Microsoft Exchange Performance Counters

Microsoft Exchange Unified Messaging Auto Attendant Performance counters

There are many performance counters that can be used to maintain and troubleshoot a Microsoft Exchange Server 2010 Unified Messaging (UM) server. Unified Messaging performance counters are used to measure quantities of information or data for Unified Messaging based on the number, size, duration, and rate of data that's being requested or received. The MSExchangeUMAutoAttendant performance object can contain multiple instances. The number of instances for the performance object depends on the number of UM auto attendants that are created in the Exchange organization. Object: MSExchangeUMAutoAttendant
