The MSMQ Queue object contains performance counters you can use to monitor message statistics for the selected queue. There are instances for each queue on the computer. If an MSMQ-based application has a private queue open on another computer, an instance for that queue is also available. The instance name of these queues is the format name of the queue. If an MSMQ connector application is running on the computer, an instance is available for the MSMQ connector queue. The queue name is displayed as foreign=GUID.
Instance lists only the first 97 queues created on the computer, including private queues.
Note The Computer Queues instance represents the computer's source-journal and dead-letter queues. The Bytes in Queue and Messages in Queue counters monitor the computer's dead-letter queue. The Bytes in Journal Queue and Messages in Journal Queue counters monitor the computer's source-journal queue.
Temporary queues are easily identifiable because the computer name in the instance does not match the name of the computer on which they reside.
