MSMQ Monitor is only available with Enterprise Version.

MSMQ Monitor assumes that Message Queue should be always empty. 
When it is not empty it records the arrival time of the first message.
When the arrival time of the first message changes it fires the event.
(It happens when some software removes all messages and a new message arrives)
