Message Queuing 5.0 Management Pack for Operations Manager 2007

Message Queuing (also known as MSMQ) was developed to be a server application that enables applications to communicate across heterogeneous networks and systems that may be temporarily offline or otherwise inaccessible.
Instead of an application communicating with a service on another computer, it sends its information to Message Queuing, which sends the information to a Message Queuing service on the target computer where it is made available to the other application. Message Queuing provides guaranteed delivery, efficient routing, security, and priority based messaging.
