How To MSMQ: Get Extended Trace Information from MSMQ Triggers When You Use Trigmon (255553)

MORE INFORMATION

WARNING: If you use Registry Editor incorrectly, you may cause serious problems that may require you to reinstall your operating system. Microsoft cannot guarantee that you can solve problems that result from using Registry Editor incorrectly. Use Registry Editor at your own risk.

When logging or tracing is turned on in the MSMQ Triggers service, tracing messages are created as MSMQ Messages. These tracing messages are sent to the private "Msmqtriggerslog" queue, and then the messages are monitored by the Trigmon application (or any other application that chooses to monitor this queue). If there is a large amount of activity in the Triggers service, and the tracing messages are not being removed from the queue, then tracing messages accumulate in the queue and take up space.

You activate the Triggers service logging mechanism when you use the MSMQ Triggers MMC Snap-in, as demonstrated in the following examples:
