IBM MQ has always been able to generate event messages when something “interesting” has occurred in the queue manager. These events could be showing that a queue is full, or that there has been an authorisation failure; someone needing an audit trail might want to capture the command and configuration events. These events are written as MQ messages to well-known queues, using PCF structures which can be decoded to give the full description of the event.
