What performance events are
Performance events are related to conditions that can affect the performance of applications that use a specified queue.
The scope of performance events is the queue, so that MQPUT calls and MQGET calls on one queue do not affect the generation of performance events on another queue.
Performance event messages can be generated at any appropriate time, not necessarily waiting until an MQI call for the queue is issued. However, if an MQI call is used on a queue to put or remove a message, any appropriate performance events are generated at that time.
Every performance event message that is generated is placed on the queue, SYSTEM.ADMIN.PERFM.EVENT.
The event data contains a reason code that identifies the cause of the event, a set of performance event statistics, and other data. For more information about the event data returned in performance event messages, see:
