Performance event statistics
The performance event data in the event message contains statistics about the event. Use the statistics to analyze the behavior of a specified queue.
The event data in the event message contains information about the event for system management programs. For all performance events, the event data contains the names of the queue manager and the queue associated with the event. The event data also contains statistics related to the event. Table 1 summarizes the event statistics that you can use to analyze the behavior of a queue. All the statistics refer to what has happened since the last time the statistics were reset.
|TimeSinceReset||The elapsed time since the statistics were last reset.|
|HighQDepth||The maximum number of messages on the queue since the statistics were last reset.|
|MsgEnqCount||The number of messages enqueued (the number of MQPUT calls to the queue), since the statistics were last reset.|
|MsgDeqCount||The number of messages dequeued (the number of MQGET calls to the queue), since the statistics were last reset.|
Performance event statistics are reset when any of the following changes occur:
- A performance event occurs (statistics are reset on all active queue managers).
- A queue manager stops and restarts.
- The PCF command, Reset Queue Statistics, is issued from an application program.
- On z/OS® only, the RESET QSTATS command is issued at the console.
