Queues usually process and go to zero quickly. Queue depth is the number of messages on the queue. The default maximum queue depth is 5000. If the depth of any queue is greater than zero during idle time or greater than 60 percent of the maximum queue depth during a heavy load, then that indicates a problem.
For Windows® operating
systems:
If the depth of queues do not decrease to zero after a certain period, then sensor events are not being consumed by the WebSphere Sensor Events server. Check the SystemOut.log file in the WAS_PROFILE_HOME\logs directory to see if an exception occurred.
To check the queue depth on Linux® operating systems, run this command:
export AMQECLIPSE=/opt/mqm/ies30/eclipse /opt/mqm/bin/runmqcfg
For more information on queue depth, see the WebSphere MQ Information Center.
