After installing a new APM MQ Agent, the total enqueue/dequeue counts reported are too low.
Any version of IBM MQ being monitored by multiple monitoring applications or any version of APM MQ Agents
Multiple applications monitoring MQ enqueue/dequeue counts will actually interfere with each other. These counts are cleared by MQ after they are reported to the monitoring application. As a result, each monitoring application can only get part of the true count.
Do not have multiple APM Agents (or APM and another application) try to monitor MQ at the same time. One of the monitoring applications (or APM Agents) should be disabled
