MQ Monitor - Enqueue/Dequeue Counts seem low

Products

• CA Application Performance Management Agent (APM / Wily / Introscope)
• INTROSCOPE

Issue/Introduction

 Problem:

 After installing a new APM MQ Agent, the total enqueue/dequeue counts reported are too low.

 

 Environment:

 Any version of IBM MQ being monitored by multiple monitoring applications or any version of APM MQ Agents

 

Cause:

 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.

 

Resolution:

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
