JMS metrics do not display after enabling the MQ Error Detector pbd which is part of the MQ Powerpack for Java Agent.
The issue is due to the below directives specified in webspheremq_errors.pbd. These prevent standard JMS metrics reported by the core Java Agent from displaying in the Investigator.
SkipMethodForFlag: JMSPublisherTracing publish
SkipMethodForFlag: JMSSenderTracing send
SkipMethodForFlag: JMSListenerTracing onMessage
SkipMethodForFlag: JMSConsumerTracing receive
To typically resolve the issue, comment out (i.e. put a # in front of line) or remove those directives from webspheremq_errors.pbd, save the changes and restart the Application Server.
