After installing the APM Agent, enabling JMX monitoring and also set introscope.agent.jmx.compositedata.enable=true, users are unable to collect metrics for attribute memoryUsageAfterGc under JMX MBean java.lang:type=GarbageCollector
The metrics for "memoryUsageAfterGc" in JMX MBean attribute are TabularData as below screenshot shows.
APM 9.x, 10.x
Weblogic 10.x, 11.x, 12.x
The TabularData is outside of the current design for APM Agent JMX monitoring.
