Using CA APM infrastructure agent Release 22.214.171.124 with the JMX bundle to instrument one of our JVMs serving a Hadoop component. After the instrumentation and remote JMX port enabling on the JVM, we are able to get the thread related metrics, but we are unable to get information on the heap usage for the JVM in CA APM. When we use Jconsole to view the jmx metrics, we can see the heap usage.
Request you to check why heap usage is not being reported using CA APM.
Also what metrics can we get with the Remote JMX extension?
Release : 14.6
Component : APM Agents
1. Remote JMX is a generic extension to pull and report JMX data. Other than some standard Mbeans (Thread, OS, GC) from JVM, the agent doesn't know in advance which Mbeans we will be fetching data from.
2. The reason why we do not provide heap data OOB is that heap data returned by JMX is wrapped in a special object which we need to transform to get raw data.
