Can't monitor webapp's JVM in JBoss EAP 6.2 (Domain mode)

[ranmses]

Hello,
For the last couple of days I've been trying to monitor all the JVM's in our JBoss system.
We have 3 working VM (CentOS 6.5) in domain mode (1 master + 2 slaves).
As I type, that's the current situation:

• Master: 2 JVM processes, 1 host controller + 1 process controller

• Slave 1 : 3 JVM processes, 1 host controller + 1 process controller + 1 webapp (deployed jar)

• Slave 2 : 3 JVM processes, 1 host controller + 1 process controller + 1 webapp (deployed jar)
  There' s one jmxetric xml file for each JVM. The problem:

  We cannot make the webapp JVM's to be monitored. The 6 others are correctly monitored.

For each one of the xml files I uncommented the lines below:

           <mbean name="jboss.as:subsystem=web,connector=ajp" pname="ajp">
                  <attribute name="requestCount" type="int32" slope="positive"/>
           </mbean>

All JVM processes show references of oncrpc-1.0.7.jar, gmetric4j-1.0.7.jar and jmxetric-1.0.6.jar, with apparently correct configurations. Tried to increase the delay at the xml file, but no luck.

Any ideas?

Best!

This Github bug tracker is only used for tracking confirmed bugs.

This looks more like a "how do I?" support request, please ask on the ganglia-general mailing list or possibly the JBoss user forum.

Two suggestions I can make:

• check you have a distinct for each JVM on the same host, if two JVMs are on the same host they must not use the same process name there.
• use lsof to check the JVM process to see if the jmxetric code opened a socket

Ok, sorry for the wrong request.

Yes, there's one xml with a unique process name for each JVM. I already have 2 different JVM being monitored at each one of the 3 hosts.

The problem is with the third JVM, which supports a webapp from a deployed jar file.

Will check if the socket is being open, but I suppose not since there's no sign of the metric with 'telnet localhost PORT'.

Well, thank you anyway.
