Which metric has to be Monitored in JVM to monitor JBoss Server Memory hike

[arun2arunraj]

Hi Developers,

    In JBOSS AS Plugin, there is an jvm resourceType. In that there are 3 metrics. ( JVM Free Memory, JVM Total Memory, JVM Max Memory ).

    Which metric will be useful for me to monitor whether my jboss application is getting memory hike. Please guide me to analyze the rhq result.

    AFAIK, These three metric will not help to finding memory hike problem. Because, these three will only tell me the memory utilization. If I am wrong, Please guide me.

    So, Then How could I monitor the current memory hike in my JBoss via RHQ.

Which version of the JBoss server are you talking about?

[arun2arunraj]

Hi Thomas

JBossAs Servers Plugin in RHQ 4.7 :

              JBoss Server Version : 4.0.5GA and 7 (please share your knowledge for these two versions).

              More over, In RHQ 4.7, We dont have JVM instead we are having JBoss Cache SubSystem. Why we are having JBoss Sub System ? ? ?  Please guide me.

Arun,

This has been asked recently, have a look at this thread: https://community.jboss.org/thread/227806?tstart=0

Not sure what you mean with JBoss Cache SubSystem

Hi Thomas,

    Thanks for the cool discussion. Me too expecting.

IN RHQ 4.6

In the image, there is an JVM Resource in JBoss servers. It has Memory Subsystem. It owns Garbage Collector which you have talked in the thread.

But It was missing in RHQ 4.7. Instead it has JBoss Cache Manager. Is there any reason for removing JVM and inserting Jboss Cache SubSystem.

Arun,

The screenshots show two different inventories, from two different versions of RHQ.

In your QA_APP3 environment make sure your JBoss servers are started with the "-Djboss.platform.mbeanserver" system property.

Yes Thomas,

       These are all two different agents as well as two different RHQ Versions (4.6 , 4.7).

       In RHQ 4.6,  JBoss AS Plugin is having JVM monitoring.

       In RHQ 4.7 , JBoss AS Plugin is having JBoss Cache subsystem. Why you guys have updated it is my question .

       I am not awared about "-Djboss.platform.mbeanserver" property. I am searching for it. If you are having best tutorial to understand it, please share it with me.
