Jboss 4.2.3 JVM Monitoring

[Vikram Saxena]

Hello,

My application is deployed on JBoss 4.2.3 and I need to monitor the JVM (Free Heap Memory) and produce a graphical representation.

I have tried to use the JConsole, which comes with the JDK but I cannont be monitoring the screen forever. Though it is very good and detailed but I would need a report generating script.

Do we have inbuilt monitoring for JBOSS ?
Can we get continuous JVM Memory logging for JBOSS ?

Waiting for some suggestions. Thanks

Well you can add some command line params to have garbage collection stuff be posted to the terminal window where you start up you app server.

But to me the best way is with the JOPR project, or JBoss Operations Network, which is built upon JOPR. They are JBoss products, one is the open source project, with some limitations, and one is the support contract one, where you pay for it, but has monitoring and graphs.

go through jopr at jboss.org/jopr ... most probably that is what you are looking at...

I got the thing i was looking for. I needed to create a UNIX script which would monitor the JVM memor parameters for me.
This is how anyone wanting the same can do it :

./twiddle.sh --server=jnp://$HOST:$PORT get "jboss.system:type=ServerInfo" FreeMemory | grep FreeMemory
./twiddle.sh --server=jnp://$HOST:$PORT get "jboss.system:type=ServerInfo" MaxMemory | grep MaxMemory
./twiddle.sh --server=jnp://$HOST:$PORT get "jboss.system:type=ServerInfo" ActiveThreadCount | grep ActiveThreadCount

The twiddle script is located at $JBOSS_HOME/bin


Cheers !
