Monitoring nodes partecipating in the cluster

[marcopb]

Sorry for the question.. but I'm really a jboss newbie.

I've configured two machine to be part of a jboss cluster.
Now I've started one of this machine...
hoping I've well configured cluster-service.xml files on both jboss machine...
how can I monitoring if I have the cluster working well and how can I know how many nodes are in the cluster in a specific moment ?

I mean.. I start up the first node and I want to know there's only one node in the cluster.. then I start up the second node and I would like to know there're two nodes in the cluster ?

Thanks.

There is a JMX bean available that will display the nodes active in a cluster. I think the name of it is org.jboss.ha.framework.server.ClusterPartition.
You can get to it via the jmx console...

Yes.. .
I needed to go to jmx-console, search for jboss->service=MyPartitionName

thanks you..

Could you give an example of retrieving information from that mbean on the command line (i.e. via twiddle)? I've been trying to do something similar without the jmx-console and haven't succeeded. Thanks,

Let's assume you don't start JBoss with the -g switch, so your HAPartition is named "DefaultPartition".

For AS 5:

[bes@besdev bin]$ ./twiddle.sh get jboss:service=HAPartition,partition=DefaultPartition CurrentView
CurrentView=[127.0.0.1:1099]

For AS 4:

[bes@besdev bin]$ ./twiddle.sh get jboss:service=DefaultPartition CurrentView
CurrentView=[127.0.0.1:1099]

If you start with -g, e.g. "./run.sh -c all -g MyPartition" then replace "DefaultPartition" in the above with "MyPartition".
