One of the drawbacks of JMX is the lack of cluster support, you have
to invoke the operation in each one of the servers. The solution? use a
JMX client that does that for you, as jManage.
You setup the servers as in any other administration console and then
you can group them in clusters, allowing you to see the value of the
properties in each one of the servers in the cluster and invoke operations
in all of them getting the results of each server in a single page.
