> To use JGroups JChannel JMX monitoring, it's needed to register it to a MBeanServer.
> Would it be possible to add a configuration key to be able to monitor the cache at a network level ?
> Here's the actual JGroups documentation to activate JMX monitoring programmatically : http://community.jboss.org/wiki/JMX
> I guess the correct place to implements the feature should be located in org.infinispan.remoting.transport.jgroups.JGroupsTransport::startJGroupsChannelIfNeeded()
> and implementation could look like that :
> protected void startJGroupsChannelIfNeeded() {
>         if (startChannel) {
>             try {
>                 channel.connect(configuration.getClusterName());
>                 // my first contribution M Lachance
>                 ArrayList servers = MBeanServerFactory.findMBeanServer(null);
>  
>                 if (servers == null || servers.size() == 0) {
>                     log.log(Logger.Level.WARN, "No Available MBean Servers");
>                     //throw new Exception("No MBeanServers found;" +
>                     //        "\nJmxTest needs to be run with an MBeanServer present, or inside JDK 5");
>                 } else {
>  
>                     MBeanServer server = (MBeanServer) servers.get(0);
>                     try {
>                         if (server != null) {
>                             JmxConfigurator.registerChannel((JChannel) channel, server, "JChannel=" + channel.getChannelName(), "", true);
