Use Channel.setInfo() to provide data to JGroups probe
------------------------------------------------------

                 Key: JBAS-5090
                 URL: http://jira.jboss.com/jira/browse/JBAS-5090
             Project: JBoss Application Server
          Issue Type: Feature Request
      Security Level: Public (Everyone can see)
          Components: Clustering
            Reporter: Brian Stansberry

            Priority: Optional


Think about ways to take advantage of following from Bela Ban:

Okay, I've added an "info" paremeter to Probe, so you can run

JGroups/bin/probe.sh -timeout 1000 -query info

and this will dump *any* information that was added via Channel.setInfo(String key,Object val). The val will be written to a StringBuilder, so make sure you place only values into info which have a meaningful toString().


This can be used to dump buddy replication information.

However, any application which has access to a channel can add information which is useful on a probe, e.g.

   * JBossCache
         o Version
         o Buddy replication info
         o Number of nodes, attrs
         o Config info
   * Clustering
         o Different clusters a node is part of
         o Node name
         o Config info

The Probe utility is quick and dirty and - since it uses IP multicasts - cannot dump more than 65K worth of data, so make sure you don't cram everything in there ...
