> 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 ...
