Richard Achmatowicz commented on JGRP-324:
------------------------------------------

I've created a new CVS project for the JGroups Wireshark plugin on SF under the name wireshark-plugin and uploaded a *draft* version of the plugin to SF.
You can visit the project at http://javagroups.cvs.sourceforge.net/javagroups/wireshark-plugin. The project contains the sources for the plugin, some sample Wireshark capture files  created using the JGroups Draw application, and instructions on how to get the plugin working with Wireshark.

This plugin has been only minimally tested over UDP, and will be subject to continued development over the next couple of months. Up until the time we feel it is stable and release a "version", please keep in mind it is in a state of development and use is "as is".

A few points:
1. The plugin should be able to display complete JGroups bundles (i.e. the TP header, all Messages in a  bundle, as well as all Headers within a Message.  At present, only TP and PING headers are fully processed; for the others, we just display the header key (e.g. STABLE) and the header size.

2. There is a user preferences section available from Edit->Preferences->Protocols->JGroups. The main options here you will need are:
(i) telling Wireshark which port to associate with JGroups messages
(ii) turning on debugging fields - which show pretty much all fields in the JGroups Message, as opposed to those which users would really be interested in.

The next immediate development steps will be trying to get the UI presentation right and then testing over more JGroups configurations. Later development will deal with handling Wireshark conversations.
