Problem: I added that "Visualization and tracing of messages between
nodes" 4 years ago on the wiki.
Rather than adding new ideas we should work on a strategy to get it
done; some volunteer to lead it?
@Tomas : +1 to have a visualizer on the Infinispan Management Console,
but I'd also want to be able to enable a creation of such a trace
without needing to run a console.
For example it would be useful to have a utility method to use in our
unit tests, which is able to assert how many network round trips are
expected to be triggered by running the test. I think this would be
quite straight forward by injecting a custom JGroups protocol.

gigabytes of text-logs.

Then I can try to ask students at faculty if anyone would be interested.
