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.

I personally feel that Infinispan Management Console could be possibly the right "platform" where to gather, store and visualize such a kind of information. This can also be used for demonstrative purposes (but not only!).

Radim's intention was mainly driven by the idea of having ability to see inter-node communication clearly in order to be able to find corrupted message/data flow and spot complicated bugs while one does not need to grep through gigabytes of text-logs.
