Yes, like crocodile clips for a circuit board, I can insert a probe into a circuit and see what's on the wire.

When your callstack is 50 methods deep and there's 20 layers involved and marshalling and it's difficult to see what is going on.

I want to mark two pieces of code and see the data structures passing through them, similar to a debugger but more like a log file or trace like Jaegar or Kibana. But the actual POJO or JSON objects themselves.

This is a great analogy and captures what I meant very clearly! It would be awesome to pinpoint two pieces of code and ask for the execution flow visualizer for that path :)
