I wrote code for https://github.com/apache/skywalking/issues/4841 which does what Mandar is looking for. I could submit a PR for that but I'm curious what type of disasters are expected from this type of functionality. The code I'm using skips getters/setters, methods added by AOP, etc as those can be sensibly skipped. Do you think that makes it less disastrous or does the issue stem from possibly monitoring user code which is called too frequently?
