I need trace all user interactions with a AJAX page as well as functions invoked by the interactions if there are. If a function is asynchronous, I also need record the starting time and the ending time. I'm new to DTrace, and not sure (1) whether and how I could do it using DTrace, (2) what the performance overhead would be, and (3) would it be possible to transfer the trace logs/records back to the server side and what the performance overhead would be if it can be done? Thanks!
