Debug help

[Nick S]

Hi,

I would like to write a separate module, which would catch/indicate, when some functions are executed in other modules.

For example,

otp/gen_server

handle_call(new_msg,...)            %% do not catch this line

handle_call(....) ->                       %% catch this line i.e. when all above conditions doesn't match.

Which debug tool would be best for my needs?
Also would like to include some timing measurements, later on.

Nick.

Hi Nick,

For such a purpose, I'd take gen_event [1] and/or the dbg module [2], and erlang:statistics might also be of some help here. Since I'm quite new to Erlang, I'd be very interested in more/other suggestions, too.
