- alexgaribay 10y agoErlang has Observer, a built in tool that lets you monitor and trace things as well as well see your process hierarchy.
- davidw 10y agoI'm often not much of a GUI tool guy, but Observer is really cool - the GUI really does give you a nice view of how the supervision tree of a more complex Erlang system is put together.
- bobwaycott 10y agoYep. Not only that, but I find it to just be insanely fun to go double-clicking with wanton abandon throughout Observer, digging in to everything just because I can. That it's all there, with no setup and effort required, makes it feel almost magical.
- rdtsc 10y agoOthers mentioned Observer. That is very cool. When without a GUI I use the built-in dbg module. Sometimes via the recon_trace wrapper to get the tracing to be rate limited (if on a production cluster). ttb built-in modules used for tracing on multiple nodes, capture more data and then save to a file and inspect later. eflame or eep (not the Erlang Proposal, the profiling tool) + kcachegrind to view results.
