I'm not sure if that's the canonical repository -- maybe Ulf can weigh in.
It's tempting, but I find it's best not to mess with the vanilla
supervisory facility and instead use gproc for getting a list of named
processes. You can also use gproc to publish interesting process stats
to consumers, thus avoiding costly and intrusive queries to the
