Why?
Distributed Erlang offers great tracing and debugging flexibility around standard functions. This project was originaly made to solve a file descriptor leak on a rabbitmq server in production. The idea is to set a passive node, connect to an active node, and, by using rpc call ensuring all opened/closed ports are well opened/closed.
