How to implement starting and listening for external processes in Ruby?

Question

ruby

Hello! The task is to implement an application in Ruby that launches external processes, monitors their state and listens to STDOUT and STDERR streams.
I found something similar in Python using Twisted Reactor.
And what to use in Ruby? I found only EventMachine, but I don’t understand how to implement my task using it.
