Rails real time app

I am trying to build real time app using Ruby and Rails.

Task (long story short): user submits jobs(fetching, pulling with interval - not a one-time shot), that evaluates on server (some background processing). The status of jobs can be monitored on web (probably WebSockets for this).

I'am confused how to implement it right, within already developed ecosystem of frameworks and libs (trying not to invent "bicycle").

Will really appreciate any related info (articles, books, etc.)
