title: Ruby on Rails start additional script on server startup
body: <p>This is a pretty basic question, I tried searching but the question is a little obscure for Google searches. </p>
  
  <p>When I start my rails server I want it to additionally start a script I wrote that just gives a feed of different system resources (i.e. CPU usage, incoming &amp; outgoing connections, as well as alerts if resources get to high, etc.) Preferably it starts in a separate terminal windows.</p>
  
  <p>Additional information if it helps any:
  OS: Kali Linux 
  Ruby: 2.0.0
  Rails: 4.0.3
  WEBrick: 1.3.1</p>
