title: How to get logging working with pm2 and Heroku
body: <p>Is there a way to tell pm2 to leave stderr and stdout alone (as opposed to writing to files)? </p>
  
  <p>I'm using pm2 on Heroku using <a href="https://gist.github.com/Unitech/4c8ea564aa8bf0a389c5" rel="noreferrer">this gist</a> as my model. Everything seems to work perfectly except that I've lost any ability to log from within my app. They don't show up in the Heroku logs and the files that pm2 creates aren't accessible to me on Heroku's file system (or I can't find them).</p>
