title: PM2 - How to exclude files changes, and watch for service failures only using the --watch flag
body: <p>I have a service which sometimes get some memory leaks from some unknown reason (still investigating).</p>
  <p>In the meanwhile to avoid from manually restart the service anytime it goes down I found the option of using <code>--watch</code> flag for that.</p>
  <p><strong>The problem</strong></p>
  <p>Using the <code>--watch</code> is also watching for file changes, therfore log files are trigger the watch action and the service restarts on any log change, or new files created.</p>
  <p>I'm looking for a way to exclude all files from any type and using the watch option only for watching if the service is down, so it will restart it automatically.</p>
