title: How can I monitor Heroku multi-dynos app with Prometheus?
body: <p>I need monitor apps deployed to Heroku by Prometheus monitoring system.</p>
  <p>Problem is that if you have more dynos app, you need to know all IP address of your dynost to be able to pull metrics from all dynos.</p>
  <p>For K8s or AWS we are able to get full list of PODs/instances, So you are able to do this.</p>
  <p>So question is, do you know, how to get IPs of all dynos from Heroku?</p>
