Uses Heroku's unofficial buildpack.

More configuration to get it to actually deploy to Heroku. I've blogged about this here: https://rohitmacherla.com/installing-prometheus-on-heroku. Perhaps you'd like to look at some advanced monitoring techniques for Salesforce.com as part of the blog series?

Simplest option:

1. Login to Heroku via CLI

2. Run

   heroku create --buildpack https://github.com/heroku/heroku-buildpack-prometheus.git

3. It will create a Heroku app, sets the buildpack and gives us a git URL for the repo like this:

   Creating app... done, ⬢ shielded-beach-38076
   Setting buildpack to https://github.com/heroku/heroku-buildpack-prometheus.git... done
   https://shielded-beach-38076.herokuapp.com/ | https://git.heroku.com/shielded-beach-38076.git

4. Copy the Heroku git repo URL. In our example, that's https://git.heroku.com/shielded-beach-38076.git

5. Clone the current repo to your local machine git clone https://github.com/markgarg/sample-prometheus-on-heroku.git

6. Add the Heroku git repo URL as a remote:

   git remote add heroku https://git.heroku.com/shielded-beach-38076.git

7. You will now have two remotes: one for origin (the git repo where you develop) and one for Heroku (that it uses to deploy your app)

8. Push the current repo to Heroku remote:

   git push heroku master

9. That's it, you've now got a running Prometheus that is deployed to Heroku! Open the app from UI or from CLI using heroku open.
