If you have multiple applications on Heroku and would like to use a single Logentries account for all of them, this is how you do it. Basically, do not use add-ons, and send all drains to your account.

• In your Logentries account, click on Add Log
• Select Manual
• In the form that appears, input the following:
  • Log Name: access.log
  • Select Set: new set named myapp-{environment}, for instance myapp-staging (at least, this is how I like to name my entries)
  • Select the Plain TCP, UDP - logs are sent via syslog option
• Click on Create Log Token

Erlang Release init.d script

If you have packaged your application into a release generated with Rebar, you might want to have the following:

• The release started on system boot.
• The VM monitored and restarted it if it crashes.

Use HEART

HEART is the Heartbeat Monitoring of an Erlang Runtime System. The purpose of the heart port program is to check that the Erlang runtime system it is supervising is still running, so that if the VM crashes or becomes unresponsive, it is restarted.
