This is a Heroku log drain that connects to a Spark Core device running Sparoku Status to render a visualization of how your dynos are doing.
Start setting up your device following the Sparoku Status instructions.
Once the device is ready deploy your drain:
$ npm install $ cp .env.sample .env
You can then boot the server locally with
foreman start, and make requests immitating the Heroku router, like:
$ curl -d "heroku router dyno=web.1 status=500" -H "Content-Type: application/logplex-1" http://localhost:5000/logs
This should make the first light on the device turn red.
