Uptime and monitoring

RailsFast comes preconfigured with the allgood gem for health checks / smoke tests.

You can see all your current health checks by navigating to /healthcheck:

By default, we check things like whether the database is up and running, the server has enough disk and memory, etc. You can customize your health checks by editing your config/allgood.rb file. Check the allgood docs to know everything you can add to check the health of your app!

The recommended use of this /healthcheck endpoint is to use it together with an uptime monitoring service like UptimeRobot. In UptimeRobot, you'd just add https://YOURAPP.COM/healthcheck as an URL to monitor every 5 minutes, and whenever any of the checks fail, you'd get a notification, a call, or a text, depending on what you have configured. It's very useful to quickly know if there's anything wrong with your app and fix it before any of your users notice!
