Health endpoint added by default in Rails 7.1

A newly generated Rails 7.1 app will now add an endpoint to your routes file to act as a heartbeat. You can point to many services or monitoring tools to check for downtime.

get "up" => "rails/health#show", as: :rails_health_check

However, this is just an indicator of the application running. If you want to do anything more advanced, like checking if the database is up... feel free to write your own. Ultimately, this is a great addition and will work in most situations.
