Health Checks and Application Monitoring

Health checks help operations teams know when something is wrong.

  ## Simple endpoint
  
  ```php
  Route::get('/health', function () {
    return response()->json(['status' => 'ok']);
  });
  ```
  
  ## Typical checks
  - database ping
  - cache connection
  - queue worker alive
  
  Health checks improve reliability.
  
  In the next tutorial, we will analyze logs and errors.
