How to verify the rules are loaded?

That's a great question! After you've applied the configuration changes and restarted the Prometheus container, you can verify that the rules are loaded by accessing the Prometheus web interface.

1. Open the Prometheus UI: You should be able to access it in your browser, usually at http://localhost:9090 (if you're using port forwarding or have configured it locally) or via the provided "Access Prometheus" button in your LabEx environment.
2. Navigate to the "Alerts" section: Once in the Prometheus UI, look for the "Alerts" tab or menu item.
3. Check for your rules: If your alert-rules.yml file was loaded correctly, you should see your defined alert rules listed there.

This is the most direct way to confirm that Prometheus has picked up your new rule configuration. Give it a try!
