Build the everyday dashboard with one row per golden signal, add an alert on api ERROR log lines, and trigger it on purpose to watch it fire.

Watching systems every day and during a load test, with Grafana, Alloy, Prometheus and Loki against the Pizza Playground.

Walk through the Alloy config block by block, start Alloy with the right mounts, and check that container metrics and logs reach Prometheus and Loki.

Start Grafana on port 3001, log in, connect the Prometheus and Loki data sources, and check both in Explore.

Start Prometheus in Docker next to the Pizza Playground, give it a small config, and check that it is ready and scraping itself.

The four tools used here (Alloy, Prometheus, Loki, Grafana), what each one does, how data moves between them and what we can see without changing the app.

Send k6 results to Prometheus, put them on one Grafana dashboard next to the server, and read cause and effect during a load test.

The signals a tester cannot see from outside the app, why they matter in a load test, and how to ask the developers for them.
