How to use this page

The tables below condense what you typed during seven modules, with the exact names of the kit (http_requetes_total, job="api", labels service, conteneur, niveau, code) and, for each example, the real result obtained on the course machine: what varies from one machine to another (throughputs, durations, identifiers) is flagged as such, but the order of magnitude and the shape of the result are those you will see. The second half of the page maps what the lab deliberately left aside: distributed traces, OpenTelemetry, exemplars, long retention, Kubernetes. Each topic says honestly what the lab is missing and what would need to be added.

Preview — the rest of the lesson is for enrolled readers.
