Connect Grafana to Prometheus

Grafana has zero datasources configured. Provision a Prometheus datasource via YAML so real queries work.

A intermediate Prometheus & Grafana challenge worth 10 points. Solve it hands-on in a real Prometheus & Grafana environment in your browser - no local setup, no fake shells.

The Challenge

Scenario: Grafana is up and Prometheus has real data, but Grafana has no idea Prometheus exists - there isn't a single datasource configured, provisioned or otherwise.

Your tasks:

1. Find Grafana's datasource provisioning directory.
2. Write a datasource provisioning YAML file declaring a Prometheus datasource pointed at the real running Prometheus server.
3. Restart Grafana and confirm the datasource can actually query live metrics (not just that it appears in the list).

Commands to learn: Grafana provisioning YAML (apiVersion, datasources, access: proxy), curl against Grafana's API.

Run check when done.
