Grafana Guide for the Monitoring Stack¶

Grafana provides the dashboards and log views for the monitoring lab.

Important Files¶

• grafana/provisioning/datasources/datasources.yml
• grafana/provisioning/dashboards/dashboards.yml
• grafana/dashboards/advanced-monitoring-dashboard.json

What Happens Automatically¶

Grafana is provisioned on startup, so you do not need to create data sources and dashboards by hand every time.

That usually gives you:

• A Prometheus data source
• A Loki data source
• A ready-made dashboard for the stack

Why Provisioning Matters¶

• Keeps dashboards reproducible
• Prevents manual drift
• Makes reviews easier because changes live in Git

What to Validate¶

• Prometheus data source is healthy
• Loki data source is healthy
• Dashboards load without broken panels
• Panels show useful host, container, and probe metrics

Good Dashboard Areas¶

• CPU, memory, disk, and network
• Container resource trends
• Prometheus target health
• Probe success rate
• Recent logs from Loki
• Alert summary

Quick Check¶

docker compose logs -f grafana
curl http://localhost:3000/api/health
