## Course summary

**Six things to remember**

| \# | Takeaway                                                                         |
|----|----------------------------------------------------------------------------------|
| 1  | **External collectors work**: Bring your own collectors, let Grafana Cloud store |
| 2  | **Match method to source**: Prometheus → remote write, InfluxDB → exporter, etc. |
| 3  | **OpenTelemetry is universal**: OTLP works for both metrics and logs             |
| 4  | **HTTP API is flexible**: Any HTTP client can send logs                          |
| 5  | **Mimir stores metrics**: Prometheus-compatible, scalable                        |
| 6  | **Loki stores logs**: Query with LogQL, correlate with metrics                   |
