-# orthanc-monitoring
-First trial for monitoring
+# Orthanc-monitoring
+
+## Summary
+Here is only a basic Orthanc with a Postgres.
+
+But these 2 services, as well as the host system and the containers, are monitored thanks to Prometheus.
+Grafana is also there to show the metrics.
+
+## How it works
+
+### Prometheus
+
+Prometheus will collect the metrics from these sources:
+- Orthanc ([link to official doc](https://book.orthanc-server.com/users/advanced-rest.html#instrumentation-with-prometheus))
+- Node-exporter (allow to get the metrics from the system: CPU, RAM, disk space,...)
+- Postgres (thanks to the exporter)
+- CAdvisor (allow to get the metrics from the containers)
+
+### Grafana
+
+There is a predefined dashboard with all the metrics listed above.
+
+## Misc
+- There is a volume for the dashboard (Grafana container) so, if an update (with a new version of the dashboard) has to be made, the volume has to be deleted (otherwise, the dashboard will remain as it was)
