+## Monitoring
+
+Applying the Prometheus monitoring manifest allows you to observe the device plugin status:
+
+```bash
+kubectl apply -f manifests/cc-device-plugin-pod-monitoring.yaml
+```
+
+You can view the metrics in the [Cloud Monitoring Metrics Explorer](https://console.cloud.google.com/monitoring/metrics-explorer) using PromQL, for example to see CPU usage:
+```promql
+rate(process_cpu_seconds_total[5m])
+```
