Deploying the Node Exporter To begin collecting system-level metrics, deploy the Node Exporter container. This requires mounting host paths to allow the exporter to read proc and sys filesystem statistics. docker run -d \ --name node-metrics \ --restart unless-stopped \ -p 9100:9100 \ -v "/proc:/host/proc:ro" \ -v "/sys:/host/sys:ro" ...
