## Deployment

```shell
sb install node-exporter
```

## Usage

Node Exporter is installed directly on the host at `/opt/node_exporter/node_exporter` and runs as a systemd service. It exposes system metrics on port 9100 for Prometheus to scrape. Manage with `systemctl status/restart node_exporter`.

Note: Metrics are not password-protected by default. Consider firewall rules if exposing port 9100 externally.
