## Update prometheus config to include node_exporter
Add the following to the prometheus config and then restart prometheus:
```
- job_name: node_exporter
static_configs:
- targets: ['localhost:9100']
```
## Import system dashboard
Since our `prometheus.yml` config already has configuration for node_exporter we can go straight away and import a Grafana dashboard for viewing:
1. Download the most recent dashboard from https://grafana.com/grafana/dashboards/1860-node-exporter-full/
2. Log in to Grafana (http://localhost:3000) using the web interface.
3. Navigate to "Home" > "Dashboards" > Click the drop down menu in the "New" button and select "Import"
