Prometheus : Install an External Node Exporter
1Documentation : https://sbcode.net/prometheus/prometheus-node-exporter/
Now we will install an external Prometheus Node Exporter on a different server.
# apt install prometheus-node-exporter
Node exporter will now be running on http://[your domain or ip]:9100/metrics
You can now block port 9100 externally, but leave it open internally for localhost.
And optionally, you can also allow a specific ip address or domain on the internet to access the port.
Add the new scrape config for the new node exporter to the Prometheus configuration yml on your Prometheus server.
Scroll down to the bottom and add a new scrape target to the existing node job.
If you want to add ssl to the external node exporter you can also use an nginx reverse proxy and add a path specific for the node exporter.
