sudo apt install prometheus

sudo apt-get install prometheus-node-exporter

now visiting http://localhost:9100/metrics should return metrics

start the prometheus-node-exporter:

sudo systemctl enable prometheus-node-exporter
sudo systemctl start prometheus-node-exporter

for monitoring too the mounted devices (ie. usb): edit /etc/default/prometheus-node-exporter:

ARGS="--collector.filesystem.mount-points-exclude="^/(dev|proc|run|sys|mnt|var/lib/docker/.+)($|/)""

restart the service: sudo systemctl restart prometheus-node-exporter
