Monitoring Linux Host Metrics with Prometheus | Node Exporter (Setup, Scrape, Query, Grafana)

In this video, I show you how you can use the Prometheus Node Exporter to monitor Linux (or Unix) host metrics. We first download and run the Node Exporter and then we monitor it with Prometheus. Then, we explore some of the available metrics in Prometheus and show how to import an exhaustive Node Exporter dashboard into Grafana.
