Node Exporter on Grafana

Configuration guide — Visualize Node Exporter metrics on Grafana dashboard

Introduction

In this article we’ll look at how to view metrics from Node Exporter on Grafana dashboard.

Prerequisites

• Machines that expose their system metrics using Node Exporter
• Prometheus installed and configured to scrape Node Exporter exposed metrics
• Grafana installed

You’re missing one of the prerequisites? Check my special monitoring list and you’ll find a tutorial on how to do it.

Before you start

In my case, I have a RHEL8 machine at my disposal. If you’re using Ubuntu, it won’t be much different, but you may need to adjust some commands.

Configuration

Go to Menu > Connections > Data sources (he path may be different depending on the version of Grafana you are using)

Press + Add new data source

Select Prometheus as Time series databases

Choose a name and enter your Prometheus address

Press Save & test

Now go to Menu > Dashboards

Press New > Import

Enter 1860, the dashboard ID for Node Exporter metrics, then press load

Choose prometheus as data source, then press Import

Result

You now have a nice dashboard listing all the system metrics for the monitored machines
