Background
The Prometheus Node Exporter is an essential component for monitoring Linux systems. It collects hardware and operating system metrics, such as CPU usage, memory, disk, and network statistics. By bridging between Prometheus and the kernel, it enables effective monitoring and troubleshooting. Whether you’re tracking resource utilization or setting up alerts, the Node Exporter provides valuable insights into your infrastructure’s health and performance.
How to Install Prometheus Node Exporter
First update your Raspberry
sudo apt-get update && sudo apt-get upgrade
Following this you need to download Prometheus Node Exporter
sudo wget -O node-exporter.tar.gz https://github.com/prometheus/node_exporter/releases/download/v1.7.0/node_exporter-1.7.0.linux-armv7.tar.gz
Next step is to un-tar by the below command
sudo tar -xvf node-exporter.tar.gz
In the next step (you maybe select a different way) I have moved the files into the /opt
sudo mkdir /opt/prometheus_node_exporter-1.7.0.linux-armv7
Move the files towards the freshly created target directory in /opt
mv * /opt/prometheus_node_exporter-1.7.0.linux-armv7/
Obviously we like the service to be started automatically. Therefore we create first a service:
sudo vi /etc/systemd/system/nodeexporter.service
Within this file I put the following content:
[Unit] Description=Prometheus Node Exporter After=network-online.target [Service] User=pi Restart=on-failure ExecStart=/opt/prometheus_node_exporter-1.7.0.linux-armv7/node_exporter [Install] WantedBy=multi-user.target
Once done. We enable the new service:
sudo systemctl enable nodeexporter
Next, we start the service:
sudo systemctl enable nodeexporter
Finally, we test if the service is running:
sudo systemctl status nodeexporter
Test whether you can access it via your browser <YOUR IP Address:9100>. This should look like the below:
