Running Node Exporter as a service

For production use, it's recommended to run Node Exporter as a system service. If you're using a system with systemd, you can follow these steps to run Node Exporter as a service:

  1. Create a systemd service file for Node Exporter: Open a new service file for Node Exporter with a command like:

    sudo nano /etc/systemd/system/node_exporter.service

    Then, add the following contents to the file:

    [Unit]
Description=Node Exporter
Requires=node_exporter.socket

[Service]
User=node_exporter
EnvironmentFile=/etc/sysconfig/node_exporter
ExecStart=/usr/sbin/node_exporter --web.systemd-socket $OPTIONS

[Install]
WantedBy=multi-user.target

    Save and close the file when you're done.

  2. Reload systemd: After you've created the service file, tell systemd to reload its configuration with:

    sudo systemctl daemon-reload

  3. Start Node Exporter: Start the Node Exporter service with:

    sudo systemctl start node_exporter

  4. Enable Node Exporter on boot: If you want Node Exporter to start automatically when your system boots, use:

    sudo systemctl enable node_exporter

You can check the status of the Node Exporter service at any time with the following command:

sudo systemctl status node_exporter

This should show that the service is active (running). This starts Node Exporter on its default port, 9100. You can check if Node Exporter is running by visiting http://localhost:9100/metrics in your web browser. This page displays the raw metrics that Node Exporter exposes to Prometheus.
