node_exporter

 prometheus.io/

Prometheus exporter for hardware and OS metrics exposed by *NIX kernels, written in Go with pluggable metric collectors.

The Windows exporter is recommended for Windows users. To expose NVIDIA GPU metrics, prometheus-dcgm can be used.

Installation and Usage

If you are new to Prometheus and node_exporter there is a simple step-by-step guide.

The node_exporter listens on HTTP port 9100 by default. See the --help output for more options.

Ansible

For automated installs with Ansible, there is the Prometheus Community role.

NOTE: While the Prometheus Node Exporter is for *nix systems, there is the Windows exporter for Windows that serves an analogous purpose.

Installing and running the Node Exporter

The Prometheus Node Exporter is a single static binary that you can install via tarball. Once you've downloaded it from the Prometheus downloads page extract it, and run it:

# NOTE: Replace the URL with one from the above mentioned "downloads" page.
# <VERSION>, <OS>, and <ARCH> are placeholders.
wget https://github.com/prometheus/node_exporter/releases/download/v<VERSION>/node_exporter-<VERSION>.<OS>-<ARCH>.tar.gz
tar xvfz node_exporter-*.*-amd64.tar.gz
cd node_exporter-*.*-amd64
./node_exporter

You should see output like this indicating that the Node Exporter is now running and exposing metrics on port 9100.
