In their own words
Prometheus Node Exporter
Prometheus Node Exporter exposes hardware and operating-system metrics from *NIX kernels for Prometheus. Written in Go, it uses pluggable collectors, with default coverage for CPU, disk I/O, filesystem, memory, and network metrics where the operating system supports them. Command-line flags enable or disable collectors, and some collectors accept include or exclude filters. The exporter listens on HTTP port 9100 by default. Documentation covers Linux distribution packages, an Ansible community role, and container deployment. Containerized monitoring requires host namespace access and suitable mounts; some systems also need an extra capability for the timex collector. Certain collectors are off by default because they can have high cardinality, take longer, or consume host resources. The project is Apache 2 licensed and free, with no paid plans listed. Windows users are directed to Windows Exporter.
