## What it is
Node exporter is the official Prometheus exporter that exposes hardware and OS metrics from *NIX kernels via an HTTP endpoint on port 9100. It is written in Go with pluggable metric collectors covering CPU, memory, disk, filesystem, and network statistics.

## Use cases
- monitor linux server cpu and memory usage with prometheus
- collect disk and filesystem metrics from hosts
- scrape host metrics into prometheus for alerting
- monitor system metrics across a fleet of servers
- export procfs and sysfs stats as prometheus metrics
- run node exporter in docker to monitor the host

## When to choose
- you need standard host-level metrics for Prometheus on Linux, macOS, or BSD
- you want the official, widely deployed exporter with pluggable collectors
- you are building Kubernetes or bare-metal monitoring with Prometheus

## When to avoid
- you need Windows host metrics (use windows_exporter instead)
- you need NVIDIA GPU metrics (use dcgm-exporter instead)
- you want application-level instrumentation rather than OS metrics

## Facets
- artifact type: service
- maturity: stable
- function: monitoring
- domain: monitoring, self-hosted
- platform: bsd, self-hosted, go
- tags: prometheus-exporter, system-metrics, host-metrics, procfs, observability, devops, linux, macos, docker
