history

Project history and usage

Nagios Plugins is the official plugin collection for the Nagios monitoring architecture: checks such as `check_http`, `check_disk`, `check_ping`, `check_ssh`, `check_load`, and many more. Its history is tied directly to Nagios itself and to the design choice that monitoring checks are external executables with standardized output, thresholds, performance data, and return codes.

Project history

Nagios traces its origin to Ethan Galstad's 1996 MS-DOS paging tool and the 1999 open-source NetSaint release. The Nagios history page says plugins that were originally distributed with NetSaint were soon spun off as a separate NetSaint Plugins project; in 2002 NetSaint was renamed Nagios and NetSaint Plugins development moved to the Nagios Plugins project. The current GitHub repository was created on January 16, 2014, but the codebase and plugin convention are much older.

Adoption history

Nagios Plugins became important because Nagios delegated resource-specific checks to plugins, allowing the core scheduler to monitor almost anything that could be automated. Official docs list network services, system resources, Unix/Linux, Windows and NetWare servers, routers, switches, and community plugins as part of the ecosystem. Homebrew reported only 451 installs over 365 days on July 1, 2026, but that understates adoption because Nagios deployments usually install plugins through Linux distributions, source packages, monitoring appliances, or bundled Nagios stacks.

How it is used

Administrators call plugins directly while testing and then wire the same command into Nagios service definitions. Each plugin prints a short status line to stdout and exits 0 for OK, 1 for Warning, 2 for Critical, or 3 for Unknown. The shared options pattern matters in day-to-day use: `-H` for host, `-w` and `-c` for thresholds, `-t` for timeout, `-v` for verbosity, and `--help` or `--usage` for plugin-specific syntax. Performance data after `|` feeds graphing and long-term metrics.

Why package nerds care

The package is a foundational example of a stable CLI plugin ABI. The individual checks are ordinary executables, but the exit-code and output contract let Nagios, Icinga-style systems, wrappers, and custom scripts compose checks written in C, shell, Perl, Python, or anything else. For package maintainers, it is also a bundle package: installing one formula drops a fleet of `check_*` tools into Homebrew's sbin.

Timeline

  • 1996: Ethan Galstad creates the early paging/checking tool that becomes Nagios's architectural seed.
  • 1999: NetSaint is released as open source and the plugin code is soon spun out as a separate project.
  • 2002: NetSaint is renamed Nagios and NetSaint Plugins development moves to Nagios Plugins.
  • 2014-01-16: current GitHub repository created.
  • 2026-03-31: Nagios Plugins 2.5 released.
  • 2026-07-01: Homebrew API reported 451 installs over 365 days.
