Project history and usage
NRPE is the Nagios Remote Plugin Executor: a daemon and companion check plugin used to run Nagios-compatible checks on remote hosts and return plugin output/status to a Nagios server. The upstream README frames it as a way to execute Nagios plugins remotely as transparently as possible.
Project history
NRPE predates its GitHub repository; Nagios announced on May 8, 2014 that NRPE, Nagios Core, and NDOUtils moved from SourceForge to GitHub to make community contributions easier. The GitHub repository was created on January 21, 2014, matching that migration period.
Adoption history
NRPE became one of the classic ways to extend Nagios monitoring from network-visible checks into host-local checks such as disk, process, load, and custom scripts. Even where newer agents such as NCPA or direct exporters are used, NRPE remains packaged by multiple Linux distributions and Homebrew because many Nagios/Icinga-style deployments still understand `check_nrpe`.
How it is used
Operators install the NRPE daemon on monitored hosts, configure allowed monitoring servers and named commands in `nrpe.cfg`, then run `check_nrpe` from the monitoring server to request those commands. The model deliberately separates the remote agent (`nrpe`) from the Nagios-side plugin (`check_nrpe`).
Why package nerds care
NRPE is historically important monitoring plumbing: small, old, and security-sensitive. Its changelog shows why packagers care about versioning, because the 4.0.0 release on January 13, 2019 included security fixes affecting both daemon and plugin while preserving interoperability with older versions.
