Nagios /ˈnɑːɡiːoʊs/ is an event monitoring system that offers monitoring and alerting services for servers, switches, applications and services. It alerts users when things go wrong and alerts them a second time when the problem has been resolved.
Ethan Galstad and a group of developers originally wrote Nagios as NetSaint.[3] As of 2015[update], they actively maintain both the official and unofficial plugins. Nagios is a recursive acronym: "Nagios Ain't Gonna Insist On Sainthood"[4] – "sainthood" makes reference to the original name NetSaint, which changed in response to a legal challenge by owners of a similar trademark.[5] "Agios" (or "hagios") also transliterates the Greek word άγιος, which means "saint".
Nagios was originally designed to run under Linux, but it also runs on other Unix variants. It is free software licensed under the terms of the GNU General Public License version 2 as published by the Free Software Foundation.

Nagios – whose name is a recursive acronym ("Nagios Ain't Gonna Insist On Sainthood") ironically refers to the original name NetSaint changed to avoid trademark troubles – is among the most popular open source network management tools and application.

The official meaning is that N.A.G.I.O.S. is a recursive acronym which stands for "Nagios Ain't Gonna Insist On Sainthood".

Although we were able to eventually reach an amicable agreement on my future use of the name "NetSaint", I felt it was prudent to change the name in order to prevent any future mishaps.
