Nagios ( /ˈnɑːɡiːoʊs/) is a popular open source computer system and network monitoring software application. It watches hosts and services, alerting users when things go wrong and again when they get better.
Nagios, originally created under the name NetSaint, was written and is currently maintained by Ethan Galstad, along with a group of developers actively maintaining both official and unofficial plugins. N.A.G.I.O.S. is a recursive acronym: "Nagios Ain't Gonna Insist On Sainthood",[3] "Sainthood" being a reference to the original name NetSaint, which was changed in response to a legal challenge by owners of a similar trademark.[4] "Agios" is also Greek for 'saint'.
Nagios was originally designed to run under Linux, but also runs well 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.
In a 2006 survey among the nmap-hackers mailing list, 3243 people responded when asked for their favorite network security tools. Nagios came in 67th overall and 5th of the traffic monitoring tools. Nmap itself was excluded from the list. Update: The 2011 list has been released and Nagios is listed at #69. [5]

Nagios Remote Plugin Executor (NRPE) is a Nagios agent that allows remote systems monitoring using scripts that are hosted on the remote systems. It allows for monitoring resources such as disk usage, system load or number of users currently logged in. Nagios periodically polls the agent on the remote system using the check_nrpe
