Nagios, now known as Nagios Core, is a free and open source computer-software application that monitors systems, networks and infrastructure. Nagios 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.
Nagios was originally designed to run under Linux, but it 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 this ebook, we provide a compilation of Nagios tutorials that will help you set up your own monitoring infrastructure. We cover a wide range of topics, from installation and configuration, to plugins and NRPE. With our straightforward tutorials, you will be able to get your own projects up and running in minimum time.
