How to Easy Install Nagios using FAN Tool

FAN stands for Fully Automated Nagios and it is designed as a quick and easy installation of Nagios along with the most used tools in the Nagios community. It is designed as a stand-alone installation based on CentOS 5.9. FAN is available in iso image format and it’s easy to burn on a CD or DVD. A large number of tools are also being distributed, which makes the implementation of an efficient monitoring platform much easier.
