This is planning to have the above open source solution on monitoring windows and linux servers. How should I setup? Which Linux Distro is the best for Nagios? and where can I get all those useful documents?

Firstly you need to set out and plan what servers you wish to monitor and the type of monitoring you will use. Eg: Server name, types of information you need like Disk usage, Ram usage, CPU and so on.

I installed Nagios on a Fedora 15 install and found it quite compatible with little trouble. Below is a guid on a quick step installation. At the end of the doco is methods for monitors all types of servers and so on.

Hope this is helpful.

The Nagios monitoring system consists of a server, which controls all the monitors and server lists and provides the web interface for visualisation, and a client, which is installed in the servers that are to be monitored. Due to this characteristic, there are two different installation processes. The client installation, which is simpler, and the server installation, which consists also in configuring an Apache web server for the visualisation interface. You could have Centos, fedora, RHEL or Ubuntu as a based OS.
