I was working on an install script for Nagios (Working through the bugs) when I found Check_MK's install script. See http://mathias-kettner.de/check_mk

Anyway its a much cleaner & tested script that works great and includes Check_MK

Check_mk adopts a new a approach for collecting data from operating systems and network components. It obsoletes NRPE, check_by_ssh, NSClient and check_snmp. It has many benefits, the most important of which are:

• Significant reduction of CPU usage on the Nagios host.
• Automatic inventory of items to be checked on hosts.

The larger your Nagios installation is, the more important get these points. In fact check_mk enables you to implement a monitoring environment exceeding 20.000 checks/min on the first hand.

Install Procedure

Download and install Debian 5 Net install:

http://cdimage.debian.org/debian-cd/5.0.5/i386/iso-cd/debian-505-i386-netinst...

Install as normal,

Login as root

#> mkdir nagios

#> wget http://mathias-kettner.de/download/install_nagios-1.1.7i1.sh

#> chmod 777 install_nagios-1.1.7i1.sh

#> ./install_nagios-1.1.7i1.sh

Go through the prompts and thats it, Nagios + Nagvis + Check_MK installed and ready to configure
