The general idea of these scripts is to check as many things as possible with SNMP: disks, memory, load, network interfaces, running processes, etc... The other idea is to select disks, interfaces, process using regular expressions: - it is possible to test more than one disk/int/process in one Nagios check (ex.: eth* instead of eth0,eth1,eth2,...) - you only have to provide a unique part of the name to select a disk/int/process (ex. : "C:" instead of "C:\ Label: Serial Number xxxxxxx" makes it easy to use on multiple Windows hosts). Most of these scripts can make performance outputs. WWW: http://nagios.manubulon.com/
