Nagios SNMP extra plugins
The general idea of these scripts is to check as many things as possible with snmp : disks, memory, load, interface, running procsses, etc...
The other idea is to select (or exclude) 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 output performance data.
