After a couple of days of looking around and investigating on this i'm getting a little bit tired. I think i literally tried everything that i could find on the exchange that has something to do with snmp qnap disk spaces etc..
The thing that i found usefull was this topic: http://support.nagios.com/forum/viewtop ... =7&t=29213
Which, got me on track with some working IOD numbers for Free Space and Total Space.
Now i had the great idea to combine those two together to get what i want, in theory "This is the total space, minus the free space equals the used space" and then i would get the option to use warning and critical like all other scripts!
But yeah my ideas were as usually out of my capabilities.
Can somebody help me with this?
P.S. the most important thing is that it will be able to check seperate volumes on the QNAP.
Kind regards,
Farid
