Using Nagios to check the health of FreeNAS arrays

[Solved] Using Nagios to check the health of FreeNAS arrays

I have 2 disk-arrays on my freeNAS8 instance.
The script I have for checking drives is looking for /dev/somedrivename
I can use it to check the root partition, but the arrays one with 5 disks in it and the other with 6 disks are shown by df as only the array name mounted at /mnt/array1 and /mnt/array2
the nagios script cannot fathom this location. None of the array drives are mounted in BSD, but only in FreeNAS.

Is there a way to set FreeNAS itself to send me an alert when or if the drive arrays fill up? or are the arrays accessible through the system otherwise?

Can't you have it tell you the amount of consumed space for the particular mountpoint instead? If not, I would write a plugin (if you can't find one on the nagios plugin exchange) that does a df of the volume you wish to monitor and returns the numbers. Shouldn't be too difficult.

Why don't you just use the nightly reports that are built in to FreeNAS?? I get an email every night at 3am with disk usage and more....

louisk:
I edited the plugin to call the mount point and it was very simple. Works like magic!

protosd:
I guess I didn't realize that FreeNAS did that stuff, and I was in a contextual frame of having my monitoring software monitor the network.

Thanks to you both.
