Monitoring ZFS disk usage using SNMP

Hi guys,

Is is possible to monitor disk space usage % via SNMP of a Freenas sever? The current file system is ZFS

We use PRTG for network monitoring and I've been able to successfully setup CPU, Network, Memory and uptime monitors but when PRTG did a detailed discovery of the server nothing to monitor disk space came up?

I think I need to add something to the "Aux" part of the SNMP server setup but I have very limited knowledge of SNMP on BSD.

Any help would be greatly appreciated....
