Monitor ZFS filesystem using SNMP service

Hi all

I’m using zabbix to monitor my pfsense using SNMP, and it works beautifully. I’m using the official Zabbix SNMP template for pfSense as I dont like to have the zabbix agent running on my fw.

It discovers all the needed hardware, interfaces and what not - and monitors it all without issue (If you adapt the macro’s to your interface drivername)

I have one little snag though. It does not discover/monitor the ZFS filesystem correctly. Seems the template is made for pfsense 2.5 without ZFS.

I can’t seem to figure a way to have Zabbix discover the ZFS filesystem correctly and monitor its space usage.

Does the built in SNMP service expose the ZFS filesystem, and does it expose any metrics on its usage? I’m thinking I need to modify the template to discover the correct filesystem key name, but what is that name?
