TrueNAS Scale SNMP Monitoring

[dnut]

Hello There,
we have many installations of TrueNAS Core and TrueNAS Scale that we monitor using Zabbix via SNMP.

With TrueNAS Core we can retrieve info about datasets:
we just use this Template and it works out of the box with TrueNAS Core

TrueNAS monitoring and integration with Zabbix

www.zabbix.com

With TrueNAS Scale, however, we are not able to retrieve dataset information.
In TrueNAS Scale, looking at the SNMP specification using snmpwalk, shows there are no infos about datasets, just zpools.

Any idea?

Thank you

Observium display the datasets just fine:



The HOST-RESOURCES-MIB has all the information:

If I'm not mistaken, that's the file system, not the datasets.

How can I populate discovery rules for datasets (for example in Zabbix) using those data?
Yes can be done, maybe using tags, but that's not straightforward like TrueNAS Core SNMP implementations, which list datasets, and relative properties, instead.

A dataset is a file system and a file system is a dataset in ZFS ... you are correct that they are listed by mount point and not by ZFS path, but that's enough for my use case. I don't use Zabbix but Observium, sorry.
