OIDs for SNMP Monitoring Disk Space

[connor.johnson]

I have TrueNAS 12.0 and use Auvik to monitor our systems.

Auvik is giving the incorrect value for disk utilization and that means they have the wrong OIDs. I was hoping I could get some help finding the correct OIDs but iXsystems support doesn't know their own product. So I am asking the community if anyone has any idea where I can find the OIDs for Desk space utilization. Thank you!

The Mibs are:
HOST-RESOURCES-MIB::hrStorageAllocationUnits.13
HOST-RESOURCES-MIB::hrStorageSize.13
HOST-RESOURCES-MIB::hrStorageUsed.13

So, clarify this for us. You're a TrueNAS Enterprise customer and they wouldn't give you the OID's?

Or you're a free product "customer" and didn't understand that their support is only for the paid customers?

I am a TrueNAS Enterprise Customer and they don't even know where to get the OIDs. I am a paying customer.

I have a Silver level contract that expires 2026-01-14

I'm not entirely certain what you need. I'm not an SNMP guy; I think it's a terrible protocol, just better than all the even horribler alternatives.

The MIB files over at /usr/local/share/snmp/mibs such as FREENAS-MIB.txt may be a starting point.

You could also try to file a Jira ticket ("Report a Bug") at the top to see if you can prod any of the developers. SNMP is a bit of a niche thing but it looks like they want to support it. That may not always translate into support knowing what SNMP is.

@connor.johnson, @jgreco pointed you to the correct MIB. Most storage MIBs don't understand ZFS. In your case, you want:

.iso.org.dod.internet.private.enterprises.freeNas.zfs.zpool.zpoolTable.zpoolEntry.zpoolAllocationUnits (.1.3.6.1.4.1.50536.1.1.1.1.3)
.iso.org.dod.internet.private.enterprises.freeNas.zfs.zpool.zpoolTable.zpoolEntry.zpoolSize (.1.3.6.1.4.1.50536.1.1.1.1.4)
.iso.org.dod.internet.private.enterprises.freeNas.zfs.zpool.zpoolTable.zpoolEntry.zpoolUsed (.1.3.6.1.4.1.50536.1.1.1.1.5)
