SNMP OID for ZPoolHealthType

[unixsamurai]

I am running FreeNAS-11.2-U5 and am wanting to poll FreeNAS's SNMP for ZPoolHealthType, using Nagios

The MIB shows:
::= { enterprises 50536 }

ZPoolHealthType ::= TEXTUAL-CONVENTION
STATUS current
DESCRIPTION
""
SYNTAX INTEGER {
online(0),
degraded(1),
faulted(2),
offline(3),
unavail(4),
removed(5)
}

I think I have it narrowed down to one of 3 OIDs
SNMPv2-SMI::enterprises.50536.1.2.1.1.5.2 = INTEGER: 0
.1.3.6.1.4.1.50536.1.2.1.1.5.2

SNMPv2-SMI::enterprises.50536.1.1.1.1.7.1 = INTEGER: 0
.1.3.6.1.4.1.50536.1.1.1.1.7.1

SNMPv2-SMI::enterprises.50536.1.1.1.1.7.2 = INTEGER: 0
.1.3.6.1.4.1.50536.1.1.1.1.7.2

Can anyone tell me, if I am close, or if it's one of those 3?

EDIT: If I wasn't syncing a ton of data to FreeNAS, I'd take the pool offline and query the OIDs again to see which one went to "3" (offline).

Were you able to figure out the correct MIB?

Not yet. I am confident it's one of those 3 listed OIDs, but haven't been able to test quite yet. Hoping I can test it this weekend.

I tested this. I was able to determine that this is the OID for the zpool health.

SNMPv2-SMI::enterprises.50536.1.1.1.1.7.2
.1.3.6.1.4.1.50536.1.1.1.1.7.2

This makes me think that SNMPv2-SMI::enterprises.50536.1.1.1.1.7.1 (or .1.3.6.1.4.1.50536.1.1.1.1.7.1) is likely the boot pool health (untested, but logical).

I wrote up the entire process of investigation, if anyone needs more info: https://www.unixsamurai.com/freenas-snmp-oid-for-zpool-health/
