Adding SNMP MIBs

[jterhune]

I'm about at the end of my rope here, so I figured it was time to ask for help.

I'm trying to get up SNMP monitoring of our Liebert Nfinity UPS.

I started by following section 19.6 of the manual.

On step 2, I discovered that the MIBs for this were not installed. The UPS uses UPS-MIB, from RFC1628. I found instructions on the net-snmp wiki on adding MIBs.

UPS-MIB.txt has been added to the mibs directory and is loaded, but is throwing errors.

"snmptranslate -IR -On upsOutputSource" works with errors:

No log handling enabled - turning on stderr logging
Unlinked OID in UPS-MIB: upsMIB ::= { mib-2 33 }
Undefined identifier: mib-2 near line 13 of /usr/share/snmp/mibs/UPS-MIB.txt
.1.3.6.1.2.1.33.1.4.1

Here is the tail of snmpget -Dparse-mibs -v 1 -c LiebertEM x.x.x.x upsBatteryStatus:

parse-mibs: Parsing MIB: 16 UPS-MIB

Undefined identifier: mib-2 near line 13 of /usr/share/snmp/mibs/UPS-MIB.txt
Error in packet
Reason: (noSuchName) There is no such variable name in this MIB.
Failed object: UPS-MIB::upsBatteryStatus

I thought maybe this wouldn't be a big deal if I just used the OID in zabbix. No dice:

Unlinked OID in UPS-MIB: upsMIB ::= { mib-2 33 }
Undefined identifier: mib-2 near line 13 of /usr/share/snmp/mibs/UPS-MIB.txt
   973:20110324:130237.541 server #3 started [Poller. SNMP:YES]

From what I can tell, this means UPS-MIB is referencing something that isn't imported properly? Something to do with mib-2?

Line 13 of UPS-MIB starts with:

Any help fixing this would be greatly appreciated. My google-fu has failed me.

The single relevant result I found was in Japanese, but Google translate was successful.

Changing

OBJECT-IDENTITY, Counter32, Gauge32, Integer32

to

OBJECT-IDENTITY, Counter32, Gauge32, Integer32, mib-2

in UPS-MIB.txt fixed this.
