SNMP: No such object available on this agent at this OID

I am trying to monitor the state of a UPS (NetVision), using the provided mib file. So, upsBatteryStatus should be .1.3.6.1.2.1.33.1.2.1.0

snmpwalk -c COMMUNITY -v1 192.168.1.10 .1.3.6.1.2.1.33.1.2.1.0iso.3.6.1.2.1.33.1.2.1.0 = INTEGER: 2

And here comes the tricky part:

snmptranslate -Of SOCOMECUPS-MIB::upsBatteryStatus.iso.org.dod.internet.private.enterprises.socomecSicon.software.network.netvision.upsObjects.upsBattery.upsBatteryStatus

snmptranslate -On SOCOMECUPS-MIB::upsBatteryStatus.1.3.6.1.4.1.4555.1.1.1.1.2.1 Its different from .1.3.6.1.2.1.33.1.2.1.0 , and it doesnt respond with a value.

check_snmp -H 192.168.1.10 -C COMMUNITY -o upsBatteryStatus -w 1 -c @3:7 -m /var/lib/mibs/ietf/NetVision-nv6-unix.mib -l "Battery Status: "

External command error: Error in packet Reason: (noSuchName) There is no such variable name in this MIB. Failed object: SOCOMECUPS-MIB::upsBatteryStatus

Any ideas why it isnt recongnizes as upsBatteryStatus ?

There seem to be 2 objects with the object name upsBatteryStatus in 2 different MIBs: and . That explains the different OIDs. Nothing wrong with that. The OID is the true identifier of an object, the name is just for us humans.

As far as the error, I don't know what check_snmp does, so cannot say anything about that. But, have you tried this command?

snmpwalk -c COMMUNITY -v1 192.168.1.10 .1.3.6.1.4.1.4555.1.1.1.1.2.1

Helpful commands:

snmptranslate -Tp -m /usr/share/mibs/ietf/NetVision-nv6-unix.mib

and:

"upsBatteryStatus" "1.3.6.1.2.1.33.1.2.1"

 | | | | | +--upsBattery(2) | | | | | | | +-- -R-- EnumVal upsBatteryStatus(1) | | | | Values: unknown(1), batteryNormal(2), batteryLow(3), batteryDepleted(4)

Nagios check_snmp command that reported the correct value is:

/usr/local/nagios/libexec/check_snmp -H 192.168.1.10 -C COMMUNITY -m /var/lib/mibs/ietf/NetVision-nv6-unix.mib -o upsBatteryStatus -w @0:1 -c @3:7 -l "Battery Status: "
SNMP OK - Battery Status: 2 | 'Battery Status: '=2;1;7; 

Thank you for help.
