Monitoring via SNMP

I have been searching, hashing and working on trying to get monitoring via SNMP for my LTM 1600 boxes. I understand SNMP but there is something that I"m missing I presume.

 

 

I was able to load a MIB Browser and formulate the OID for CPUs (OIDs: .1.3.6.1.4.1.3375.2.1.7.5.2.1.11.1.48.1,.1.3.6.1.4.1.3375.2.1.7.5.2.1.11.1.48.2). I used the same formula to work on getting other metrics and I have not been able to. I can pull data via MIB Browser and running an snmpwalk. But I can not get the same check as CPU to pull data.

 

 

Using the snmpwalk from OID: .1.3.6.1.4.1.3375.2.1.1.2 (found in forums), I get a long list. Pulling out one of those, I can get a data response.

 

$ snmpwalk -v 2c -c xxxxxx host SNMPv2-SMI::enterprises.3375.2.1.1.2.21.16.0

 

SNMPv2-SMI::enterprises.3375.2.1.1.2.21.16.0 = Counter64: 2

 

 

I convert it to it's full OID, and it comes back.

 

$ snmpwalk -v 2c -c xxxxxx host .1.3.6.1.4.1.3375.2.1.1.2.21.16.0

 

SNMPv2-SMI::enterprises.3375.2.1.1.2.21.16.0 = Counter64: 2

 

 

But I then turn that into a host check, I get an error.

 

$ ./check_snmp -v -H host -C xxxxxx -o .1.3.6.1.4.1.3375.2.1.1.2.21.16.0

 

/usr/bin/snmpget -t 1 -r 5 -m '' -v 1 [authpriv] idcbip01.host.com:161 .1.3.6.1.4.1.3375.2.1.1.2.21.16.0

 

External command error: Error in packet

 

Reason: (noSuchName) There is no such variable name in this MIB.

 

Failed object: iso.3.6.1.4.1.3375.2.1.1.2.21.16.0

 

 

What am I missing? Both the MIB Browser and the snmpwalk will return data but the same in snmpget wont.
