SNMP Modular Input: Why is the custom MIB not loading and displaying "NoSuchObjectError" error?

[ww9rivers]

After installing the latest version of the SNMP Modular Input add-on (1.2.7), I got it to work on reading temperatures from our data center racks.

The AFCO racks use this simple SNMP v1 MIB, which I converted to PySNMP MIB.

Using numerical OIDs (e.g. .1.3.6.1.4.1.29660.2.3.2.0) the module is able to read the temperatures. Now, I am having difficulties trying to configure it to use the MIB. I've tried to set "Object Names List" to these:

• Temperature2,Temperature3
• Temperature2.0,Temperature3.0
• AFCOMFG-TMM-MIB::Temperature2,AFCOMFG-TMM-MIB::Temperature3
• AFCOMFG-TMM-MIB::Temperature2.0,AFCOMFG-TMM-MIB::Temperature3.0

None of those seems to work. The errors I'm getting are:

Is the AFCOMFG-TMM-MIB.py file in the snmp_ta/bin/mibs directory ?

Did you declare this MIB to be applied ?

Did you generate Python files for any other dependent MIB's that are not part of the default SNMP App ? You can view these in snmp_ta/bin/mibs/pysnmp_mibs-0.1.4-py2.7.egg , and also declare these MIBs to be applied

Thank you very much for the response.

Yes. That file is there:

splunk@splunkapp-dev03:/app/splunk/etc/apps/snmp_ta/bin/mibs> ls -l
total 4596
-rw-r--r-- 1 splunk splunk    6532 Nov 28 16:34 AFCOMFG-TMM-MIB.py
drwxr-xr-x 3 splunk splunk    4096 Nov 28 10:40 EGG-INFO

-rw-r--r-- 1 splunk splunk 4669138 Nov 20  2014 pysnmp_mibs-0.1.4-py2.7.egg

And, yes, the MIB is specified in the "Custom MIBs" configuration box. But I don't have another custom MIB, so the AFCOMFG-TMM-MIB is the only one in there. I don't think I must have multiple MIBs in that configuration item but I will try to specify another one in the egg.

Tried with:

Custom MIBs : MIB Names  = AFCOMFG-TMM-MIB,RFC1213-MIB

and

Object Names List = AFCOMFG-TMM-MIB::Temperature2.0,AFCOMFG-TMM-MIB::Temperature3.0

Getting the same error messages.

When I look at https://github.com/ww9rivers/SnmpMibs/blob/master/AFCOMFG-TMM-MIB.mib , I see that it has many other MIB Imports. Not all of these are available by default , so you have to build the python modules for these.
