I am working with snmp for the first time and am having problems, and know that it is probably the result of lack of general knowledge of snmp and how to use Nagios to check snmp. I can't seem to get mibs to work correctly, when I use Ireasoning mib browser I get the results that I expect but when when I use the check_snmp I think I am missing something.

goal: have it list the voltage:
this is the oid:psbatteryvoltage.0,.1.3.6.1.4.1.6302.2.1.2.5.1.0

I am loading mibs.
Here are the results I am getting:
command:/usr/local/nagios/libexec/check_snmp -H host -o psbatteryvoltage -C public -P 2c -m all
result:SNMP OK - Such Instance currently exists at this OID |
command:/usr/local/nagios/libexec/check_snmp -H host -o psbatteryvoltage.0 -C public -P 2c -m all

What is the output from:

Code: Select all

snmpwalk -v 2c -c public host .1.3.6.1.4.1

[rockisland]

I am pretty sure that it is not reading my mibs for some reason. here is what you asked for:

[ruffsense]

its reading it:

SNMPv2-SMI::enterprises.6302.2.1.2.5.1.0 = INTEGER: 54926

[avandemore]

As @ruffsense cites, it does appear to be reading the value.

I'm not sure I understand your question, can you rephrase it?

[rockisland]

I guess I would expect it to return a value using: psbatteryvoltage.0
I guess it doesn't do that, you have to input the actual oid.

[rkennedy]

You may need the MIB if you're looking for the full resolver.

@rockisland - did you have any further questions?

[rockisland]

so that is my problem, I have added the right mib into nagios and it does not look like it works.

when I run this command
:/usr/local/nagios/libexec/check_snmp -H host -o psbatteryvoltage.0 -C public -P 2c -m all
I get
result:External command error: MIB search path: /home/myhome/.snmp/mibs:/usr/share/snmp/mibs
Cannot find module (Q-BRIDGE-MIB): At line 23 in /usr/share/snmp/mibs/f10-openFlow.mib
Did not find 'VlanId' in module #-1 (/usr/share/snmp/mibs/f10-openFlow.mib)
Cannot find module (Q-BRIDGE-MIB): At line 17 in /usr/share/snmp/mibs/f10-fip-snooping.mib

psbatteryvoltage.0: Unknown Object Identifier (Sub-id not found: (top) -> psbatteryvoltage)

when I use the oid like this:
/usr/local/nagios/libexec/check_snmp -H host -o .1.3.6.1.4.1.6302.2.1.2.5.1.0 -C public -P 2c

It works and gives me this:
SNMP OK - 54571 | iso.3.6.1.4.1.6302.2.1.2.5.1.0=54571

this tells me that the mibs are not loaded properly, either the permissions are off or something. unfortunately I haven't had a lot of time to dig into it.

[ruffsense]

Maybe it is case-sentitive psBatteryVoltage.0

[rockisland]

unfortunately not I tried it both ways.
