Problem SNMP UNKNOWN

[sofiane]

Hello, I have a problem with snmp services. Indeed, each of them are "unknown" and i have an "error in packet"



I think I have well configured, I don't understand what is the real problem.

I installed packets "nagios-snmp-plugins" "nagios-plugins" "snmpd" "snmp"

I provide you my "nagios.cfg", "localhost.cfg", "commands.cfg", "templates.cfg"

nagios.tar.gz

Thanks for your help

To satisfy my own selfish curiosity, is there a particular reason you're using SNMP to gather metrics from the local machine?

"Error in packet" is a message generated by the snmpd agent. Generally it means the OIDs you're querying are unavailable. I would double-check the scope that the "public" community has within your snmpd configuration as well as making sure that the UCD-SNMP-MIBs module is correctly exposed by the snmpd agent.

I use snmp in localhost services, just for a snmp test (to see if it works).

Why ? I shouldn't do it ?

SNMP is nice, so you could use it everywhere (that's my opinion)

But could you try the following command on the command line:

Code: Select all

snmpwalk -v2c -c public 127.0.0.1

And see if that works...

If that works, you could also try the following commands:

Code: Select all

snmpget -v2c -c public 127.0.0.1 sysUpTime.0

and

Code: Select all

snmpget -v2c -c public 127.0.0.1 .1.3.6.1.2.1.1.3.0

The last one tells you if there might be a problem with the MIB files. It's actually the same command, but with the full OID instead of using the MIB files.

I tried your commands.

There seems to be a problem with your MIB files.

Did you install net-snmp-libs package?
That's where the MIB files are in.

In Centos / Fedora the MIB are normally installed in:

Code: Select all

/usr/share/snmp/mibs/

[sofiane]

No, I just installed "nagios-snmp-plugins" "nagios-plugins" "snmpd" "snmp".

Edit : I installed it

[kyang]

Sounds good,

Is it still having the same SNMP unknown error once you installed?

[sofiane]

Yes, with an other

[rhassing]

Is there a difference when you run the commands I mentioned before?
