[SOLVED] Nagios check_snmp V3 timeout

angel115 · 10-08-2010, 05:17 AM

Hello There,

I'm having a timeout issue with the command check_snmp:
Where I don't understand is that when I tipe the command on the command line it's working fine but not when I put it in the host configuration file.

The following is working fine:

Code:

# ./check_snmp -H IP-TO-CHECK -o ".1.3.6.1.4.1.2.3.51.2.2.10.1.1.1.10.2" -U USER -A PASSWORD -x AES -X PASSWORD_SNMP -L authPriv -P 3 -a MD5 -u W -w 1000 -c 1050
SNMP OK - 859 W | iso.3.6.1.4.1.2.3.51.2.2.10.1.1.1.10.2=859

The same line in the config file:

Code:

define service{
        use                             generic-service         ; Name of service template to use
        host_name                       IP-TO-CHECK-BladeCenter
        service_description             Power Domain 1 Utilization
        check_command                   check_snmp!-o ".1.3.6.1.4.1.2.3.51.2.2.10.1.1.1.10.2" -U USER -A PASSWORD -x AES -X PASSWORD_SNMP -L authPriv -P 3 -a MD5 -u W -w 1000 -c 1050
        }

Give me this:

Code:

    External command error: Timeout: No Response from IP-TO-CHECK:161.

and if I do specify a timeout value with the "-t" option it give me a timeout critical error.

Any idea/lead?

Have you tried it without the ""?

I think the problem you are having is related to how the command is parsed. I looked through my Nagios configs and I don't use "" anywhere in the command strings.

Try from the command line:

Code:

# ./check_snmp -H IP-TO-CHECK -o .1.3.6.1.4.1.2.3.51.2.2.10.1.1.1.10.2 -U USER -A PASSWORD -x AES -X PASSWORD_SNMP -L authPriv -P 3 -a MD5 -u W -w 1000 -c 1050

and this in your Nagios Config:

Code:

define service{
        use                             generic-service         ; Name of service template to use
        host_name                       IP-TO-CHECK-BladeCenter
        service_description             Power Domain 1 Utilization
        check_command                   check_snmp!-o .1.3.6.1.4.1.2.3.51.2.2.10.1.1.1.10.2 -U USER -A PASSWORD -x AES -X PASSWORD_SNMP -L authPriv -P 3 -a MD5 -u W -w 1000 -c 1050
        }

Yes, I did and it, but just re-test it again, and it is the same.

Code:

External command error: Timeout: No Response from IP-TO-CHECK:161.

One thing that I don't understand is that it's working fine from command line.
I do monitor over 1000 services and hosts on our network and everything works.

Only the three SNMPV3 check on this host doesn't.

The other thing that comes to mind may be your User / Password. Do they have any special characters that could be intercepted rather than passed in some way (a $ for example).

If it is all related to one host, it has to be something common to those entries. Look for special characters in the Username and password, that is the only other thing I can think of.

Yes, I just figured out.

I've got a "!" in one password.

after testing wrapping the password with single or double quote give me a "Null" result, so I change my password and remove the exclamation mark character.

Doing so solved my issue.

Thanks you for helping
