Nagios Support Forum

Hi Experts,

I have run the snmp walk monitoring wizard to configure the firewalls using SNMP v3, we are able to list down all the port and gave the warning and critical but with the service check we have received the below output.

Usage:check_snmp -H <ip_address> -o <OID> [-w warn_range] [-c crit_range]
[-C community] [-s string] [-r regex] [-R regexi] [-t timeout] [-e retries]
[-l label] [-u units] [-p port-number] [-d delimiter] [-D output-delimiter]
[-m miblist] [-P snmp version] [-L seclevel] [-U secname] [-a authproto]
[-A authpasswd] [-X privpasswd]

[/usr/local/nagios/libexec/check_snmp: invalid option -- 'x']

Check your commands (CCM > Commands > Commands) in CCM, check_snmp could be malformed there.

Hi,

Thank you for your reply. I am using default SNMPwalk wizard, this is not a custom plugin,

How to make this plugin work for SNMP v3

The wizard will eventually end up creating you a service that uses the command "check_snmp", which utilises the plugin "check_snmp".

The error you are seeing is from the plugin (/usr/local/nagios/libexec/ - it doesn't understand an option "x" that it has been passed. If you check the command definition as suggested, you may find the options aren't configured correctly. You should also check the service definition as this can pass additional options to the plugin through the $ARG1$ macro.
