Pass arguments from service to event handler

[cellact]

Hi,
I'm trying to pass the $ARG4$ argument from a service check to the event handler it is triggering.
I tried adding $ARG4$ to the event handler command but it seems to not pass the original service's $ARG4$

How can I achieve this?

Thanks,
Tal

I believe you can achieve this by using the free variables in the host or service definition.

CGraham is correct, we have some documentation for something similar to this used for restarting services

One important thing to note, which might be confusing is that in the NSClient++ config file (nsc.ini) they use the $ARG1$ and $ARG2$ nomenclature. This represents the first, second, etc argument that you pass to the nrpe command (using the -a switch) and are not related to the $ARG1$, $ARG2$ that you configure in your original check command.

If you post the details of what you're doing, we can suggest a possible setup. Helpful info:

Yes, the event_handler also uses them in Core under the hood, so if you had a command for your event handler like

Code: Select all

define command {
       command_name                             a_test
       command_line                             $USER1$/myevent.sh -a $ARG1$
}

And a config like this

Code: Select all

define host {
        host_name                       10.0.0.1
        use                             linux-server
        check_command                   check-host-alive!!!!!!!!
        event_handler                   test_arg!XXXXXXXXX
        event_handler_enabled           1
        register                        1
        }

It would execute the following

Code: Select all

/usr/local/nagios/libexec/myevent.sh -a XXXXXXXXX

The free variable method worked great.
FYI, I couldn't find a way to edit the service config file and add an argument to be sent to the event handler like you stated:

Code: Select all

define host {
        host_name                       10.0.0.1
        use                             linux-server
        check_command                   check-host-alive!!!!!!!!
        event_handler                   test_arg!XXXXXXXXX
        event_handler_enabled           1
        register                        1
        }

Thanks for your help!

I should have been clearer, there isn't a way to do this in XI
