Nagios ignores check_nrpe return code

[Rene Rembarz]

Hi Andreas,

Thanks for your reply. The echo $? Was just something I did to show you guys that check_nrpe correctly captures the return code of the remote plugin and exits with that same return code.

The actual command definition looks like this:

define command {
        command_name check_nrpe
        command_line $USER1$/check_nrpe -H $HOSTADDRESS$ -c $ARG1$ 
        }
 
Cheers,
René
