Hmmmm I don't think I've ever seen an instance where the nagios user can execute a shell script but not the nagios application... with selinux disabled. Might be time to turn on Nagios debugging in nagios/etc/nagios.cfg, by default it will create the file nagios/var/nagios.debug .
So after you have turned on debugging, start nagios, force the command to run and then turn nagios off again so that the log doesn't end up so large you can't find what you are after.

*slaps forehead* are you able to post your command definition for check_rg411?... I think I know what your problem is.

Change your command_line to this:
Code: Select all
command_line $USER1$/check_rg411 $HOSTADDRESS$ $ARG3$
You were missing the trailing $ sign

Thanks for catching that. I am still having issue with returning the information from the script..... so sad.
I am finding this error now in the Nagios log.

Am trying to see what can be causing this.

I was able to duplicate the same error in Nagios 3.4.1.
The debug log was able to provide me with additional details:
