I can't get custom variables working with a new nagios XI install. I put a test plugin out to make sure it wasn't my plugin. I defined my custom variables in my host template. This works for our nagios core installation, but not nagios xi. Any help would be appreciated.

From objects.cache:

Code: Select all

define host {
	host_name	myhost
	alias	myhost
        ...
        _OS_TYPE	Solaris
	_POC_GROUP	Unix Team
	}

I have the below test plugin running for myhost:

Code: Select all

#!/bin/bash

if [ "1" ]; then
env
echo
echo $NAGIOS_HOSTOS_TYPE

echo "DONE"
date

fi > /tmp/test.bash.txt 2>&1


exit 0

output of /tmp/test.bash.txt:

Code: Select all

TERM=linux
PATH=/sbin:/usr/sbin:/bin:/usr/bin
RUNLEVEL=3
runlevel=3
PWD=/
LANGSH_SOURCED=1
LANG=en_US.UTF-8
PREVLEVEL=N
previous=N
CONSOLETYPE=vt
SHLVL=4
UPSTART_INSTANCE=
UPSTART_EVENTS=runlevel
UPSTART_JOB=rc
_=/bin/env


DONE

I certainly could be incorrect, please do link me to documentation if I am, but I don't believe that is possible. By default Nagios should not export all variables to the env variable for OS use, they are instead used internally with the program and passed to the scripts via defined commands or handlers. These variables are then expanded before exec-ing the full command. You could certainly define your check to send the $_OS_TYPES$ variable and have your script accept and use that.

Thanks. I figured it out. I had to change the below in nagios.cfg
enable_environment_macros=1
