While migrating from Core to XI I've come across an issue with some old services that are being used to check some temperature monitors. The error that I'm getting is:

COMMAND: /usr/local/nagios/libexec/check_snmp -H cstemp2.servers.local -p 161 -o 1.3.6.1.4.1.16174.1.1.3.3.3.7.0 -C public -P 1 -w \$_HOSTHUM3\$ -c \$_HOSTHUM3\$ -u %
OUTPUT: check_snmp: Invalid warning threshold - $_HOSTHUM3$

The service contains:

It looks like the '$' character is being escaped when the command runs, but I'm not seeing a way to force it to read the variable. This check works fine in our existing install of Core, but I haven't been able to get it to roll into XI. Is there a configuration setting that I've managed to miss, or a special way that I need to escape the '$' in the variable name?

Where did you define the $_HOSTHUM3$ and $_HOSTHUM3$ variables?

I did a very simple test with a couple of macros, and they seem to be working fine in XI (no escaping).

I have a "check_dir" command defined as:

Code: Select all

$USER1$/check_dir -d $ARG1$ -w $ARG2$ -c $ARG3$ $ARG4$

My service definition:

Code: Select all

define service {
	host_name			localhost
	service_description		check_dir
	use				local-service
	servicegroups			linux-servers-all
	check_command			check_dir!/tmp!$_WAR$!$_CRI$!-f!!!!
	max_check_attempts		1
	check_interval			5
	retry_interval			1
	notification_interval		60
	first_notification_delay	0
	notification_options		c,r,
	notifications_enabled		1
	contacts			nagiosadmin
	_CRI				1000
	_WAR				500
	register			1
	}
