How do I configure this using the XI UI?
Code: Select all
Excluding Hosts:
If you want to create identical services on numerous hosts or hostgroups, but would like to exclude some hosts from the definition, this can be accomplished by preceding the host or hostgroup with a ! symbol.
define service{
host_name HOST1,HOST2,!HOST3,!HOST4,...,HOSTN
hostgroup_name HOSTGROUP1,HOSTGROUP2,!HOSTGROUP3,!HOSTGROUP4,...,HOSTGROUPN
service_description SOMESERVICE
other service directives ...
}

This is not exactly "straight forward" process in XI (if you want to use the Web UI instead of manually creating the configs and importing them)...
You can go to:
CCM->Services->Manage Hosts->and remove ALL of the assigned hosts. You will add them as a free variable instead, so go to the "Misc Settings" tab->"Manage Variable Definitions" and add:
Variable name = "host_name"
Variable value = "HOST1,HOST2,!HOST3,!HOST4,...,HOSTN"
Save, and Apply Configuration.

I will explore other solutions. This will be a management problem in the long run.
Thanks.
BTW, what is this for? I can see the + which seems to be adding it in front of the hostnames

This has to do with how objects coming through templates are handled.
+ = Additive, template objects and locally defined objects are combined
null = the option is not set
standard = local defined objects are used
Check out the documentation here which explains it with examples:

The template object also has the +, null and standard. What happens if I choose + in the template itself?

If the template also used a template then it would combine that templates objects and it's own objects.
