I want to be able to assign a service to a host that may be in one of several groups among its list of groups. So if host "A" is in groups 
"foo" and "bar" and service "check_foo" is assigned to hosts that are members of the groups "foo" and "baz", 
then host "A" should run service "check_foo". What would be the correct syntax for this case?

I have the following and it obviously is incorrect:

object Host "A" {
  groups += [ "foo", "bar" ]
}

apply Service "check_foo" {
  assign where host.groups in [ "foo", "baz" ]
}

How about apply for? (Untested)

apply Service "bla" for (hg in host.groups) {

  assign where hg in [ "a", "b" ]
}

That’s going to break if your host is in more than one of the groups you’re 
checking for (because in that case you’re trying to create two „bla“ services).


In my specific use case, this would probably be fine.


A different approach would be intersection checking the array length.

http://docs.icinga.org/icinga2/latest/doc/module/icinga2/chapter/library-reference#global-functions

apply Service"bla" {

  var match = [ "a", "b" ]
  var arr = intersection(host.groups, match)

  assign where arr.len() > 0

}

That’s not going to work because ‚assign where‘ and ‚ignore where’ statements 
are evaluated _before_ all other statements. This should work though:

apply Service "bla" {
   assign where {
     var match = [ "a", "b" ]
     var arr = intersection(host.groups, match)
     return arr.len() > 0
   }
}



This worked perfectly. I need to look more closely at these global 
functions.

Thanks to all for the help.

Kind regards,

I need the correct way to say "assign where <any list member of host.groups that 
matches any member of this list>".

I hope that makes sense. Anybody have any suggestions? Do I need to do this in 
the apply statement somehow to loop through members of host.groups? Or is there 
a better way?

Thanks.
Seth
