Re: [icinga-users] assigning checks to overlapping hostgroups

[Seth Galitzer]

One more wrinkle on this topic. In another case, using Gunnar's 
solution, I also want to only assign the service if a host var is set. 
Right now, I'm doing this, which doesn't work:

apply Service "bla" {
   assign where {
     var match = [ "a", "b" ]
     var arr = intersection(host.groups, match)
     return arr.len() > 0
   }
} && host.vars.check_flag == true
I've also tried adding an ignore statement instead, which also didn't work:

ignore where host.vars.check_flag != true

I don't always set the check_flag var, only when it is set to true, so 
maybe that's why the ignore doesn't work? Or does order matter when 
combining assign and ignore statements?

Any ideas on how I can accomplish this?

Thanks.

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
