Check multi IP

Service Monitoring
1

Good morning,

I want to check more than one IP on a host/ more IPs from a host, but I think my config does not work:

Service:

apply Service for (ping => config in host.vars.ping_additional) {
    import "generic-service"
    check_command = "ping"

	vars += config
	vars.ping = ping	
	vars.sla = "workhours"
	
	display_name = "ping-" + vars.descr

	 vars.notification["mail"] = {
        groups = [ "unix" ]
      }

        assign where host.vars.ping_additional != ""
}

Host (example):

object Host		"example" {
    import		"generic-host"
    address =			"IP"
    notes =			"Developement"
    vars.ping_additional["172.0.0.100"] = { descr = "sapascs50ds1" }
    vars.ping_additional["172.0.0.110"] = { descr = "sapascs50ds2" }
}

Icingaweb Output:

Unbenannt

Status OK, but there is no change to critical when the second IP is unreachable.

Is there a better way to check multi IPs for host cluster?
