Icinga2 | dependencies

Imagine, you have a Switch with 3 NAS on it - the NAS are not often used and Switched off like the Switch itself.
so
the Host-Check to the NAS should only be when Switch is on and hostalive!
the NAS-Service-Check should only be if the NAS ist up = hostalive!

	# cd /etc/icinga2/conf.d
	# mkdir dependence
	# cd dependence
	# vi switch2nas.conf
		object Dependency "switch2nas" { parent_host_name = "swt-03.kozo.ch" child_host_name = "NAS-01.kozo.ch" child_host_name = "NAS-02.kozo.ch" child_host_name = "NAS-03.kozo.ch" states = [ Up ] disable_checks = true disable_notifications = true }
	Go to the Host you wish to add the dependency This will by a Host - Host dependency if the Switch swt-03 is down the NAS-01 get unrechable marked	object Dependency "nas-01-swt-03" { parent_host_name = "swt-03.kozo.ch" child_host_name = "NAS-01.kozo.ch" states = [ Up ] disable_checks = true ignore_soft_states = true disable_notifications = true }
