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
 }

  
       
       
       
       
       
       
       
  #   icinga2 daemon -C    
  #   systemctl reload icinga2    
  #   systemctl status icinga2    
  #   multitail /var/log/icinga2/icinga2.log
