title: Nagios map change host color on service down
body: <p>i'm running a nagios setup for checking 150+ hosts, some of those hosts have services running on them that i want to check.</p>
  
  <p>i now have all the hosts visable on the map with the correct parent relations.</p>
  
  <p>but now i want the host to change color when one of its services goes down so that i know something is going on.
  how would i go about doing that?</p>
  
  <p>i have looked at the nagios documentation but to no avail</p>
  
  <p>i'm running nagios core 4.1.1 with the nagios plugins 2.1.1</p>
