title: Nagios - Host/Service dependancy
body: <p>I am implementing Nagios for a customer.</p>
  
  <p>The customer has the following request;</p>
  
  <p>We have a PC (PC-1) and a server (Server-1). The PC only has ping monitoring in Nagios, the server has Ping monitoring but also a service check (check if Citrix is up). </p>
  
  <p>We would like PC-1 to go to a warning state when the Citrix service on Server-1 is in a down state. The reason we want that is for reporting purposes.</p>
  
  <p>I am aware of service to service dependancy, but I am wondering if this service to host dependancy would work and how :).</p>
  
  <p>Any help is welcome!</p>
  
  <p>Thanks!</p>
