Understanding Unhandled Services / Hosts

Hi - would someone be able to explain in detail the behaviour of this? I have a Nagios setup that in the Problems page is showing a host as DOWN - it’s currently failing my default FPING test. It also has a number of simple check_tcp commands run against it, all of which are timing out because obviously with the host down I’m getting a “CRITICAL - Socket timeout after 10 seconds” for them all. BUT when looking in Unhandled Services they don’t appear. The host itself DOES appear in the Unhandled Hosts screen. There are NO comments / acknowledgements in place at all for this host.

Does anyone know the service checks don’t appear as an Unhandled Service?

Thanks - J.
