As far as i know the "Availability" Item under Configuration -> Hosts, is only for internal processing. So why is it shown anyway? I think it is very confusing for a new User seeing his Host Availability as unknown when it is actually online and it's Triggers are also all OK. And if it's really useful for someone ( maybe someone can tell me if he ever uses this information) then it should be exactly documented.
