dont check service when host down

[Hari Sekhon]

Ton,

   This sounds like a great candidate for scalability to not check 
services on downed hosts?

On a large installation with several hosts down, if the service check 
intervals for broken services increases (as I usually configure it to 
do) then this could degrade the nagios server. You would be forced to 
not have increased service check intervals for downed services.

It would be best if nagios actually did allow configuration of an option 
to not check services for downed hosts. I'm not sure if this should be 
done on a global or host basis though, host/host template is most 
flexible I think.

Could we make this a feature request?
