Host assumed to be up?

[Andreas Ericsson]

Most service checks will do just fine with a normal_check_interval of 5 
minutes. Hard disk checks barely need checking more than once every 
hour, while the company internet pipe and the core switch/router will 
probably need checking just about every second.

We've solved this problem by using three templates.
critical_service_template{} uses a normal_check_interval of 2 minutes, 
and a max_check_attempts of 2 (just minor alarm suppression).
default_service_template{} uses a normal_check_interval of 5 minutes, 
max_check_attempts of 3.
noncritical_service_template uses a normal_check_interval of 120 minutes 
with a max_check_attempts of 3.
All services use retry_check_interval of 1 minute.

Using this method, nagios scales awesomely even on really large systems 
(1200+ checks on 250 hosts).

Cheers,
Sourcerer / Andreas Ericsson
