Response time

[Carroll, Jim P [Contractor]]

You're not going to like this answer.

It's all about trade-offs.  If you're interested in consolidating N checks
on one monitoring server, be prepared for the time between checks to scale
proportionately to the number of checks being done.  Don't expect a server
doing 2,000 checks to behave the same as a server doing 5 checks.  If you're
interested in having one server kept under the microscope with just a ping
test, I'm sure you could tune Nagios to give you pager/e-mail response
between 1-5 seconds.  If you're interested in doing 2,000 checks and having
Nagios alert you in under 5 seconds if *any* of the hosts/services go down
(with 100% determinism), you're being a wee bit optimistic.

Perhaps you'd like to rephrase the question...?
