This is why you really can't measure CPU load on too short a time 
(without some kernel hacking, anyway). You'll usually just get the 
average over 1,5 and 15 minutes, which is what you set your alerts for.

The max_check_attempts variable for settings lets you skip receiving 
notifications for services that spike temporarily (by scheduling 
re-checks and sending a notification only if it receives a non-ok state 
max_check_attempts in a row). Raise it for your CPU load services if you 
think you're receiving too many false positives.
