I do agre about the modularity idea. "Use it at your own risk".

There's a different kind of alerting that can be useful: thresholds. If 
a given threshold is reached or surpassed (like 95% CPU, or bandwidth 
use, or high temperature etc.), some kind of warning would be a great help.
With a well analyzed baseline and conservatively configured, even with 
the five min. lag, it would be better to be warned about it than not, IMHO.
