The "yellow" alarm threshold in Active Monitor for Load Average is 3.  The
"red" alarm threshold is 5.

Load over 1 isn't "bad" -- it just means that there are more processes
waiting for CPU time than the CPU can handle at the moment.  If your load
average is perpetually 3-5 or higher, then you are probably overloading
that particular system and should either shift some traffic to another
server, or try tricks like adding more RAM etc.  You have to take the
entire "health" of the server in account when deciding on a course of
action though...  if the server is running a heavy load, but nobody's
complaining, let it ride. You're not going to wear your CPU out faster
running at higher loads or anything...
