There are various API's depending on what you want to monitor.  You 
might want to take a look at a project like MenuMeters (http://www.ragingmenace.com/software/menumeters/
) which provides a fairly comprehensive overview of system status and 
provides source code so you can see how it was done.  I'm sure there's 
also some Apple example code that demonstrates aspects of this but I 
can't recall anything that does it all in one project like MenuMeters.
