There is an interesting article by Rick Weisner on sun.com about the use of kstat and libkstat APIs to extract metrics from the Solaris OS. The alternative is a system() call to run a script or external program to extract these metrics, but for performance reasons, you should avoid it. Instead, you should use the appropriate APIs. Have a look at Rick's article and see how the use of kstat and libkstat can make your code faster, cleaner and better.
