RE: System Monitor

["Burton Strauss" <Burton () FelisCatus org>]

ntop won't show you local processes usage.  It's a network monitor tool

Actually I'm wondering if he doesn't need to check into the app he installed
to see if it might be polling for something.  Polling can cause CPU usage to
peg, but does it in such a way that it usually doesn't impact other apps.
