htop and mytop are programs similar to the standard top, but monitor in different ways and different functions. htop is an interactive process viewer for Linux. It is a text-mode application (for console or X terminals) and requires ncurses. Tested with Linux 2.4 and 2.6. Read on for info on mytop, an interactive monitor for MySQL.
mytop is a console-based (non-gui) tool for monitoring the threads and overall performance of a MySQL 3.22.x, 3.23.x, and 4.x server. It runs on most Unix systems (including Mac OS X) which have Perl, DBI, and Term::ReadKey installed. And with Term::ANSIColor installed you even get color. If you install Time::HiRes, you'll get good real-time queries/second stats. As of version 0.7, it even runs on Windows (somewhat).
