Mytop is one of my classic open source and free console-based (non-gui) monitoring tool for MySQL database written by Jereme Zawodny using Perl language. Mytop runs in a terminal and displays statistics about threads, queries, slow queries, uptime, load, etc. in tabular format, much similar to the Linux top program. Which indirectly helps the administrators to optimize and improve the performance of MySQL to handle large requests and decrease server load.
Mytop program provides a command-line shell interface to monitor real time MySQL threads, queries per second, process list and performance of databases and gives an idea for the database administrator to better optimize the server to handle the heavy load.
