Quick thot on MySQL

Had a good question in my MySQL talk about how to monitor performance, and of course I suggested turning on the MySQL slow query log. What I neglected to mention, however, was mytop. This little utility is found in the rpmforge repo and it’s like a top(1) for your mysql queries.

The basis for it is the SHOW PROCESSLIST command, of course. Mytop collects, sorts and colors the output and adds the system summary of key-hits-ratio, query count, etc at the top.
