Google has recently started to release certain parts of their code for various purposes as free software. One interesting piece seems to be this mMAIM, which appears to be similar to http://mtop.sourceforge.net/
"We're releasing a new Open Source project today: Google mMAIM, the MySQL Monitoring And Investigation Module.. mMAIM's purpose is to make a it easy to monitor and analyze MySQL servers and to easily integrate itself into any environment. It can show Master/Slave sync stats, some efficiency stats, can return statistics from most of the "show" commands and more! We look forward to seeing what you think about the project!"
Could this be of interest for you, Mediawiki developers?
