Just in case anyone else spends as long as I did trying to find this mysqltoolkit on sourceforge, I believe it has now been renamed:

I have no idea why sourceforge can’t put a redirect in, since many links point to the old project name (including the one at the top of this article).

As far as I am aware, my query profiler is still the only tool of its kind. My hope is that someday MySQL will provide decent tools in the server itself, which will naturally be better than anything I can provide externally, and make it obsolete. But at this point, it is far from obsolete.

Zend Framework also offers query profiler in its Zend_Db package, i think it's worth a check.</p> Mysql 5.0.37 has provided built-in query profiler, this will save time needed for building another custom commonly-reinventing-the-wheel profiler.

Although our application is not very database intensive, its performance is more dependent on the search functionality provided by lucene, we wanted to see if MySQL is acting as a bottleneck. There is a very nice article about optimizing MySQL server. This article contains how you can use show status to profile the performance of your server. This article tells you how to analyze the server performance by manually looking at the status variables as shown by the command. It also talks of a mysqlreport tool that you can use to format the status variables into something easier to understand.
