Dtrace with MySQL 6.0.5 - on a Mac
Employee +0 Vote Up -0Vote Down
For the first time, MySQL includes Dtrace probes in the 6.0 release. On platforms that support Dtrace you can still find out a lot about what's happening, both in the Operating System kernel and in user processes, even without probes in the application. But carefully placed Dtrace probes inserted into the application code can give you a lot more information about what's going on, because they can be mapped to the application functionality. So far only a few probes have been included, but expect more to be added soon.

I decided to take the new probes for a spin. Oh, and rather than do it on a Solaris system, I figured I'd give it a shot on my Intel Core 2 Duo MacBook Pro, since MacOS X 10.5 (Leopard) supports Dtrace.

To begin with I pulled down and built MySQL 6.0.5 from Bit Keeper, thanks to some help from Brian Aker.
