Getting started with DTracing MySQL

DTrace is a dynamic tracing facility built into the Solaris and Open Solaris operating systems and can be used by system administrators and developers alike to observe the runtime behavior of user level programs and of the operating system itself. On one hand, DTrace can be used to identify potential bottlenecks in the running processes on a production system and on the other DTrace can help you understand the runtime behavior of an external program such as MySQL better.
