The port was announced at the Ignite conference last year, and today the instructions, binaries, and source code are now available. > DTrace lets developers and administrators get a detailed look at what their system is doing: they can track kernel function calls, examine properties of running processes, and probe drivers. DTrace commands use the DTrace scripting language, with which users can specify which information is probed, and how to report that information.
