View proposal in schedule


Attendees will learn the history and current status of DTrace, as well as a technical overview of how DTrace works and a selection of use cases where DTrace provides valuable debugging information. A number of examples and sample commands will be presented.


DTrace is a powerful tool for analyzing system performance on production systems in real time, originally developed by Sun Microsystems for the Solaris operating system and now available on FreeBSD, OS X and Linux. Linux support is the newest and least mature of the available DTrace implementations.


Attendees should be familiar with a Unix like operating system, and should have experience with Unix shells, text editors, and at least one programming language.
