Topic: A Taste of DTrace on FreeBSD

Introduction & Description of Talk:

During the last year Dr. Robert Watson, one of the co-authors of the most recent "Design and Implementation of the FreeBSD Operating System" and our speaker, George Neville-Neil, have put together both an academic and a professional operating systems course built around using DTrace to show students operating systems internals using a running kernel. This talk is a brief taste of what we teach in the class. Using working examples from both the academic and professional versions of the class we will demonstrate the power of DTrace on FreeBSD in explaining how a modern OS works. The same techniques are also used to examine the system as a whole, including user programs and how they interact with the OS giving students a powerful toolset with which to understand overall system behavior.

(About FreeBSD:)

FreeBSD is an advanced operating system for x86 compatible, amd64 compatible, UltraSPARC, IA-64, PC-98 and ARM architectures. It is derived from BSD, the version of UNIX developed at the University of California, Berkeley. It is developed and maintained by a large team of individuals. Additional platforms are in various stages of development. For information about FreeBSD, visit http://www.freebsd.org.


Addison-Wesley Professional/Prentice Hall PTR/Pearson, and O'Reilly have been kind enough to provide us with review copies of some of their books, which we will continue to raffle off as giveaways at our meetings. The publishers always ask that the persons receiving the books provide a review and/or feedback about their books.

Unigroup would like to thank both publishing companies for the support provided by their User Group programs.

As always, all of the books will be available for review at the start of the meeting.

       ! Students: We are looking for proof that you are
         currently enrolled in classes (rather than working
         full-time), and as such, your Student ID should show
         a CURRENT date.  We have been presented Student IDs
         containing NO dates whatsoever, and in the
         current environment, perpetual/non-expiring access
         to university facilities just does not feel right.
         If your ID contains no date, please bring
         additional proof of current enrollment.  Thanks.
