Brendan Gregg, creator of the DTrace Toolkit and author of the book that I know everyone has on your desk (you DO have a copy on your desk right?) Solaris(TM) Performance and Tools: DTrace and MDB Techniques for Solaris 10 and OpenSolaris, is speaking at the Silicon Valley OpenSolaris Users Group tonight!

Come by Santa Clara SCA03 tonight on the Agnews site for a great talk on DTrace. Brendan, like his colleges Bryan Cantrill, Mike Shapiro, Eric Shrock, and Adam Leventhal, has a unique personality and great sense of humor, so you’re not just going to learn but have a great time. Hopefully Brendan’s wife is there with her razor wit as well.

So make sure you come by tonight at 7pm, bring your books for signing by the master and another other Solaris celebs that show up (they travel in packs) and have your notebooks ready to learn how to really dive deep with DTrace.

Visit Alan DuBoff’s blog for details. Remember, even if you can’t make it to the meeting you can call in and participate, so make some time to listen in!

And, on the subject, read about how at Joyent we’re using DTrace to find problems in Ruby 1.8.5 and Rails to help customers like Twitter and contribute back to the Rails community.
