DTrace

Yesterday Bryan Cantrill (one of DTrace authors) provided a link to the presentation he along with two other DTrace authors gave recently on advanced DTrace scripting. There are lots of useful tips, tricks and gotchas explained, which might be useful for both newbies and some seasoned DTrace users.

As it's states one the very first slides of the presentation, some of the things presented are quite simple - most of the tips you'd know if you read the documentation carefully, but the tips given are very useful. I've learned lots of new things, so I strongly recommend anyone interested in DTrace to find some time and read it as well. Here is the presentation in a PDF file.
