DTrace kicks ass. Everyone knows I love ZFS, but in my opinion DTrace is the most significant and disruptive systems technology in at least 10 years.

Today I gave my talk at ApacheCon; it was well received. I hope that I inspired some people to go use DTrace and look in their systems' underpants.

Here are my slides and the scripts I used for my live demo.

I'll update this entry with the video as soon as I have the link.

I mentioned a Linux port underway. I got the name wrong when I talked about it (sorry Paul!). The person working on the port is Paul Fox, the author of the CRiSP editor. For more information, check out his blog.
