General Development This article goes into the motivation and architecture for DTrace -- and describes some of the problems that remain to be solved in system observability. The article also includes a short case-study on using DTrace to find a real problem -- a problem that was ultimately due to some seriously fugly code in a monitoring app.

I'm not a lawyer or anything but it might be possible to just reimplement the kernel layer of DTrace from scratch. I mean it probably just requires certain hooks into the running kernel which already exist for debugging. I'm making this sound trivial and it's really not but legally I think it might be possible. If not there's no reason we can't come up with a work-alike for DTrace.
