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.

Well it is nice you found the FAQ entry, but you should relize how little of the OS is distributed under that license. OpenSolaris is 15 million, in some 35,000 files. The closed binaries are less than 300 files. Also those 300 files are not the crown jewels, but drivers and a few program that Sun is still researching owner ship or trying to get permission to distribute.
ZFS, DTrace, brandz, zones, RBAC, fire engine, SMF, predictive self healing. Have all been released.
Those 300 files will be openned or rewritten from scratch in the future. So you can quibble about small details. Or you can embrace and extend.
Linux distros sometimes include closed source drivers, nvidia for one, the openned source versions don't compare so most people used the closed source version.
