This is the best resource I have found for using DTrace under Solaris: http://users.tpg.com.au/adsln4yb/dtrace.html It is great to see DTrace coming to FreeBSD, I've found myself recently developing code on Solaris that I have no intention of actually using under Solaris, just because DTrace is available.
