As a disinterested third party with no ties to either combatant (nor to Sun), I have to side with cajal here. His initial comment was to the point and technical: he provided two explicit examples of how a sysadmin could use DTrace to trivially discover two types of manifestly useful information. hppnq, on the other hand, characterized those examples as mere "marketing speech" (or "marketing mumbo jumbo") and claimed that they're "trivial to do using other tools" yet somehow failed to provide a single example of those other tools.
And speaking as a former sysadmin with some very minor kernel-hacking experience, I think I can safely say that inspection of code is not "the most common thing to do" for that category of user. Not only is knowledge of kernel internals fairly rare among sysadmins (at least in my experience, which I think is pretty typical), I've never yet met one who wasn't swamped with work. Five-line script vs. unknown hours poring over kernel source...hmmm. Tough call.
Anyway, consider this a gentle plea to get back to useful technical interchange rather than continued personal attacks. And thank you, cajal, for a pair of instructive examples that conveyed far more relevant info than any marketing spiel I've ever seen. (Not that I go out of my way to see a lot of marketing spiels...)
