Thanks, yes I was more or less aware of that (I'd been using DTrace since Solaris 10 beta in 2004 or 2003?)... By rollout I really meant "getting the word out there"... that's half the battle in my experience (that's why this post here! :-) What I loved about DTrace was that once it was out, even in beta, it was pretty complete and worked - all the DTrace ports that I've tried, including on Windows (!) a few years ago were very limited or had some showstopper issues. I guess eBPF was like that too some years ago, but by now it's pretty sweet even for more regular consumer who don't keep track of its development. Edit: Oh, wasn't aware of the timeline, I may have some dates (years) wrong in my memory
