Guys, that’s not funny ay all. To tell the truth, I’ve never used SystemTap myself but always treated it as a valid option when your on Linux as there is no dtrace. But hey, read another outstanding review from Brendan Gregg and decide yourself if you could trust it. Just a short excerpt:

To write this post, my system has hung when running SystemTap more than six times (I lost count), requiring a power cycle each time. While this system seems more brittle than others on which I’ve run SystemTap (I usually have to run more than just disktop.stp to hit a crash), I still don’t feel safe using SystemTap in production.

Read the rest – it’s really worth it.
