The Best of Velocity series of webcasts feature exclusive, top-rated sessions from Velocity 2011. These sessions were recorded live and have not been made publicly available until now. In this talk, Bryan Cantrill, VP of Engineering at Joyent, describe his team's experiences developing DTrace-based system visualization of Node.js in an early production environment: the 2010 Node Knockout programmingcontest. He describes the challenges of instrumenting a distributed, dynamic, highly virtualized system -- and what their experiences taught them about the problem, the technologies used to tackle it, and promising approaches.
