This has be a real blind spot in the node community since inception. It's great to see a company focused on delivering a node runtime that is instrumented in a way that provides large node deployments with the necessary metrics/insights needed for node at scale.

Would be great if they posted some more info on whether or not their instrumentation comes with a cost to performance. Looks like you can enable/disable profiling at runtime without restarting too, which is huge!

> Node.js applications can be debugged and profiled live, without the need to restart, and therefore potentially miss critical state that led to the fault.
