Time Travel Debugging in Production - Know Your Past to Predict Your Future

Explore time travel debugging techniques for production systems in this 38-minute conference talk from Code BEAM Europe 2022. Learn how to tackle complex debugging scenarios, understand the implications of production issues, and build specialized time-travelling debuggers. Discover approaches to constructing these tools, the constraints they place on system design, and how to effectively analyze and visualize debug traces. Gain insights into making informed trade-offs for time and space overhead in production environments. Aimed at engineers running complex BEAM-based production systems, this talk provides valuable strategies for better understanding and troubleshooting system behavior when things go wrong.
