How FAANG Engineers Use Observability to Debug Production

Lucas and Luna explore how senior engineers at companies like Google and Meta use observability — not just monitoring — to debug production issues faster. They break down the three pillars (metrics, logs, traces), explain why dashboards full of green checks can be misleading, and share a concrete example of how a single distributed trace saved a team six hours of debugging. Luna challenges whether most engineers actually use observability tools effectively, and Lucas argues that the real skill is knowing which signals to ignore. The episode closes with practical advice for engineers preparing for system design interviews that now often include observability questions.
