Debugging

Observability vs logging in production: why logs alone are not enough to debug latency, failures, and distributed systems.

How excessive logging can make production debugging harder by obscuring causality, distorting timelines, and changing system behavior under load.

Some bugs surface only under real traffic because production load changes timing, concurrency, and failure behavior even when code paths look identical.

A practical debugging workflow for turning vague failures into testable hypotheses, smaller search spaces, and reliable fixes.
