Nicholas Herring describes how EVE Online applies distributed tracing and observability across a 20-year-old MMO architecture. The talk focuses on head-based, dynamic exponential moving average (EMA), and deterministic sampling to preserve telemetry fidelity while controlling cost and avoiding performance impact in real-time simulations.
