The Death of the Four Golden Signals: Designing Telemetry for Non-Deterministic Infrastructure 

The traditional 'Four Golden Signals' of site reliability engineering (latency, traffic, errors, and saturation) are being reevaluated due to non-deterministic infrastructure. This shift is driven by the complexity of modern software systems. Engineers should consider alternative metrics to accurately measure platform stability. This change requires a rethinking of traditional operational health definitions. The industry is moving towards more nuanced approaches to telemetry design.
