Meituan Database Fault Detection, Diagnosis, and Kernel Observability Practices

Meituan’s Database Autonomy Platform integrates a four‑layer architecture—data collection agents, Kafka/Flink processing, storage back‑ends, and user interfaces—to continuously gather MySQL metrics, apply dynamic statistical thresholds (MAD, boxplot, EVT) for anomaly detection, and diagnose issues through kernel code‑path tracing, transaction instrumentation, and core‑dump analysis for rapid fault recovery.
