Design a real-time monitoring system.
Explain how you would ingest signals, detect anomalies, correlate related events, generate alerts, and expose system health to operators. Treat scale, latency, online versus batch processing, evaluation, feature drift, training-serving skew, and failure recovery as requirements to clarify rather than assumptions.
