Design a monitoring system that can send alerts that users can configure.
Asked in the system design stage. Clarify the monitored signals, alert conditions, notification channels, delivery guarantees, and operational constraints before proposing the design.
Discuss ingestion, rule evaluation, optional anomaly detection, configuration storage, alert deduplication, notification delivery, retries, observability, and failure recovery. Explain how you would evaluate the system and protect it from noisy rules, feature drift, training-serving skew, and notification-provider failures.
