Azure Monitor operational effectiveness requires alignment between the three-tier retention model (93 days platform metrics, 18 months Prometheus, up to 12 years logs) and the dual-track alert lifecycle (system-managed fired/resolved conditions with 30-day alert retention plus user response states) — because alert investigation depends on the underlying metric or log data still being within its retention window, and alert processing rules must account for data availability at each retention tier.
