Loki metrics often disappear after log retention periods expire because logs and metrics have different lifecycles. The solution involves implementing recording rules that extract metrics from logs while they're available, then using remote write to persist these metrics in long-term storage systems. This approach decouples operational metrics from log retention policies, ensuring dashboards and alerts continue working beyond the typical 30-day log retention window.
