We Migrated from StatsD to Prometheus in One Month

Описание и применение

Mixpanel перешёл с StatsD на Prometheus за один месяц, улучшив производительность запросов, скорость оповещений и масштабируемость.

Задача

Mixpanel’s existing StatsD-based monitoring stack was hitting scalability limits and lacked the observability features needed for modern cloud workloads.

Результат

The migration completed in one month, improving query performance by 3x, reducing alert latency, and eliminating the high-cardinality bottleneck.

Рабочий процесс

• 1. Conducted a metrics inventory and identified high-cardinality metrics.
• 2. Designed a mapping strategy from StatsD to Prometheus exposition format.
• 3. Implemented Prometheus exporters for existing services.
• 4. Deployed Prometheus server and configured federation for scalability.
• 5. Migrated dashboards from StatsD to Prometheus queries.
• 6. Validated data consistency and performance through load testing.
• 7. Decommissioned legacy StatsD collectors and rolled out the new stack to production.
