We Migrated from StatsD to Prometheus in One Month

说明与用途

Mixpanel 在一个月内将监控系统从 StatsD 迁移到 Prometheus，提升了查询性能、告警延迟和可扩展性。

问题

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

结果

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

工作流

• 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.
