We Migrated from StatsD to Prometheus in One Month

说明与用途

团队在一个月内将监控从 StatsD 迁移到 Prometheus，提升了存储、查询和告警功能。

问题

The team needed a more scalable, flexible monitoring stack that could handle high cardinality metrics and provide richer querying capabilities.

结果

The migration completed in one month, improving query performance, reducing storage costs, and enhancing alerting capabilities.

工作流

• 1. Assessed current StatsD deployment and identified key metrics to migrate.
• 2. Set up a Prometheus server and configured it to scrape metrics from existing services.
• 3. Replaced StatsD emitters with Prometheus client libraries in microservices.
• 4. Migrated Grafana dashboards to use Prometheus data sources.
• 5. Configured Alertmanager for alerting based on PromQL rules.
• 6. Ran parallel monitoring for a week to validate data consistency.
• 7. Decommissioned StatsD infrastructure after verification.
