We Migrated from StatsD to Prometheus in One Month
Description and use
The team migrated from StatsD to Prometheus in one month, improving storage, querying, and alerting.
Problem
The team needed a more scalable, flexible monitoring stack that could handle high cardinality metrics and provide richer querying capabilities.
Outcome
The migration completed in one month, improving query performance, reducing storage costs, and enhancing alerting capabilities.
Workflow
- 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.
