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, queryable metrics system than StatsD, which had limitations in data retention and alerting.

Outcome

The migration completed in one month, providing scalable storage, richer queries, and improved alerting while maintaining dashboard continuity.

Workflow

• 1. Assessed current StatsD setup and identified gaps.
• 2. Designed Prometheus architecture with remote write to long‑term storage.
• 3. Implemented Prometheus exporters for existing services.
• 4. Migrated dashboards from Grafana to Prometheus data source.
• 5. Configured alerting rules in Prometheus Alertmanager.
• 6. Decommissioned StatsD after validation.
• 7. Monitored performance and adjusted retention policies.
