We Migrated from StatsD to Prometheus in One Month

Description and use

Migrating metrics from StatsD to Prometheus in one month improved scalability and observability for Mixpanel.

Problem

StatsD could not scale to Mixpanel’s growing telemetry volume and lacked native support for Prometheus metrics.

Outcome

The migration completed in one month, improving metric visibility, reducing operational overhead, and enabling scalable alerting.

Workflow

• 1. Assessed current StatsD usage and identified pain points
• 2. Designed a migration plan to expose metrics via Prometheus exporters
• 3. Implemented Prometheus exporters for existing services
• 4. Configured Grafana dashboards to replace StatsD visualizations
• 5. Migrated alerting rules to Prometheus Alertmanager
• 6. Performed staged rollouts and validated metric fidelity
• 7. Decommissioned StatsD infrastructure
