Expose Metrics with Prometheus
Track request rate, errors, and duration.
Logs vs Metrics
Logs tell the story of one request. Metrics are numbers aggregated over many requests, so you can see trends like rate and error count at a glance. 📈
Meet Prometheus
Prometheus is the standard tool for collecting these numbers. Your service exposes metrics, and Prometheus regularly reads them for you.
