Metrics Collection

Definitions

1. The practice of instrumenting applications and infrastructure to emit quantitative measurements — such as request latency, error rates, CPU usage, and queue depths — into a time-series store like Prometheus or Datadog for alerting and dashboarding.

   In plain English: Automatically gathering numerical measurements from your software so you can track how it's performing over time.

   Example: "After adding metrics collection to the payment service, we caught the latency regression before it hit customers."
