What decision will this measurement support?
Choose a traffic population and time window, then define exactly what is counted. Separate request cache hits from bytes saved, model responses from validated outcomes, and the first attempt from the complete request path. Consistent definitions make a comparison useful even when the system grows more complex.
- Document the units and denominator of each metric.
- Account for sampling, retries, and auxiliary services.
- Retain only the diagnostic detail needed for the intended investigation.
