Apdex Score - CI/CD Glossary Definition

Apdex (Application Performance Index) is a standardized score from 0 to 1 that summarizes user satisfaction with response times by classifying requests as satisfied, tolerating, or frustrated against a target threshold T.

The formula

Apdex = (satisfied count + tolerating count / 2) / total samples, where satisfied means response time at or below T and tolerating means between T and 4T.
