Real Time Request Response Metrics Collection

via “comprehensive request statistics collection with response time percentiles and failure tracking”

Python load testing framework for APIs and AI endpoints.

Unique: Implements incremental percentile calculation using histogram binning or T-Digest to avoid storing all response times, reducing memory overhead. Failure categorization by error type (timeout, connection error, HTTP status) enables root-cause analysis without post-processing.

vs others: More detailed than simple throughput metrics (requests/sec) because it captures percentile distributions; more memory-efficient than storing all response times because it uses approximate percentile algorithms.
