Time-to-First-Signal (TTFS) Metrics, Telemetry, and Benchmarks

Module

Scanner

Status

IMPLEMENTED

Description

TTFS telemetry services on both frontend and backend. Frontend tracks signal rendering timing, backend has performance benchmarks. Deterministic test fixtures for TTFS validation.

Implementation Details

  • Performance Benchmarks:
    • src/Scanner/__Tests/StellaOps.Scanner.WebService.Tests/Benchmarks/TtfsPerformanceBenchmarks.cs - TtfsPerformanceBenchmarks measuring time-to-first-signal for scanner API responses with deterministic test fixtures

E2E Test Plan

  • Run TTFS performance benchmarks and verify time-to-first-signal is within acceptable thresholds for scan initiation
  • Verify TTFS metrics are captured for the full scan lifecycle (submission -> first finding -> complete)
  • Verify deterministic test fixtures produce consistent TTFS measurements across runs
  • Verify TTFS telemetry is available via the scanner WebService API for monitoring dashboards
  • Verify TTFS benchmarks cover different scan sizes (small, medium, large images) with documented baselines
