Performance Monitoring - Autosana

Autosana automatically collects performance metrics during test runs across all platforms. After a run completes, a Performance section appears on the run detail page with charts and diagnostics.

Performance monitoring charts showing memory and CPU usage over time

What’s Collected

Android
iOS
Web

Metric	Description
Memory	App memory usage, sampled every ~2 seconds
CPU	App CPU usage over time
Frame rendering	Total frames, slow frames, stutter rate, and render time percentiles
Device RAM	Total device RAM for context (e.g., “350 / 2048 MB”)

Metric	Description
Memory	App memory usage, sampled every ~2 seconds
CPU	App CPU usage over time

iOS metrics are measured from the simulator. Absolute values differ from a real device — use them for comparing across builds and detecting regressions.

iOS performance monitoring is currently not available for local CLI runs. It works for cloud-hosted runs.

Metric	Description
Memory	JS heap usage over time
CPU	Browser CPU usage over time
Core Web Vitals	Largest Contentful Paint, Layout Shift, Interaction Delay
Page timing	Server Response, Page Ready, Fully Loaded
Runtime health	Blocking tasks, total blocked time, page complexity

Web Vitals thresholds follow Google’s recommendations:

Good (green): LCP ≤ 2.5s, CLS ≤ 0.1, INP ≤ 200ms
Needs work (amber): LCP ≤ 4s, CLS ≤ 0.25, INP ≤ 500ms
Poor (red): above those thresholds
