Perfetto Trace Collection Profiling for Chrome Developers

This tool provides a way for chrome developers to collect perfetto traces and symbolize them.

Startup Tracing

The script profile_chrome_startup runs a chrome trace on android, locates the trace file, and automatically copies it to a local folder.

Example Linux Platform Usage:

tools/tracing/profile_chrome_startup --platform=android

Future Work

We are planning to add symbolization support and trace collection for other platforms.

See the google internal design doc for more details pertaining to this tool: https://docs.google.com/document/d/1BJPbcl5SPjOvuRuP1JSFAUPK3ZWNIS7j1h94rPHRzVE
