======================================================================== Overall the tool has two subcommands: ======================================================================== usage: PINPOINT_TRACES [-h] {fetch,extract} ... Tool to download and aggregate traces from a given Pinpoint job. The tool is intended to be used in two steps: Step 1: Fetch all traces from a Pinpoint job. Example: > pinpoint_traces.py fetch \ --job=https://pinpoint-dot-chromeperf.appspot.com/job/1709f5ff920000 Step 2: Extract all events with a matching name into a CSV file. Example: > pinpoint_traces.py extract --event='.*Looper.dispatch.*' --output events.csv NOTE: Currently only supported on Linux. WARNING: Uses multiprocessing with heavy use of memory and CPU resources in each subprocess. This causes problems when handling SIGINT (when ^C is pressed), instead it is recommended to stop by ^Z and using the shell job control to kill or continue the job (like: kill %1). positional arguments: {fetch,extract} fetch Fetches job_results.csv and the traces mentioned in it extract Extracts information about an event from all downloaded tracesinto a CSV file ======================================================================== The 'fetch' command takes a JOB: ======================================================================== usage: PINPOINT_TRACES fetch [-h] --job JOB required named arguments: --job JOB Pinpoint job ID or URL ======================================================================== The 'extract' command takes a regex and an output file name: ======================================================================== usage: PINPOINT_TRACES extract [-h] -e EVENT -o OUTPUT required named arguments: -e EVENT, --event EVENT Regex to match event names against -o OUTPUT, --output OUTPUT CSV output file name Bug: 1119406 Change-Id: Ief2a3d5ab97c54aa6e98c6095c6fcadbe88e4907 Reviewed-on: https://chromium-review.googlesource.com/c/chromium/src/+/2461323 Commit-Queue: Egor Pasko <pasko@chromium.org> Reviewed-by:John Chen <johnchen@chromium.org> Reviewed-by:
