symbolicate-trace

This tool symbolicates cpu_profiler traces produced by Electron's contentTracing system.

The disabled-by-default-cpu_profiler tracing category records a sample of the native stack trace every 50 ms. This can be helpful in tracking down performance issues in native code.

To record such stack samples, include the disabled-by-default-cpu_profiler category in the content tracing configuration:

contentTracing.startRecording({
  included_categories: [
    'disabled-by-default-cpu_profiler',
    // ...
  ]
})
