An example TraceConfig that roughly matches what Chrome DevTools records:

{
recording_mode: 'record-until-full',
included_categories: [
'devtools.timeline',
'disabled-by-default-devtools.timeline',
'disabled-by-default-devtools.timeline.frame',
'disabled-by-default-devtools.timeline.stack',
'v8.execute',
'blink.console',
'blink.user_timing',
'latencyInfo',
'disabled-by-default-v8.cpu_profiler',
'disabled-by-default-v8.cpu_profiler.hires'
],
excluded_categories: ['*']
}
