TraceConfig Object

• recording_mode String (optional) - Can be record-until-full, record-continuously, record-as-much-as-possible or trace-to-console. Defaults to record-until-full.
• trace_buffer_size_in_kb number (optional) - maximum size of the trace recording buffer in kilobytes. Defaults to 100MB.
• trace_buffer_size_in_events number (optional) - maximum size of the trace recording buffer in events.
• enable_argument_filter boolean (optional) - if true, filter event data according to a specific list of events that have been manually vetted to not include any PII. See the implementation in Chromium for specifics.
• included_categories String - a list of tracing categories to include. Can include glob-like patterns using * at the end of the category name. See tracing categories for the list of categories.
• excluded_categories String - a list of tracing categories to exclude. Can include glob-like patterns using * at the end of the category name. See tracing categories for the list of categories.
• included_process_ids number - a list of process IDs to include in the trace. If not specified, trace all processes.
• histogram_names String - a list of histogram names to report with the trace.
• memory_dump_config Record<String, any> (optional) - if the disabled-by-default-memory-infra category is enabled, this contains optional additional configuration for data collection. See the Chromium memory-infra docs for more information.

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: ['*']
}
