# 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][trace_event_args_allowlist.cc]
  for specifics.
* `included_categories` string[] (optional) - 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[] (optional) - 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[] (optional) - a list of process IDs to
  include in the trace. If not specified, trace all processes.
* `histogram_names` string[] (optional) - 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][memory-infra docs] for more information.

An example TraceConfig that roughly matches what Chrome DevTools records:

<!-- eslint-skip -->

```js
{
  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: ['*']
}
```
