* `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` .
2019-05-28 21:15:42 +00:00
* `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 whitelist of events that have been manually vetted to not
include any PII. See [the implementation in
Chromium][trace_event_args_whitelist.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
2019-05-28 21:15:42 +00:00
`disabled-by-default-memory-infra` category is enabled, this contains

An example TraceConfig that roughly matches what Chrome DevTools records:
2018-12-20 12:11:17 +00:00
2019-05-28 21:15:42 +00:00
```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: [ '*' ]
}
