Parameters

categories  String  (Optional)

Category/tag filter

options  String  (Optional)

Tracing options

bufferUsageReportingInterval  NullableDouble  (Optional)

If set, the agent will issue bufferUsage events at this interval, specified in milliseconds

transferMode  NullableStartTransferMode  (Optional)

Whether to report trace events as series of dataCollected events or to save trace to astream (defaults to `ReportEvents`).

streamFormat  NullableStreamFormat  (Optional)

Trace data format to use. This only applies when using `ReturnAsStream`transfer mode (defaults to `json`).

streamCompression  NullableStreamCompression  (Optional)

Compression format to use. This only applies when using `ReturnAsStream`transfer mode (defaults to `none`)

traceConfig  TraceConfig  (Optional)

traceConfig

perfettoConfig  Byte  (Optional)

Base64-encoded serialized perfetto.protos.TraceConfig protobuf messageWhen specified, the parameters `categories`, `options`, `traceConfig`are ignored.

tracingBackend  NullableTracingBackend  (Optional)

Backend type (defaults to `auto`)

Return Value
