Module tracing

Structs

• EndParams
  Stop trace events collection. end
• EndReturns
  Stop trace events collection. end
• EventBufferUsage
• EventDataCollected
  Contains a bucket of collected trace events. When tracing is stopped collected events will be sent as a sequence of dataCollected events followed by tracingComplete event. dataCollected
• EventTracingComplete
  Signals that tracing is stopped and there is no trace buffers pending flush, all data were delivered via dataCollected events. tracingComplete
• GetCategoriesParams
  Gets supported tracing categories. getCategories
• GetCategoriesReturns
  Gets supported tracing categories. getCategories
• GetCategoriesReturnsBuilder
• MemoryDumpConfig
  Configuration for memory dump. Used only when “memory-infra” category is enabled. MemoryDumpConfig
• RecordClockSyncMarkerParams
  Record a clock sync marker in the trace. recordClockSyncMarker
• RecordClockSyncMarkerParamsBuilder
• RecordClockSyncMarkerReturns
  Record a clock sync marker in the trace. recordClockSyncMarker
• RequestMemoryDumpParams
  Request a global memory dump. requestMemoryDump
• RequestMemoryDumpParamsBuilder
• RequestMemoryDumpReturns
  Request a global memory dump. requestMemoryDump
• RequestMemoryDumpReturnsBuilder
• StartParams
  Start trace events collection. start
• StartParamsBuilder
• StartReturns
  Start trace events collection. start
• TraceConfig
• TraceConfigBuilder

Enums

• MemoryDumpLevelOfDetail
  Details exposed when memory request explicitly declared. Keep consistent with memory_dump_request_args.h and memory_instrumentation.mojom
• StartTransferMode
  Whether to report trace events as series of dataCollected events or to save trace to a stream (defaults to ReportEvents).
• StreamCompression
  Compression type to use for traces returned via streams.
• StreamFormat
  Data format of a trace. Can be either the legacy JSON format or the protocol buffer format. Note that the JSON format will be deprecated soon.
• TraceConfigRecordMode
  Controls how the trace buffer stores data.
• TracingBackend
  Backend type to use for tracing. chrome uses the Chrome-integrated tracing service and is supported on all platforms. system is only supported on Chrome OS and uses the Perfetto system tracing service. auto chooses system when the perfettoConfig provided to Tracing.start specifies at least one non-Chrome data source; otherwise uses chrome.
