Variants§

§

ProfiledFrameSymbols(ProfiledFrameSymbols)

Only used in profile packets.

§

ModuleSymbols(ModuleSymbols)

§

DeobfuscationMapping(DeobfuscationMapping)

§

TrackDescriptor(TrackDescriptor)

Only used by TrackEvent.

§

ProcessDescriptor(ProcessDescriptor)

Deprecated, use TrackDescriptor instead.

§

ThreadDescriptor(ThreadDescriptor)

Deprecated, use TrackDescriptor instead.

§

FtraceEvents(FtraceEventBundle)

Events from the Linux kernel ftrace infrastructure.

§

SynchronizationMarker(Bytes)

This field is emitted at periodic intervals (~10s) and contains always the binary representation of the UUID {82477a76-b28d-42ba-81dc-33326d57a079}. This is used to be able to efficiently partition long traces without having to fully parse them.

§

CompressedPackets(Bytes)

Zero or more proto encoded trace packets compressed using deflate. Each compressed_packets TracePacket (including the two field ids and sizes) should be less than 512KB.

§

ExtensionDescriptor(ExtensionDescriptor)

Data sources can extend the trace proto with custom extension protos (see docs/design-docs/extensions.md). When they do that, the descriptor of their extension proto descriptor is serialized in this packet. This allows trace_processor to deserialize extended messages using reflection even if the extension proto is not checked in the Perfetto repo.

§

NetworkPacket(NetworkPacketEvent)

Represents a single packet sent or received by the network.

§

NetworkPacketBundle(NetworkPacketBundle)

Represents one or more packets sent or received by the network.

§

TrackEventRangeOfInterest(TrackEventRangeOfInterest)

The “range of interest” for track events. See the message definition comments for more details.

§

SurfaceflingerLayersSnapshot(LayersSnapshotProto)

Winscope traces

§

SurfaceflingerTransactions(TransactionTraceEntry)

§

ShellTransition(ShellTransition)

§

ShellHandlerMappings(ShellHandlerMappings)

§

ProtologMessage(ProtoLogMessage)

§

ProtologViewerConfig(ProtoLogViewerConfig)

§

WinscopeExtensions(WinscopeExtensions)

§

EtwEvents(EtwTraceEventBundle)

Events from the Windows etw infrastructure.

§

V8JsCode(V8JsCode)

§

V8InternalCode(V8InternalCode)

§

V8WasmCode(V8WasmCode)

§

V8RegExpCode(V8RegExpCode)

§

V8CodeMove(V8CodeMove)

§

RemoteClockSync(RemoteClockSync)

Clock synchronization with remote machines.

§

PixelModemEvents(PixelModemEvents)

§

PixelModemTokenDatabase(PixelModemTokenDatabase)

§

ForTesting(TestEvent)

This field is only used for testing. In previous versions of this proto this field had the id 268435455 This caused many problems:

protozero decoder does not handle field ids larger than 999.
old versions of protoc produce Java bindings with syntax errors when the field id is large enough.
