ActivateTriggersRequest ActivateTriggersResponse AndroidGameInterventionListConfig Data source that lists game modes and game interventions of games
on an Android device. AndroidInputEventConfig Custom configuration for the “android.input.inputevent” data source. AndroidLogConfig AndroidPolledStateConfig Data source that polls for display state. This should only be used for
backward-compatibility; AndroidSystemPropertyConfig should be preferred. AndroidPowerConfig AndroidSdkSyspropGuardConfig Data source that controls the system properties used to guard initialization
of track_event producers (i.e. Skia) in apps using HWUI, and certain
processes like SurfaceFlinger. AndroidSystemPropertyConfig Data source that polls for system properties. AppWakelocksConfig Configuration for the android.app_wakelocks data source. AttachRequest Arguments for rpc Attach. AttachResponse ChangeTraceConfigRequest Arguments for rpc ChangeTraceConfig(). ChangeTraceConfigResponse ChromeConfig ChromiumHistogramSamplesConfig ChromiumSystemMetricsConfig CloneSessionRequest Arguments for rpc CloneSession. CloneSessionResponse CommitDataRequest CommitDataResponse ConsoleConfig DataSourceConfig The configuration that is passed to each data source when starting tracing.
Next id: 136 DataSourceDescriptor This message is sent from Producer(s) to the tracing Service when registering
to advertise their capabilities. It describes the structure of tracing
protos that will be produced by the data source and the supported filters. DetachRequest Arguments for rpc Detach DetachResponse DisableTracingRequest Arguments for rpc DisableTracing(). DisableTracingResponse EnableTracingRequest Arguments for rpc EnableTracing(). EnableTracingResponse EtwConfig Proto definition based on the struct _EVENT_TRACE_PROPERTIES definition
See: https://learn.microsoft.com/en-us/windows/win32/api/evntrace/
ns-evntrace-event_trace_properties FlushRequest Arguments for rpc Flush(). FlushResponse FollowerEvent Additional events associated with a leader.
Configuration is similar to Timebase event. Because data acquisition is
driven by the leader there is no option to configure the clock or the
frequency. FreeBuffersRequest Arguments for rpc FreeBuffers(). FreeBuffersResponse FtraceConfig Next id: 31 FtraceDescriptor GetAsyncCommandRequest GetAsyncCommandResponse GetTraceStatsRequest GetTraceStatsResponse GpuCounterConfig GpuCounterDescriptor Description of GPU counters.
This message is sent by a GPU counter producer to specify the counters
available in the hardware. GpuRenderStagesConfig HeapprofdConfig Configuration for go/heapprofd.
Next id: 28 InitializeConnectionRequest Arguments for rpc InitializeConnection(). InitializeConnectionResponse InodeFileConfig InterceptorConfig Configuration for trace packet interception. Used for diverting trace data to
non-Perfetto sources (e.g., logging to the console, ETW) when using the
Perfetto SDK. IpcFrame JavaHprofConfig Configuration for managed app heap graph snapshots. KernelWakelocksConfig Data source that records kernel (and native) wakelock data. NetworkPacketTraceConfig Network tracing data source that records details on all packets sent or
received by the network. NotifyDataSourceStartedRequest NotifyDataSourceStartedResponse NotifyDataSourceStoppedRequest NotifyDataSourceStoppedResponse ObservableEvents ObserveEventsRequest To stop observing events of a certain type, send a request with the remaining
types. To stop observing completely, send an empty request. ObserveEventsResponse PackagesListConfig Data source that lists details (such as version code) about packages on an
Android device. PerfEventConfig Configuration for the traced_perf profiler. PerfEvents PixelModemConfig Data source that records events from the modem. ProcessStatsConfig ProtoLogConfig Custom configuration for the “android.protolog” data source.
ProtoLog is a logging mechanism that is intented to be more efficient than
logcat. This configures what logs to capture in the tracing instance. ProtoLogGroup QueryCapabilitiesRequest Arguments for rpc QueryCapabilities. QueryCapabilitiesResponse QueryServiceStateRequest Arguments for rpc QueryServiceState. QueryServiceStateResponse ReadBuffersRequest Arguments for rpc ReadBuffers(). ReadBuffersResponse TODO: uint32 buffer_id = 1; RegisterDataSourceRequest RegisterDataSourceResponse RegisterTraceWriterRequest RegisterTraceWriterResponse SaveTraceForBugreportRequest Arguments for rpc SaveTraceForBugreport. SaveTraceForBugreportResponse This response is sent only after the trace was saved into file (if succeeded)
or something failed. StartTracingRequest Arguments for rpc StartTracing(). StartTracingResponse StatsdPullAtomConfig StatsdTracingConfig This file is named ‘statsd_tracing_config.proto’ rather than
‘statsd_config.proto’ (which would be more consistent with the other
config protos) so it doesn’t show up and confuse folks looking for
the existing statsd_config.proto for configuring statsd itself.
Same for the config proto itself. SurfaceFlingerLayersConfig Custom configuration for the “android.surfaceflinger.layers” data source. SurfaceFlingerTransactionsConfig Custom configuration for the “android.surfaceflinger.transactions” data
source. SyncRequest Arguments for rpc Sync(). SyncResponse SysStatsConfig This file defines the configuration for the Linux /proc poller data source,
which injects counters in the trace.
Counters that are needed in the trace must be explicitly listed in the
_counters fields. This is to avoid spamming the trace with all counters
at all times.
The sampling rate is configurable. All polling rates ( _period_ms) need
to be integer multiples of each other.
OK: [10ms, 10ms, 10ms], [10ms, 20ms, 10ms], [10ms, 20ms, 60ms]
Not OK: [10ms, 10ms, 11ms], [10ms, 15ms, 20ms] SystemInfoConfig This data-source does a one-off recording of system information when
the trace starts.
Currently this includes: TestConfig The configuration for a fake producer used in tests. TraceConfig The overall config that is used when starting a new tracing session through
ProducerPort::StartTracing().
It contains the general config for the logging buffer(s) and the configs for
all the data source being enabled. TraceStats Statistics for the internals of the tracing service. TracingServiceCapabilities TracingServiceState Reports the state of the tracing service. Used to gather details about the
data sources connected.
See ConsumerPort::QueryServiceState(). TrackEventCategory TrackEventConfig The following fields define the set of enabled trace categories. Each list
item is a glob. TrackEventDescriptor UnregisterDataSourceRequest UnregisterDataSourceResponse UnregisterTraceWriterRequest UnregisterTraceWriterResponse UpdateDataSourceRequest UpdateDataSourceResponse V8Config VulkanMemoryConfig WindowManagerConfig Custom configuration for the “android.windowmanager” data source. AndroidLogId Values from NDK’s android/log.h. AndroidLogPriority AtomId This enum is obtained by post-processing
AOSP/frameworks/proto_logging/stats/atoms.proto through
AOSP/external/perfetto/tools/update-statsd-descriptor, which extracts one
enum value for each proto field defined in the upstream atoms.proto. BuiltinClock MeminfoCounters Counter definitions for Linux’s /proc/meminfo. ProtoLogLevel VmstatCounters Counter definitions for Linux’s /proc/vmstat.
