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.

Defined in trace_config.proto

Fields:

Field	Type	Description
buffers	BufferConfig[]
data_sources	DataSource[]
builtin_data_sources	BuiltinDataSource
duration_ms	uint32	If specified, the trace will be stopped `duration_ms` after starting. This does not count the time the system is suspended, so we will run for duration_ms of system activity, not wall time. However in case of traces with triggers, see TriggerConfig.trigger_timeout_ms instead.
enable_extra_guardrails	bool	This is set when --dropbox is passed to the Perfetto command line client and enables guardrails that limit resource usage for traces requested by statsd.
lockdown_mode	LockdownModeOperation	Reject producers that are not running under the same UID as the tracing service.
producers	ProducerConfig[]
statsd_metadata	StatsdMetadata	Statsd-specific metadata.
write_into_file	bool	When true && `output_path` is empty, the EnableTracing() request must provide a file descriptor. The service will then periodically read packets out of the trace buffer and store it into the passed file. If `output_path` is not empty no fd should be passed, the service will create a new file and write into that (see comment below).
output_path	string	This must point to a non-existing file. If the file exists the service will NOT overwrite and will fail instead as a security precaution. On Android, when this is used with the system traced, the path must be within /data/misc/perfetto-traces/ or the trace will fail. This option has been introduced in Android R. Before R write_into_file can be used only with the "pass a file descriptor over IPC" mode.
file_write_period_ms	uint32	Optional. If non-zero tunes the write period. A min value of 100ms is enforced (i.e. smaller values are ignored).
max_file_size_bytes	uint64	Optional. When non zero the periodic write stops once at most X bytes have been written into the file. Tracing is disabled when this limit is reached, even if `duration_ms` has not been reached yet.
guardrail_overrides	GuardrailOverrides
deferred_start	bool	When true, data sources are not started until an explicit call to StartTracing() on the consumer port. This is to support early initialization and fast trace triggering. This can be used only when the Consumer explicitly triggers the StartTracing() method. This should not be used in a remote trace config via statsd, doing so will result in a hung trace session.
flush_period_ms	uint32	When set, it periodically issues a Flush() to all data source, forcing them to commit their data into the tracing service. This can be used for quasi-real-time streaming mode and to guarantee some partial ordering of events in the trace in windows of X ms.
flush_timeout_ms	uint32	Wait for this long for producers to acknowledge flush requests. Default 5s.
data_source_stop_timeout_ms	uint32	Wait for this long for producers to acknowledge stop requests. Default 5s.
notify_traceur	bool	Android-only. If set, sends an intent to the Traceur system app when the trace ends to notify it about the trace readiness.
bugreport_score	int32	Android-only. If set to a value > 0, marks the trace session as a candidate for being attached to a bugreport. This field effectively acts as a z-index for bugreports. When Android's dumpstate runs perfetto --save-for-bugreport, traced will pick the tracing session with the highest score (score <= 0 is ignored), will steal its contents, save the trace into a known path and stop prematurely. This field was introduced in Android S.
trigger_config	TriggerConfig
activate_triggers	string[]	When this is non-empty the perfetto command line tool will ignore the rest of this TraceConfig and instead connect to the perfetto service as a producer and send these triggers, potentially stopping or starting traces that were previous configured to use a TriggerConfig.
incremental_state_config	IncrementalStateConfig
allow_user_build_tracing	bool	Additional guardrail used by the Perfetto command line client. On user builds when --dropbox is set perfetto will refuse to trace unless this is also set. Added in Q.
unique_session_name	string	If set the tracing service will ensure there is at most one tracing session with this key.
compression_type	CompressionType
incident_report_config	IncidentReportConfig
statsd_logging	StatsdLogging	Android-only. Not for general use. If specified, sets the logging to statsd of guardrails and checkpoints in the tracing service. perfetto_cmd sets this to enabled (if not explicitly set in the config) when specifying --upload.
trace_uuid_msb	int64	An identifier clients can use to tie this trace to other logging. Alternative encoding of trace_uuid as two int64s.
trace_uuid_lsb	int64
trace_filter	TraceFilter
android_report_config	AndroidReportConfig
cmd_trace_start_delay	CmdTraceStartDelay

TraceConfig.BufferConfig

Defined in trace_config.proto

Fields:

Field	Type	Description
size_kb	uint32
fill_policy	FillPolicy

TraceConfig.BufferConfig.FillPolicy

Defined in trace_config.proto

Enum values:

Name	Value	Description
UNSPECIFIED	0
RING_BUFFER	1	Default behavior. The buffer operates as a conventional ring buffer. If the writer is faster than the reader (or if the reader reads only after tracing is stopped) newly written packets will overwrite old packets.
DISCARD	2	Behaves like RING_BUFFER as long as there is space in the buffer or the reader catches up with the writer. As soon as the writer hits an unread chunk, it stops accepting new data in the buffer.

TraceConfig.DataSource

Defined in trace_config.proto

Fields:

Field	Type	Description
config	protos.DataSourceConfig	Filters and data-source specific config. It contains also the unique name of the data source, the one passed in the DataSourceDescriptor when they register on the service.
producer_name_filter	string[]	Optional. If multiple producers (~processes) expose the same data source and either `producer_name_filter` or `producer_name_regex_filter` is set, the data source is enabled only for producers whose names match any of the filters. `producer_name_filter` has to be an exact match, while `producer_name_regex_filter` is a regular expression. This allows to enable a data source only for specific processes. The "repeated" fields have OR semantics: specifying a filter ["foo", "bar"] will enable data sources on both "foo" and "bar" (if they exist).
producer_name_regex_filter	string[]

DataSourceConfig

The configuration that is passed to each data source when starting tracing.

Defined in data_source_config.proto

Fields:

Field	Type	Description
name	string	Data source unique name, e.g., "linux.ftrace". This must match the name passed by the data source when it registers (see RegisterDataSource()).
target_buffer	uint32	The index of the logging buffer where TracePacket(s) will be stored. This field doesn't make a major difference for the Producer(s). The final logging buffers, in fact, are completely owned by the Service. We just ask the Producer to copy this number into the chunk headers it emits, so that the Service can quickly identify the buffer where to move the chunks into without expensive lookups on its fastpath.
trace_duration_ms	uint32	Set by the service to indicate the duration of the trace. DO NOT SET in consumer as this will be overridden by the service.
stop_timeout_ms	uint32	Set by the service to indicate how long it waits after StopDataSource. DO NOT SET in consumer as this will be overridden by the service.
enable_extra_guardrails	bool	Set by the service to indicate whether this tracing session has extra guardrails. DO NOT SET in consumer as this will be overridden by the service.
session_initiator	SessionInitiator	Set by the service to indicate which user initiated this trace. DO NOT SET in consumer as this will be overridden by the service.
tracing_session_id	uint64	Set by the service to indicate which tracing session the data source belongs to. The intended use case for this is checking if two data sources, one of which produces metadata for the other one, belong to the same trace session and hence should be linked together. This field was introduced in Aug 2018 after Android P. DO NOT SET in consumer as this will be overridden by the service.
ftrace_config	FtraceConfig	Data source name: linux.ftrace
inode_file_config	InodeFileConfig	Data source name: linux.inode_file_map
process_stats_config	ProcessStatsConfig	Data source name: linux.process_stats
sys_stats_config	SysStatsConfig	Data source name: linux.sys_stats
heapprofd_config	HeapprofdConfig	Data source name: android.heapprofd Introduced in Android 10.
java_hprof_config	JavaHprofConfig	Data source name: android.java_hprof Introduced in Android 11.
android_power_config	AndroidPowerConfig	Data source name: android.power
android_log_config	AndroidLogConfig	Data source name: android.log

perf_event_config	PerfEventConfig	Data source name: linux.perf
vulkan_memory_config	VulkanMemoryConfig	Data source name: vulkan.memory_tracker
track_event_config	TrackEventConfig	Data source name: track_event
android_polled_state_config	AndroidPolledStateConfig	Data source name: android.polled_state
android_system_property_config	AndroidSystemPropertyConfig	Data source name: android.system_property
statsd_tracing_config	StatsdTracingConfig	Data source name: android.statsd
system_info_config	SystemInfoConfig	Data source name: linux.system_info
chrome_config	ChromeConfig	Chrome is special as it doesn't use the perfetto IPC layer. We want to avoid proto serialization and de-serialization there because that would just add extra hops on top of the Mojo ser/des. Instead we auto-generate a C++ class for it so it can pass around plain C++ objets.
interceptor_config	InterceptorConfig	If an interceptor is specified here, packets for this data source will be rerouted to the interceptor instead of the main trace buffer. This can be used, for example, to write trace data into ETW or for logging trace points to the console. Note that interceptors are only supported by data sources registered through the Perfetto SDK API. Data sources that don't use that API (e.g., traced_probes) may not support interception.
legacy_config	string	This is a fallback mechanism to send a free-form text config to the producer. In theory this should never be needed. All the code that is part of the platform (i.e. traced service) is supposed to not truncate the trace config proto and propagate unknown fields. However, if anything in the pipeline (client or backend) ends up breaking this forward compat plan, this field will become the escape hatch to allow future data sources to get some meaningful configuration.
for_testing	TestConfig	This field is only used for testing.

DataSourceConfig.SessionInitiator

Defined in data_source_config.proto

Enum values:

Name	Value	Description
SESSION_INITIATOR_UNSPECIFIED	0
SESSION_INITIATOR_TRUSTED_SYSTEM	1	This trace was initiated from a trusted system app has DUMP and USAGE_STATS permission. This system app is expected to not expose the trace to the user of the device. This is determined by checking the UID initiating the trace.

FtraceConfig

Defined in ftrace_config.proto

Fields:

Field	Type	Description
ftrace_events	string[]
atrace_categories	string[]
atrace_apps	string[]
buffer_size_kb	uint32	Per-CPU* buffer size.
drain_period_ms	uint32
compact_sched	CompactSchedConfig
symbolize_ksyms	bool	Enables symbol name resolution against /proc/kallsyms. It requires that either traced_probes is running as root or that kptr_restrict has been manually lowered. It does not disclose KASLR, symbol addresses are mangled.
ksyms_mem_policy	KsymsMemPolicy
initialize_ksyms_synchronously_for_testing	bool	By default the kernel symbolizer is lazily initialized on a deferred task to reduce ftrace's time-to-start-recording. Unfortunately that makes ksyms integration tests hard. This flag forces the kernel symbolizer to be initialized synchronously on the data source start and hence avoiding timing races in tests. DEPRECATED in v28 / Android U. This is now the default behavior, setting it to true is a no-op.
throttle_rss_stat	bool	When this boolean is true AND the ftrace_events contains "kmem/rss_stat", this option causes traced_probes to enable the "kmem/rss_stat_throttled" event instad if present, and fall back to "kmem/rss_stat" if not present. The historical context for this is the following: - Up to Android S (12), the rss_stat was internally throttled in its kernel implementation. - A change introduced in the kernels after S has introduced a new "rss_stat_throttled" making the original "rss_stat" event unthrottled (hence very spammy). - Not all Android T/13 devices will receive a new kernel though, hence we need to deal with both cases. For more context: go/rss-stat-throttled. does nothing.
disable_generic_events	bool	If true, avoid enabling events that aren't statically known by traced_probes. Otherwise, the default is to emit such events as GenericFtraceEvent protos. Prefer to keep this flag at its default. This was added for Android tracing, where atrace categories and/or atrace HAL requested events can expand to events that aren't of interest to the tracing user. Introduced in: Android T.
syscall_events	string[]	The list of syscalls that should be recorded by sys_{enter,exit} ftrace events. When empty, all syscalls are recorded. If neither sys_{enter,exit} are enabled, this setting has no effect. Example: ["sys_read", "sys_open"]. Introduced in: Android U.

FtraceConfig.CompactSchedConfig

Configuration for compact encoding of scheduler events. When enabled (and recording the relevant ftrace events), specific high-volume events are encoded in a denser format than normal.

Defined in ftrace_config.proto

Fields:

Field	Type	Description
enabled	bool	If true, and sched_switch or sched_waking ftrace events are enabled, record those events in the compact format.

FtraceConfig.KsymsMemPolicy

When symbolize_ksyms=true, tetermines whether the traced_probes daemon should keep the symbol map in memory (and reuse it for future tracing sessions) or clear it (saving memory) and re-create it on each tracing session (wasting cpu and wall time). The tradeoff is roughly: KSYMS_RETAIN: pay a fixed ~1.2 MB cost after the first trace. KSYMS_CLEANUP_ON_STOP: pay a ~300-500ms cost when starting each trace. Default behavior: KSYMS_CLEANUP_ON_STOP.

Defined in ftrace_config.proto

Enum values:

Name	Value	Description
KSYMS_UNSPECIFIED	0
KSYMS_CLEANUP_ON_STOP	1
KSYMS_RETAIN	2

InodeFileConfig

Defined in inode_file_config.proto

Fields:

Field	Type	Description
scan_interval_ms	uint32	How long to pause between batches.
scan_delay_ms	uint32	How long to wait before the first scan in order to accumulate inodes.
scan_batch_size	uint32	How many inodes to scan in one batch.
do_not_scan	bool	Do not scan for inodes not found in the static map.
scan_mount_points	string[]	If non-empty, only scan inodes corresponding to block devices named in this list.
mount_point_mapping	MountPointMappingEntry[]	When encountering an inode belonging to a block device corresponding to one of the mount points in this map, scan its scan_roots instead.

ProcessStatsConfig

Defined in process_stats_config.proto

Fields:

Field	Type	Description
quirks	Quirks[]
scan_all_processes_on_start	bool	If enabled all processes will be scanned and dumped when the trace starts.
record_thread_names	bool	If enabled thread names are also recoded (this is redundant if sched_switch is enabled).
proc_stats_poll_ms	uint32	If > 0 samples counters (see process_stats.proto) from /proc/pid/status and oom_score_adj every X ms. This is required to be > 100ms to avoid excessive CPU usage.
proc_stats_cache_ttl_ms	uint32	This is required to be either = 0 or a multiple of `proc_stats_poll_ms` (default: `proc_stats_poll_ms`). If = 0, will be set to `proc_stats_poll_ms`. Non-multiples will be rounded down to the nearest multiple.

ProcessStatsConfig.Quirks

Defined in process_stats_config.proto

Enum values:

Name	Value	Description
QUIRKS_UNSPECIFIED	0
DISABLE_INITIAL_DUMP	1	This has been deprecated and ignored as per 2018-05-01. Full scan at startup is now disabled by default and can be re-enabled using the `scan_all_processes_on_start` arg.
DISABLE_ON_DEMAND	2

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]

Defined in sys_stats_config.proto

Fields:

Field	Type	Description
meminfo_period_ms	uint32	Polls /proc/meminfo every X ms, if non-zero. This is required to be > 10ms to avoid excessive CPU usage. Cost: 0.3 ms [read] + 0.07 ms [parse + trace injection]
meminfo_counters	MeminfoCounters[]	If empty all known counters are reported. Otherwise, only the counters specified below are reported.
vmstat_period_ms	uint32	Polls /proc/vmstat every X ms, if non-zero. This is required to be > 10ms to avoid excessive CPU usage. Cost: 0.2 ms [read] + 0.3 ms [parse + trace injection]
vmstat_counters	VmstatCounters[]
stat_period_ms	uint32	Pols /proc/stat every X ms, if non-zero. This is required to be > 10ms to avoid excessive CPU usage. Cost: 4.1 ms [read] + 1.9 ms [parse + trace injection]
stat_counters	StatCounters[]
devfreq_period_ms	uint32	Polls /sys/devfreq/*/curfreq every X ms, if non-zero. This is required to be > 10ms to avoid excessive CPU usage. This option can be used to record unchanging values. Updates from frequency changes can come from ftrace/set_clock_rate.
cpufreq_period_ms	uint32	Polls /sys/devices/system/cpu/cpu*/cpufreq/cpuinfo_cur_freq every X ms. This is required to be > 10ms to avoid excessive CPU usage.
buddyinfo_period_ms	uint32	Polls /proc/buddyinfo every X ms, if non-zero. This is required to be > 10ms to avoid excessive CPU usage.

HeapprofdConfig

Configuration for go/heapprofd.

Defined in heapprofd_config.proto

Fields:

Field	Type	Description
sampling_interval_bytes	uint64	Sampling rate for all heaps not specified via heap_sampling_intervals. These are: * All heaps if heap_sampling_intervals is empty. * Those profiled due to all_heaps and not named in heaps if heap_sampling_intervals is not empty. * The implicit libc.malloc heap if heaps is empty. Set to 1 for perfect accuracy. Otherwise, sample every sample_interval_bytes on average. See https://perfetto.dev/docs/data-sources/native-heap-profiler#sampling-interval for more details. BUGS Before Android 12, setting this to 0 would crash the target process. N.B. This must be explicitly set to a non-zero value for all heaps (with this field or with heap_sampling_intervals), otherwise the producer will not start.
adaptive_sampling_shmem_threshold	uint64	If less than the given numbers of bytes are left free in the shared memory buffer, increase sampling interval by a factor of two. Adaptive sampling is disabled when set to 0.
adaptive_sampling_max_sampling_interval_bytes	uint64	Stop doubling the sampling_interval once the sampling interval has reached this value.
process_cmdline	string[]	E.g. surfaceflinger, com.android.phone This input is normalized in the following way: if it contains slashes, everything up to the last slash is discarded. If it contains "@", everything after the first @ is discared. E.g. /system/bin/surfaceflinger@1.0 normalizes to surfaceflinger. This transformation is also applied to the processes' command lines when matching.
pid	uint64[]	For watermark based triggering or local debugging.
target_installed_by	string[]	Only profile target if it was installed by one of the packages given. Special values are: * @system: installed on the system partition * @product: installed on the product partition * @null: sideloaded Supported on Android 12+.
heaps	string[]	Which heaps to sample, e.g. "libc.malloc". If left empty, only samples "malloc". Introduced in Android 12.
exclude_heaps	string[]	Which heaps not to sample, e.g. "libc.malloc". This is useful when used in combination with all_heaps; Introduced in Android 12.
stream_allocations	bool
heap_sampling_intervals	uint64[]	If given, needs to be the same length as heaps and gives the sampling interval for the respective entry in heaps. Otherwise, sampling_interval_bytes is used. It is recommended to set sampling_interval_bytes to a reasonable default value when using this, as a value of 0 for sampling_interval_bytes will crash the target process before Android 12. Introduced in Android 12. All values must be non-zero or the producer will not start.
all_heaps	bool	Sample all heaps registered by target process. Introduced in Android 12.
all	bool	Profile all processes eligible for profiling on the system. See https://perfetto.dev/docs/data-sources/native-heap-profiler#heapprofd-targets for which processes are eligible. On unmodified userdebug builds, this will lead to system crashes. Zygote will crash when trying to launch a new process as it will have an unexpected open socket to heapprofd. heapprofd will likely be overloaded by the amount of data for low sampling intervals.
min_anonymous_memory_kb	uint32	Do not profile processes whose anon RSS + swap < given value. Introduced in Android 11.
max_heapprofd_memory_kb	uint32	Stop profile if heapprofd memory usage goes beyond the given value. Introduced in Android 11.
max_heapprofd_cpu_secs	uint64	Stop profile if heapprofd CPU time since start of this data-source goes beyond given value. Introduced in Android 11.
skip_symbol_prefix	string[]	Do not emit function names for mappings starting with this prefix. E.g. /system to not emit symbols for any system libraries.
continuous_dump_config	ContinuousDumpConfig	Dump at a predefined interval.
shmem_size_bytes	uint64	Size of the shared memory buffer between the profiled processes and heapprofd. Defaults to 8 MiB. If larger than 500 MiB, truncated to 500 MiB. Needs to be: * at least 8192, * a power of two, * a multiple of 4096.
block_client	bool	When the shmem buffer is full, block the client instead of ending the trace. Use with caution as this will significantly slow down the target process.
block_client_timeout_us	uint32	If set, stop the trace session after blocking the client for this timeout. Needs to be larger than 100 us, otherwise no retries are done. Introduced in Android 11.
no_startup	bool	Do not profile processes from startup, only match already running processes. Can not be set at the same time as no_running. Introduced in Android 11.
no_running	bool	Do not profile running processes. Only match processes on startup. Can not be set at the same time as no_startup. Introduced in Android 11.
dump_at_max	bool	Cause heapprofd to emit a single dump at the end, showing the memory usage at the point in time when the sampled heap usage of the process was at its maximum. This causes ProfilePacket.HeapSample.self_max to be set, and self_allocated and self_freed to not be set. Introduced in Android 11.
disable_fork_teardown	bool	Escape hatch if the session is being torn down because of a forked child that shares memory space, but is not correctly identified as a vforked child. Introduced in Android 11.
disable_vfork_detection	bool	We try to automatically detect when a target applicatation vforks but then does a memory allocation (or free). This auto-detection can be disabled with this. Introduced in Android 11.

HeapprofdConfig.ContinuousDumpConfig

JavaHprofConfig

Configuration for managed app heap graph snapshots.

Defined in java_hprof_config.proto

Fields:

Field	Type	Description
process_cmdline	string[]	Command line allowlist, matched against the /proc//cmdline (not the comm string). The semantics of this field were changed since its original introduction. On Android T+ (13+), this field can specify a single wildcard (), and the profiler will attempt to match it in two possible ways: if the pattern starts with a '/', then it is matched against the first segment of the cmdline (i.e. argv0). For example "/bin/e" would match "/bin/echo". otherwise the pattern is matched against the part of argv0 corresponding to the binary name (this is unrelated to /proc/pid/exe). For example "echo" would match "/bin/echo". On Android S (12) and below, both this pattern and /proc/pid/cmdline get normalized prior to an exact string comparison. Normalization is as follows: (1) trim everything beyond the first null or "@" byte; (2) if the string contains forward slashes, trim everything up to and including the last one. Implementation note: in either case, at most 511 characters of cmdline are considered.
pid	uint64[]	For watermark based triggering or local debugging.
target_installed_by	string[]	Only profile target if it was installed by one of the packages given. Special values are: * @system: installed on the system partition * @product: installed on the product partition * @null: sideloaded Supported on Android 12+.
continuous_dump_config	ContinuousDumpConfig	Dump at a predefined interval.
min_anonymous_memory_kb	uint32	Do not profile processes whose anon RSS + swap < given value.
dump_smaps	bool	Include the process' /proc/self/smaps. This only shows maps that: * start with /system * start with /vendor * start with /data/app * contain "extracted in memory from Y", where Y matches any of the above
ignored_types	string[]	Exclude objects of the following types from the profile. This can be useful if lots of uninteresting objects, e.g. "sun.misc.Cleaner".

JavaHprofConfig.ContinuousDumpConfig

If dump_interval_ms != 0, the following configuration is used.

Defined in java_hprof_config.proto

Fields:

Field	Type	Description

PerfEventConfig

Configuration for the traced_perf profiler.

Example config for basic cpu profiling: perf_event_config { timebase { frequency: 80 } callstack_sampling { scope { target_cmdline: "surfaceflinger" target_cmdline: "system_server" } kernel_frames: true } }

Defined in perf_event_config.proto

Fields:

Field	Type	Description
timebase	PerfEvents.Timebase	What event to sample on, and how often. Defined in common/perf_events.proto.
callstack_sampling	CallstackSampling	If set, the profiler will sample userspace processes' callstacks at the interval specified by the `timebase`. If unset, the profiler will record only the event counts.
ring_buffer_read_period_ms	uint32	How often the per-cpu ring buffers are read by the producer. If unset, an implementation-defined default is used.
ring_buffer_pages	uint32	Size (in 4k pages) of each per-cpu ring buffer that is filled by the kernel. If set, must be a power of two. If unset, an implementation-defined default is used.
max_enqueued_footprint_kb	uint64	Drop samples if the heap memory held by the samples in the unwinder queue is above the given limit. This counts the memory across all concurrent data sources (not just this one's), and there is no fairness guarantee - the whole quota might be used up by a concurrent source.
max_daemon_memory_kb	uint32	Stop the data source if traced_perf's combined {RssAnon + Swap} memory footprint exceeds this value.
remote_descriptor_timeout_ms	uint32	Timeout for the remote /proc//{maps,mem} file descriptors for a sampled process. This is primarily for Android, where this lookup is asynchronous. As long as the producer is waiting, the associated samples will be kept enqueued (putting pressure on the capacity of the shared unwinding queue). Once a lookup for a process expires, all associated samples are discarded. However, if the lookup still succeeds after the timeout, future samples will be handled normally. If unset, an implementation-defined default is used.
unwind_state_clear_period_ms	uint32	Optional period for clearing state cached by the unwinder. This is a heavy operation that is only necessary for traces that target a wide set of processes, and require the memory footprint to be reset periodically. If unset, the cached state will not be cleared.
target_installed_by	string[]	If set, only profile target if it was installed by a package with one of these names. Special values: * "@system": installed on the system partition * "@product": installed on the product partition * "@null": sideloaded Supported on Android 12+.
all_cpus	bool	Note: legacy configs had to set `all_cpus` to true to pass parsing. We rely on this to detect such configs.
sampling_frequency	uint32
kernel_frames	bool
target_pid	int32[]
target_cmdline	string[]
exclude_pid	int32[]
exclude_cmdline	string[]
additional_cmdline_count	uint32

PerfEvents.Timebase

What event to sample on, and how often. Commented from the perspective of its use in PerfEventConfig.

Defined in perf_events.proto

Fields:

Field	Type	Description
frequency	uint64	Per-cpu sampling frequency in Hz, as requested from the kernel. Not the same as 1/period. Details: the actual sampling will still be based on a period, but the kernel will dynamically adjust it based on the observed event rate, to approximate this frequency. Works best with steady-rate events like timers.
period	uint64	Per-cpu sampling will occur every `period` counts of `event`. Prefer `frequency` by default, as it's easier to oversample with a fixed period.
counter	Counter
tracepoint	Tracepoint
raw_event	RawEvent
timestamp_clock	PerfClock	If set, samples will be timestamped with the given clock. If unset, the clock is chosen by the implementation. For software events, prefer PERF_CLOCK_BOOTTIME. However it cannot be used for hardware events (due to interrupt safety), for which the recommendation is to use one of the monotonic clocks.
name	string	Optional arbitrary name for the event, to identify it in the parsed trace. Does not affect the profiling itself. If unset, the trace parser will choose a suitable name.

PerfEvents.Counter

Builtin counter names from the uapi header. Commented with their perf tool aliases. finite), and generally make this list as extensive as possible. Excluding things like dynamic PMUs since those don't fit into a static enum.

PerfEvents.Tracepoint

Defined in perf_events.proto

Fields:

Field	Type	Description
name	string	Group and name for the tracepoint, acceptable forms: * "sched/sched_switch" * "sched:sched_switch"
filter	string	Optional field-level filter for the tracepoint. Only events matching this filter will be counted (and therefore contribute to the sampling period). Example: "prev_pid >= 42 && next_pid == 0". For full syntax, see kernel documentation on "Event filtering": https://www.kernel.org/doc/Documentation/trace/events.txt

PerfEvents.RawEvent

Syscall-level description of the event, propagated to the perf_event_attr struct. Primarily for local use-cases, since the event availability and encoding is hardware-specific.

Defined in perf_events.proto

Fields:

Field	Type	Description
type	uint32
config	uint64
config1	uint64
config2	uint64

PerfEvents.PerfClock

Subset of clocks that is supported by perf timestamping. CLOCK_TAI is excluded since it's not expected to be used in practice, but would require additions to the trace clock synchronisation logic.

Defined in perf_events.proto

Enum values:

Name	Value	Description
UNKNOWN_PERF_CLOCK	0
PERF_CLOCK_REALTIME	1
PERF_CLOCK_MONOTONIC	2
PERF_CLOCK_MONOTONIC_RAW	3
PERF_CLOCK_BOOTTIME	4

PerfEventConfig.CallstackSampling

Defined in perf_event_config.proto

Fields:

Field	Type	Description
scope	Scope	Defines a set of processes for which samples are retained/skipped. If unset, all samples are kept, but beware that it will be very heavy on the stack unwinder, which might start dropping samples due to overload.
kernel_frames	bool	If true, callstacks will include the kernel-space frames. Such frames can be identified by a magical "kernel" string as their mapping name. Requires traced_perf to be running as root, or kptr_restrict to have been manually unrestricted. On Android, the platform should do the right thing on debug builds. This does not disclose KASLR, as only the function names are emitted.
user_frames	UnwindMode	Whether to record and unwind userspace callstacks. If unset, defaults to including userspace (UNWIND_DWARF) both for backwards compatibility and as the most common default (this defaulting is only applicable if the outer CallstackSampling message is explicitly set).

PerfEventConfig.Scope

Defined in perf_event_config.proto

Fields:

Field	Type	Description
target_pid	int32[]	Process ID (TGID) allowlist. If this list is not empty, only matching samples will be retained. If multiple allow/deny-lists are specified by the config, then all of them are evaluated for each sampled process.
target_cmdline	string[]	Command line allowlist, matched against the /proc//cmdline (not the comm string). The semantics of this field were changed since its original introduction. On Android T+ (13+), this field can specify a single wildcard (), and the profiler will attempt to match it in two possible ways: if the pattern starts with a '/', then it is matched against the first segment of the cmdline (i.e. argv0). For example "/bin/e" would match "/bin/echo". otherwise the pattern is matched against the part of argv0 corresponding to the binary name (this is unrelated to /proc/pid/exe). For example "echo" would match "/bin/echo". On Android S (12) and below, both this pattern and /proc/pid/cmdline get normalized prior to an exact string comparison. Normalization is as follows: (1) trim everything beyond the first null or "@" byte; (2) if the string contains forward slashes, trim everything up to and including the last one. Implementation note: in either case, at most 511 characters of cmdline are considered.
exclude_pid	int32[]	List of excluded pids.
exclude_cmdline	string[]	List of excluded cmdlines. See description of `target_cmdline` for how this is handled.
additional_cmdline_count	uint32	Number of additional command lines to sample. Only those which are neither explicitly included nor excluded will be considered. Processes are accepted on a first come, first served basis.
process_shard_count	uint32	If set to N, all encountered processes will be put into one of the N possible bins, and only one randomly-chosen bin will be selected for unwinding. The binning is simply "pid % N", under the assumption that low-order bits of pids are roughly uniformly distributed. Other explicit inclusions/exclusions in this `Scope` message are still respected. The profiler will report the chosen shard in PerfSampleDefaults, and the values will be queryable in trace processor under the "stats" table as "perf_process_shard_count" and "perf_chosen_process_shard". NB: all data sources in a config that set `process_shard_count` must set it to the same value. The profiler will choose one bin for all those data sources.

PerfEventConfig.UnwindMode

Defined in perf_event_config.proto

Enum values:

Name	Value	Description

Fields:

Field	Type	Description

enabled_categories	string[]	Default: []
disabled_tags	string[]	Default: ["slow", "debug"]
enabled_tags	string[]	Default: []
disable_incremental_timestamps	bool	Default: false (i.e. enabled by default)
timestamp_unit_multiplier	uint64	Allows to specify a custom unit different than the default (ns). Also affects thread timestamps if enable_thread_time_sampling = true. A multiplier of 1000 means that a timestamp = 3 should be interpreted as 3000 ns = 3 us. Default: 1 (if unset, it should be read as 1).
filter_debug_annotations	bool	Default: false (i.e. debug_annotations is NOT filtered out by default) When true, any debug annotations provided as arguments to the TRACE_EVENT macros are not written into the trace. Typed arguments will still be emitted even if set to true.
enable_thread_time_sampling	bool	Default : false (i.e. disabled) When true, the SDK samples and emits the current thread time counter value for each event on the current thread's track. This value represents the total CPU time consumed by that thread since its creation. Note that if a thread is not scheduled by OS for some duration, that time won't be included in thread_time. Learn more : "CLOCK_THREAD_CPUTIME_ID" flag at https://linux.die.net/man/3/clock_gettime
filter_dynamic_event_names	bool	Default: false (i.e. dynamic event names are NOT filtered out by default) When true, event_names wrapped in perfetto::DynamicString will be filtered out.

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.

max_messages_per_second	uint32	The maximum number of messages which should be sent each second. The actual obserced speed may be lower if the producer is unable to work fast enough. If this is zero or unset, the producer will send as fast as possible.
seed	uint32	The seed value for a simple multiplicative congruential pseudo-random number sequence.
message_size	uint32	The size of each message in bytes. Should be greater than or equal 5 to account for the number of bytes needed to encode the random number and a null byte for the string.

TraceConfig.BuiltinDataSource

Config for disabling builtin data sources in the tracing service.

Defined in trace_config.proto

Fields:

Field	Type	Description
disable_clock_snapshotting	bool	Disable emitting clock timestamps into the trace.
disable_trace_config	bool	Disable echoing the original trace config in the trace.
disable_system_info	bool	Disable emitting system info (build fingerprint, cpuinfo, etc).
disable_service_events	bool	Disable emitting events for data-source state changes (e.g. the marker for all data sources having ACKed the start of the trace).
primary_trace_clock	BuiltinClock	The authoritative clock domain for the trace. Defaults to BOOTTIME. See also ClockSnapshot's primary_trace_clock. The configured value is written into the trace as part of the ClockSnapshots emitted by the service. Trace processor will attempt to translate packet/event timestamps from various data sources (and their chosen clock domains) to this domain during import. Added in Android R.
snapshot_interval_ms	uint32	Time interval in between snapshotting of sync markers, clock snapshots, stats, and other periodic service-emitted events. Note that the service only keeps track of the first and the most recent snapshot until ReadBuffers() is called.
prefer_suspend_clock_for_snapshot	bool	Hints to the service that a suspend-aware (i.e. counting time in suspend) clock should be used for periodic snapshots of service-emitted events. This means, if a snapshot should have happened during suspend, it will happen immediately after the device resumes. Choosing a clock like this is done on best-effort basis; not all platforms (e.g. Windows) expose a clock which can be used for periodic tasks counting suspend. If such a clock is not available, the service falls back to the best-available alternative. Introduced in Android S. crashes in S.

TraceConfig.ProducerConfig

Defined in trace_config.proto

Fields:

Field	Type	Description
producer_name	string	Identifies the producer for which this config is for.
shm_size_kb	uint32	Specifies the preferred size of the shared memory buffer. If the size is larger than the max size, the max will be used. If it is smaller than the page size or doesn't fit pages evenly into it, it will fall back to the size specified by the producer or finally the default shared memory size.
page_size_kb	uint32	Specifies the preferred size of each page in the shared memory buffer. Must be an integer multiple of 4K.

TraceConfig.StatsdMetadata

Contains statsd-specific metadata about an alert associated with the trace.

Defined in trace_config.proto

Fields:

Field	Type	Description
triggering_alert_id	int64	The identifier of the alert which triggered this trace.
triggering_config_uid	int32	The uid which registered the triggering configuration with statsd.
triggering_config_id	int64	The identifier of the config which triggered the alert.
triggering_subscription_id	int64	The identifier of the subscription which triggered this trace.

TraceConfig.GuardrailOverrides

Contains flags which override the default values of the guardrails inside Perfetto.

Defined in trace_config.proto

Fields:

Field	Type	Description
max_upload_per_day_bytes	uint64	Override the default limit (in bytes) for uploading data to server within a 24 hour period. On R-, this override only affected userdebug builds. Since S, it also affects user builds.

TraceConfig.TriggerConfig

Triggers allow producers to start or stop the tracing session when an event occurs.

For example if we are tracing probabilistically, most traces will be uninteresting. Triggers allow us to keep only the interesting ones such as those traces during which the device temperature reached a certain threshold. In this case the producer can activate a trigger to keep (STOP_TRACING) the trace, otherwise it can also begin a trace (START_TRACING) because it knows something is about to happen.

Defined in trace_config.proto

Fields:

Field	Type	Description
trigger_mode	TriggerMode
triggers	Trigger[]	A list of triggers which are related to this configuration. If ANY trigger is seen then an action will be performed based on `trigger_mode`.
trigger_timeout_ms	uint32	Required and must be positive if a TriggerConfig is specified. This is how long this TraceConfig should wait for a trigger to arrive. After this period of time if no trigger is seen the TracingSession will be cleaned up.

TraceConfig.TriggerConfig.TriggerMode

Defined in trace_config.proto

Enum values:

Name	Value	Description
UNSPECIFIED	0
START_TRACING	1	When this mode is chosen, data sources are not started until one of the `triggers` are received. This supports early initialization and fast starting of the tracing system. On triggering, the session will then record for `stop_delay_ms`. However if no trigger is seen after `trigger_timeout_ms` the session will be stopped and no data will be returned.
STOP_TRACING	2	When this mode is chosen, the session will be started via the normal EnableTracing() & StartTracing(). If no trigger is ever seen the session will be stopped after `trigger_timeout_ms` and no data will be returned. However if triggered the trace will stop after `stop_delay_ms` and any data in the buffer will be returned to the consumer.

TraceConfig.TriggerConfig.Trigger

Defined in trace_config.proto

Fields:

Field	Type	Description
name	string	The producer must specify this name to activate the trigger.
producer_name_regex	string	An std::regex that will match the producer that can activate this trigger. This is optional. If unset any producers can activate this trigger.
stop_delay_ms	uint32	After a trigger is received either in START_TRACING or STOP_TRACING mode then the trace will end `stop_delay_ms` after triggering.
max_per_24_h	uint32	Limits the number of traces this trigger can start/stop in a rolling 24 hour window. If this field is unset or zero, no limit is applied and activiation of this trigger always starts/stops the trace.
skip_probability	double	A value between 0 and 1 which encodes the probability of skipping a trigger with this name. This is useful for reducing the probability of high-frequency triggers from dominating trace finaization. If this field is unset or zero, the trigger will never be skipped. If this field is greater than or equal to 1, this trigger will always be skipped i.e. it will be as if this trigger was never included in the first place. This probability check is applied before any other limits. For example, if `max_per_24_h` is also set, first we will check if the probability bar is met and only then will we check the `max_per_24_h` limit.

TraceConfig.IncrementalStateConfig

Configuration for trace contents that reference earlier trace data. For example, a data source might intern strings, and emit packets containing {interned id : string} pairs. Future packets from that data source can then use the interned ids instead of duplicating the raw string contents. The trace parser will then need to use that interning table to fully interpret the rest of the trace.

Defined in trace_config.proto

Fields:

Field	Type	Description
clear_period_ms	uint32	If nonzero, notify eligible data sources to clear their incremental state periodically, with the given period. The notification is sent only to data sources that have `handles_incremental_state_clear` set in their DataSourceDescriptor. The notification requests that the data source stops referring to past trace contents. This is particularly useful when tracing in ring buffer mode, where it is not exceptional to overwrite old trace data. Warning: this time-based global clearing is likely to be removed in the future, to be replaced with a smarter way of sending the notifications only when necessary.

TraceConfig.CompressionType

Compress trace with the given method. Best effort.

Defined in trace_config.proto

Enum values:

Name	Value	Description
COMPRESSION_TYPE_UNSPECIFIED	0
COMPRESSION_TYPE_DEFLATE	1

TraceConfig.IncidentReportConfig

Android-only. Not for general use. If set, saves the trace into an incident. This field is read by perfetto_cmd, rather than the tracing service. This field must be set when passing the --upload flag to perfetto_cmd.

Defined in trace_config.proto

Fields:

Field	Type	Description
destination_package	string
destination_class	string
privacy_level	int32	Level of filtering in the requested incident. See `Destination` in frameworks/base/core/proto/android/privacy.proto.
skip_incidentd	bool	If true, then skips saving the trace to incidentd. This flag is useful in testing (e.g. Perfetto-statsd integration tests) or when we explicitly don't want traces to go to incidentd even when they usually would (e.g. configs deployed using statsd but only used for inclusion in bugreports using `bugreport_score`). The motivation for having this flag, instead of just not setting `incident_report_config`, is prevent accidents where `incident_report_config` is omitted by mistake.
skip_dropbox	bool	If true, do not write the trace into dropbox (i.e. incident only). Otherwise, write to both dropbox and incident.

TraceConfig.StatsdLogging

Defined in trace_config.proto

Enum values:

Name	Value	Description
STATSD_LOGGING_UNSPECIFIED	0
STATSD_LOGGING_ENABLED	1
STATSD_LOGGING_DISABLED	2

TraceConfig.TraceFilter

When set applies a post-filter to the trace contents using the filter provided. The filter is applied at ReadBuffers() time and works both in the case of IPC readback and write_into_file. This filter can be generated using tools/proto_filter -s schema.proto -F filter_out.bytes or -T filter_out.escaped_string (for .pbtx). See go/trace-filtering for design.

Introduced in Android S, but it was broken (b/195065199). Reintroduced in Android T with a different field number.

bytecode	bytes

TraceConfig.AndroidReportConfig

Android-only. Not for general use. If set, reports the trace to the Android framework. This field is read by perfetto_cmd, rather than the tracing service. This field must be set when passing the --upload flag to perfetto_cmd.

Defined in trace_config.proto

Fields:

Field	Type	Description
reporter_service_package	string
reporter_service_class	string
skip_report	bool	If true, then skips reporting the trace to Android framework. This flag is useful in testing (e.g. Perfetto-statsd integration tests) or when we explicitly don't want to report traces to the framework even when they usually would (e.g. configs deployed using statsd but only used for inclusion in bugreports using `bugreport_score`). The motivation for having this flag, instead of just not setting `framework_report_config`, is prevent accidents where `framework_report_config` is omitted by mistake.
use_pipe_in_framework_for_testing	bool	If true, will direct the Android framework to read the data in trace file and pass it to the reporter class over a pipe instead of passing the file descriptor directly. This flag is needed because the Android test framework does not currently support priv-app helper apps (in terms of SELinux) and we really don't want to add an allow rule for untrusted_app to receive trace fds. Because of this, we instead will direct the framework to create a new pipe and pass this to the reporter process instead. As the pipe is created by the framework, we won't have any problems with SELinux (system_server is already allowed to pass pipe fds, even to untrusted apps). As the name suggests this option MUST only be used for testing. Note that the framework will reject (and drop) files which are too large both for simplicity and to be minimize the amount of data we pass to a non-priv app (note that the framework will still check manifest permissions even though SELinux permissions are worked around).

TraceConfig.CmdTraceStartDelay

If set, delays the start of tracing by a random duration. The duration is chosen from a uniform distribution between the specified minimum and maximum. Note: this delay is implemented by perfetto_cmd not by traced so will not work if you communicate with traced directly over the consumer API. Introduced in Android T.

Defined in trace_config.proto

Fields:

Field	Type	Description
min_delay_ms	uint32
max_delay_ms	uint32
