Public Methods
void RingBufferRecorder (RingBufferSpecification * ring_buffer_spec, inspect::Node node, const zx::time & created_at)Defined at line 265 of file ../../src/media/audio/drivers/lib/inspect/recorder.cc
void RecordDestructionTime (const zx::time & destroyed_at)Defined at line 272 of file ../../src/media/audio/drivers/lib/inspect/recorder.cc
void RecordStartTime (const zx::time & started_at)This captures the current startup_task_save_count_ and final_task_save_count_ for this interval.
Defined at line 277 of file ../../src/media/audio/drivers/lib/inspect/recorder.cc
void RecordStopTime (const zx::time & stopped_at)Defined at line 293 of file ../../src/media/audio/drivers/lib/inspect/recorder.cc
void SaveStartupAndFinalTaskMetrics (size_t startup_task_save_count, size_t final_task_save_count)Set the values that are captured into a RunningInterval at creation (upon RecordStartTime call).
Can be called multiple times; does not affect a currently-active RunningInterval.

void RecordTaskMetrics (const Subtask::Metrics & metrics)Defined at line 308 of file ../../src/media/audio/drivers/lib/inspect/recorder.cc
void RecordTaskUnderrun (int64_t underrun_frames)Defined at line 328 of file ../../src/media/audio/drivers/lib/inspect/recorder.cc
void RecordTaskOverrun (int64_t overrun_frames)Defined at line 335 of file ../../src/media/audio/drivers/lib/inspect/recorder.cc
void RecordDroppedTransfer ()Defined at line 342 of file ../../src/media/audio/drivers/lib/inspect/recorder.cc
void RecordActiveChannelsCall (uint64_t active_channels_bitmask, const zx::time & set_active_channels_called_at, const zx::time & active_channels_completed_at)Defined at line 349 of file ../../src/media/audio/drivers/lib/inspect/recorder.cc
void SetupBufferTracker (const std::string & name, std::optional<uint32_t> max_buffer_count, std::optional<zx::duration> per_buffer_duration)On some platforms, the ring buffer might be fed into hardware buffers. These methods enable
tracking of metrics associated with such hardware buffers.

void RecordBufferSubmission ()Defined at line 373 of file ../../src/media/audio/drivers/lib/inspect/recorder.cc
void RecordBufferCompletion ()Defined at line 379 of file ../../src/media/audio/drivers/lib/inspect/recorder.cc
void SetTaskScheduleInterval (zx::duration interval)Sets the expected interval between tasks. This is used to calculate
scheduling delay metrics.
