Member Function Documentation

◆ CollectSample()

void CollectSample ( )

Force collection of a sample. Must be called on the VM thread. Recording the forced sample does not contribute to the aggregated profile statistics.

◆ SetIdle()

void SetIdle ( bool is_idle )

Tells the profiler whether the embedder is idle.

◆ SetSamplingInterval()

void SetSamplingInterval ( int us )

Changes default CPU profiler sampling interval to the specified number of microseconds. Default interval is 1000us. This method must be called when there are no profiles being recorded.

◆ StartProfiling()

void StartProfiling	(	Local< String >	title,
		bool	record_samples = `false`
	)

Starts collecting CPU profile. Title may be an empty string. It is allowed to have several profiles being collected at once. Attempts to start collecting several profiles with the same title are silently ignored. While collecting a profile, functions from all security contexts are included in it. The token-based filtering is only performed when querying for a profile.

|record_samples| parameter controls whether individual samples should be recorded in addition to the aggregated tree.

◆ StopProfiling()

CpuProfile* StopProfiling ( Local< String > title )

Stops collecting CPU profile with a given title and returns it. If the title given is empty, finishes the last profile started.
