Functions

createHistogram

external fun createHistogram(options: CreateHistogramOptions = definedExternally): RecordableHistogram

Returns a {@link RecordableHistogram RecordableHistogram}.

eventLoopUtilization

external fun eventLoopUtilization(utilization1: EventLoopUtilization = definedExternally, utilization2: EventLoopUtilization = definedExternally): EventLoopUtilization

The eventLoopUtilization() function returns an object that contains the cumulative duration of time the event loop has been both idle and active as a high resolution milliseconds timer. The utilization value is the calculated Event Loop Utilization (ELU).

monitorEventLoopDelay

external fun monitorEventLoopDelay(options: EventLoopMonitorOptions = definedExternally): IntervalHistogram

This property is an extension by Node.js. It is not available in Web browsers.

external fun <T : Function<Any?>> timerify(fn: T, options: TimerifyOptions = definedExternally): T

This property is an extension by Node.js. It is not available in Web browsers.
