options: Object – resolution: The sampling rate in milliseconds. Must be greater than zero. Default: 10.
Returns: Histogram
Creates a Histogram object that samples and reports the event loop delay over time. The delays will be reported in nanoseconds. Using a timer to detect approximate event loop delay works because the execution of timers is tied specifically to the lifecycle of the libuv event loop. That is, a delay in the loop will cause a delay in the execution of the timer, and those delays are specifically what this API is intended to detect.
