class PerformanceNodeTiming
This property is an extension by Node.js. It is not available in Web browsers.
Provides timing details for Node.js itself. The constructor of this class is not exposed to users.
Properties #
#bootstrapComplete: number The high resolution millisecond timestamp at which the Node.js process completed bootstrapping. If bootstrapping has not yet finished, the property has the value of -1.
#environment: number The high resolution millisecond timestamp at which the Node.js environment was initialized.
The high resolution millisecond timestamp of the amount of time the event loop
has been idle within the event loop's event provider (e.g. epoll_wait). This
does not take CPU usage into consideration. If the event loop has not yet
started (e.g., in the first tick of the main script), the property has the
value of 0.
The high resolution millisecond timestamp at which the Node.js event loop
exited. If the event loop has not yet exited, the property has the value of -1.
It can only have a value of not -1 in a handler of the 'exit' event.
The high resolution millisecond timestamp at which the Node.js event loop started. If the event loop has not yet started (e.g., in the first tick of the main script), the property has the value of -1.
The high resolution millisecond timestamp at which the Node.js process was initialized.
#uvMetricsInfo: UVMetrics This is a wrapper to the uv_metrics_info function.
It returns the current set of event loop metrics.
It is recommended to use this property inside a function whose execution was
scheduled using setImmediate to avoid collecting metrics before finishing all
operations scheduled during the current loop iteration.
