PerformanceNodeTiming

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.

The total number of milliseconds elapsed for this entry. This value will not be meaningful for all Performance Entry types.

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 name of the performance entry.

The high resolution millisecond timestamp at which the Node.js process was initialized.

The high resolution millisecond timestamp marking the starting time of the Performance Entry.

This is a wrapper to the uv_metrics_info function. It returns the current set of event loop metrics.

The high resolution millisecond timestamp at which the V8 platform was initialized.
