Node.js process.resourceUsage() Function

The process object is a global that provides information about, and control over, the current Node.js process. As a global, it is always available to Node.js applications without using require(). It can also be explicitly accessed using require() function.

process.resourceUsage() is a new method that returns resource usage for the current process.

Syntax:

process.resourceUsage()

Parameters: This function does not accept any parameter.

Return Value: It returns the resource usage for the current process. All of these values come from the uv_getrusage call which returns a uv_rusage_t struct.

Below examples illustrate the use of the process.resourceUsage() property in Node.js:

Example:

index.js

// Node.js program to demonstrate the
// process.resourceUsage() Property
