cpu-gauge

Simple CPU usage metering for node

Wraps process.cpuUsage()
in a simple to use interface.
No need to multiply and divide to get CPU usage percentage.

Note: requires Node.js 6.1 or later.

Install

``sh
npm install --save cpu-gauge
`

Usage

`js
const gauge = require('cpu-gauge');

var cpu = gauge.start();
// ...
console.log(cpu.usage().percent);
`

Note altough node executes JavaScript in a single thread, it uses additional
threads for background tasks. So it is possible that CPU goes well above 100%.

API

$3

Starts metering the CPU usage.
Returns a _cpu_ object.

$3

Resturns CPU usage of current process since _start()_ invocation.
Returned object has the following properties:
* user - user CPU time in microseconds
* system - system CPU time in microseconds
* time - elapsed time in microseconds
* percent` - CPU usage as percent of a logical core, so it could be above 100
