cpu-percentage

Get CPU usage percentage of own process

• Uses JavaScript only and node API (process.cpuUsage).
• No native code.
• No external processes.

Note: requires node 6.1 or later.

See also cpu-gauge.

Install

npm install -S cpu-percentage

Usage

In this example we measure the CPU usage while loading a text file.

var usage = require('cpu-percentage');
var fs = require('fs');
 
var start = usage();
fs.readFile(__filename, 'utf8', function(err, data) {
  console.log(usage(start));
});

The result is similar to

{ user: 8000, system: 4000, time: 9, percent: 133.33333333333334 }
