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.
npm install cpu-percentage
In this example we measure the CPU usage while loading a text file.
const usage = require('cpu-percentage');
const fs = require('fs');
const start = usage();
fs.readFile(__filename, 'utf8', (err, data) => {
console.log(usage(start));
});
The result is similar to
{ user: 8000, system: 4000, time: 9, percent: 133.33333333333334 }
