BytesCrafter / nodejs-cpu-percent.js
Created April 28, 2020 06:36
Convert the output of os.cpus() in Node.js to percentage
// According to the http://nodejs.org/docs/latest/api/os.html#os_os_cpus, times is
// an object containing the number of CPU ticks spent in: user, nice, sys, idle, and irq
// So you should just be able to sum the times and calculate the percentage, like below:
var cpus = os.cpus();
for(var i = 0, len = cpus.length; i < len; i++) {
console.log("CPU %s:", i);
var cpu = cpus[i], total = 0;
