'desktop' AS client,
COUNT(0) AS volume,
AVG((bytesTotal / 1024) / (fullyLoaded / 1000)) as mean,
NTH(101, QUANTILES((bytesTotal / 1024) / (fullyLoaded / 1000), 1001)) AS q_10th,

Getting CPU(s) usage % with NodeJS,based on: https://github.com/oscmejia/os-utils/blob/master/lib/osutils.js
var os = require('os');
const RESOLUTION = 1000; // 1s CPU resolution
function cpusInfo() {
return os.cpus().map(function(cpu) {
var t = cpu.times;
