Node-System-Stats

Note: You can find documentation for all of the types and functions here.

Note: This module only relies on the os module, so it should be compatible on all OS's where Node.js runs.

Note: This package is a TS-rewrite of the old package cpu-stat. Also it comes with 1 more function to measure the ram usage. More functions will be added later.

Installing

npm install node-system-stats

Examples on how to use it

To measure the cpu Usage in percent, you can use this function below. Parameter Description can be found here

By default you can use it like that:

// TypeScript: import { usagePercent } from "node-system-stats";
const { usagePercent } = require("node-system-stats")

let result = { percent: 0 };

try {
    result = await usagePercent()
} catch (err) {
    console.log(err)
}

console.log(result); // Output: { percent: 1.5, seconds: 1}

Get the cpu usage percent for core 0 over a sample period of 2000ms:

// TypeScript: import { usagePercent } from "node-system-stats"
const { usagePercent } = require("node-system-stats");

let result = { percent: 0 };

try {
    result = await usagePercent({ coreIndex: 0, sampleMs: 2000 })
} catch (err) {
    console.log(err);
}

console.log(result);

To get all of the cores, you can use this function below. View here for more description.

// TypeScript: import { totalCores } from "node-system-stats"
const { totalCores } = require("node-system-stats");

console.log(totalCores); // Output: 8 
                           
// Note: Threads count as cores too! So if you want to only get the "real" cores use the code snippet below:
console.log(totalCores / 2); // Output: 4

If you want to get the Average CPU Clock speed, then use this function below. View here for more description.

// TypeScript: import { avgClockMHz } from "node-system-stats"
const { avgClockMHz } = require("node-system-stats");

console.log(avgClockMHz()); // Output: 3600

Note: To see every function, please take a look at the documentation.
