lup-system

Node module that provides utilities for interacting with the operating system and the hardware of the machine.

Example

JavaScript:

const lupSystem = require('lup-system');

lupSystem.getCpuInfo().then(cpuInfo => console.log("CPU Info: " + cpuInfo));
lupSystem.getDrives().then(drives => console.log("Drives: " + drives)); // Array of drive objects
lupSystem.getGPUs().then(gpus => console.log("GPU Info: " + gpus));
lupSystem.getMemoryInfo().then(memoryInfo => console.log("Memory Info: " + memoryInfo));
lupSystem.getNetworkInterfaces().then(interfaces => console.log("Network Interfaces: " + interfaces));
lupSystem.getOSInfo().then(osInfo => console.log("OS Info: " + osInfo));
lupSystem.getTemperatures().then(temps => console.log("Temperatures: " + temps));

TypeScript:

import lupSystem from 'lup-system';

(async () => {
    console.log("CPU Info: ", await lupSystem.getCpuInfo());
    console.log("Drives: ", await lupSystem.getDrives()); // Array of drive objects
    console.log("GPU Info: ", await lupSystem.getGPUs());
    console.log("Memory Info: ", await lupSystem.getMemoryInfo());
    console.log("Network Interfaces: ", await lupSystem.getNetworkInterfaces());
    console.log("OS Info: ", await lupSystem.getOSInfo());
    console.log("Temperatures: ", await lupSystem.getTemperatures());
})();

GPU Readings

For more detailed information on GPUs it is recommended to install the nvidia-smi tool. For GPU core count and flops calculations install nvidia-settings e.g. using apt install -y nvidia-settings.
