System Monitor

A Node.js application that provides real-time system monitoring capabilities, displaying various system metrics and CPU usage statistics.

Features

• System Information Display

  • CPU cores count
  • Total memory (GB)
  • Free memory (MB)
  • System uptime (hours)
  • Platform information
  • System architecture

• CPU Monitoring

  • Real-time CPU usage monitoring per core
  • Updates every second
  • Displays results in a clear table format
  • Calculates percentage usage for each CPU core

Installation

npm install

Usage

Run the application using:

node index.js

The application will start displaying system information and continuously monitor CPU usage per core in a table format.

Requirements

• Node.js
• node:os module (built-in)

How It Works

The application uses Node.js's built-in os module to:

1. Gather initial system information
2. Calculate CPU usage by comparing measurements over time
3. Display real-time updates in a formatted table

Output Example

The application displays a table showing:

• Core number
• CPU usage percentage for each core

System information is shown at startup, followed by continuous CPU usage updates.
