Package Exports

js-monitor-server
js-monitor-server/index.js

This package does not declare an exports field, so the exports above have been automatically detected and optimized by JSPM instead. If any package subpath is missing, it is recommended to post an issue to the original package (js-monitor-server) to support the "exports" field. If that is not possible, create a JSPM override to customize the exports field for this package.

Features

Real-time monitoring of CPU usage and memory consumption
Web-based UI for easy visualization
Customizable monitoring interval
WebSocket communication for live updates

Prerequisites

Node.js (version 12 or higher recommended)
npm (Node Package Manager)

Installation

Install the js-monitor-server as dependency of your application:
```
npm install js-monitor-server@latest
```

Usage

Import the library as dependency of your ESM nodejs app.
```
import 'js-monitor-server';
```
For common js modules, use dynamic import:
```
import('js-monitor-server');
```
The default web server port is 9966. You can change it by changing the MONITOR_PORT environment variable in the .env file.
Open a web browser and navigate to http://localhost:9966 (or the port specified in your environment variables).
The UI will display real-time CPU and memory usage of the monitored process.

File Structure

index.js: Entry point of the application
server.js: Sets up the Express server and Socket.io
monitor.js: Contains the Monitor class for tracking system resources
public/index.html: The frontend UI for displaying monitoring data

How It Works

The Monitor class in monitor.js uses Node.js's process.cpuUsage() and process.memoryUsage() to collect system resource data.
The Express server in server.js serves the frontend and sets up WebSocket communication using Socket.io.
The frontend (index.html) receives real-time updates via WebSocket and displays the data using charts (implementation not shown in the provided code).
