Node.js Metrics Dashboard & Tracker

This project consists of two main parts: a Dashboard and a Tracker.

• Dashboard: A Next.js server that visualizes Node.js metrics.
• Tracker: A reusable package that sends Node.js metrics to the Dashboard.

---

Dashboard

The dashboard is a Next.js server that runs on port 9090 and exposes APIs to collect metrics.

Setup

1. Navigate to the dashboard folder:

   cd dashboard

2. Install dependencies:

   npm install

3. Start the development server:

   npm run dev

4. The server will be accessible at: http://localhost:9090

Tracker

The tracker is a Node.js package that can be installed in any project to send metrics to the dashboard.

Setup

1. Move the tracker package(tracker-1.0.0.tgz) to the root of the project you want to monitor. For example, if your project runs on localhost:3000:

2. Install the package:

   npm install ./tracker-1.0.0.tgz

3. Import and activate the tracker in your project. For example, in your Next.js layout.tsx:

   import { activateMetrics } from "tracker";
   
   activateMetrics();

4. Once activated, metrics from this project will be sent to the dashboard for visualization:

   Important: Do not call activateMetrics in client-side code, as it only works in Node.js.

Note:
This is a test prototype. Currently, it uses setTimeout for sending metrics, but in the future it will be replaced with a proper socket server.
The dashboard uses Chart.js ("chart.js": "^4.5.1") — special thanks to this cool library!
This project is mainly for learning purposes.
