The Hardware Monitor project is a lightweight Go-based system that provides real-time monitoring of a computer's hardware metrics, including CPU, memory, and disk usage. The information is displayed on a web interface that is updated dynamically using WebSockets.

• System Information Monitoring: Captures and displays system information such as hostname, total and used memory, operating system, disk space, and CPU details.
• Real-time Updates: Utilizes WebSockets to push hardware metrics to the frontend in real-time.
• Responsive UI: A user-friendly and responsive web interface designed with modern CSS practices.
• Templating: Custom Go templates are used to render hardware data into HTML.

• Go 1.16+ installed
• Git for version control
• Access to the terminal/command prompt

1. Clone the repository:

   git clone https://github.com/your-username/hardware-monitor-go.git
   cd hardware-monitor-go

2. Install dependencies:

   go mod tidy

3. Build the project:

   make build

4. Run the project:

   make run

   The server will start on http://localhost:8080.

• Web Interface: Open your web browser and navigate to http://localhost:8080. The page will display real-time hardware metrics.
• Customizing the UI: Modify static/styles.css to customize the look and feel of the interface.
• Extend the Metrics: Add additional metrics by editing internal/hardware/hardware.go and corresponding Go template files.

Run the tests with:

make test

The tests cover the server components and ensure the correct functionality of WebSocket communication and hardware data retrieval.

• Add support for monitoring GPU usage.
• Implement user authentication for accessing the monitoring page.
• Enhance error handling and logging.
