A desktop-based monitoring tool that provides real-time system health data, including CPU speed, memory usage, disk space, uptime, and network interface details. Built with Rust for the backend and HTML/Tera for the frontend, this project showcases low-level Windows API integration, system diagnostics, and web templating in a desktop environment. My motivation for this project was to gain familiarity with Windows API, the long term goal is to create a distributable windows application (using Windows UI).

The Computer Health Monitor is a lightweight Windows utility that displays basic hardware and system performance metrics in a browser-based interface.Leverages Windows API calls to deliver accurate system insights without third-party dependencies or bloat.

Key features:

• System uptime
• CPU clock speed
• Memory usage statistics
• Disk space usage
• Enumerated network interface list

• windows — access to Windows APIs (e.g., GetIfTable, GlobalMemoryStatusEx)
• actix-web — asynchronous web server framework
• tera — HTML templating engine (Jinja2-style)
• serde — data serialization/deserialization
• serde_json — JSON conversion (if needed for API endpoints)
• futures — async support for request handling

• HTML-based local webpage (rendered using Tera)

Browser (HTML interface) │ ▼ GET request to `/` (root route) │ ▼ Actix-web server (Rust) ├── Gathers system data: │ ├─ CPU speed │ ├─ Memory info │ ├─ Disk info │ └─ Network interfaces via Win32 APIs └── Renders HTML using Tera templates │ ▼ Renders system info in browser UI
