Rust-Dashboard

Rust-Dashboard is a cross-platform system monitoring dashboard built with sysinfo and eframe/egui.

Features

• Displays current CPU usage and memory usage in GiB
• Collects and shows disk usage and network usage (per interface)
• Lists top 5 processes by CPU and memory usage
• Supports an adjustable refresh interval
• Spawns a background thread to continuously refresh system data

Architecture

• system.rs: Contains the SystemMonitor struct which wraps sysinfo::System, plus extra methods for processing data (like combined processes).
• main.rs: The main entry point uses RustDashboardApp, which:
  • Spawns a background thread to refresh the system info
  • Renders a GUI using eframe/egui

How It Works

1. The main application spawns a background thread on startup.
2. This thread periodically locks the SystemMonitor and calls refresh().
3. The user interface is rendered in the main thread using egui, reading the latest data from the SystemMonitor.
4. Key stats are displayed:
   • CPU usage
   • Memory usage (used, free, total, available, swap)
   • Per-disk usage in GiB
   • Network usage for interfaces in use
   • Top processes by CPU and memory usage
5. The refresh interval for the background thread is set to 5 seconds by default, but the user can adjust the display refresh interval (which also triggers the UI to update).

Requirements

• Rust 1.60+ (2023 edition recommended)
• eframe = "0.31.1"
• sysinfo = "0.33.1"

Usage

1. Clone or download this repository.
2. In the Rust-Dashboard directory, run:

   cargo run

   This will compile and launch the dashboard.
3. Adjust the refresh interval from the top bar to change how frequently the UI fetches new data and repaints.
