A cross-platform GUI network monitoring application built with Rust and egui that tracks network connectivity using ping commands. The application visualizes ping results in an intuitive clock-face format with color-coded status indicators.
- Clock-Face Visualization: 12 circles positioned at clock positions representing 5-second intervals over a 60-second cycle
- Color-Coded Status (configurable thresholds):
- 🟢 Green: Response time < 100ms (default)
- 🟡 Yellow: Response time 100-200ms (default)
- 🟠 Orange: Response time > 200ms (default)
- 🔴 Red: Failed ping
- ⚫ Gray: No data or expired (after 55 seconds)
- DNS Caching: Intelligent DNS resolution caching with 5-minute TTL to reduce network overhead
- Real-time Statistics: Success rate, loss rate, and mean response time
- Persistent Configuration: Automatically saves and loads ping target
- Cross-Platform: Works on Windows, macOS, and Linux
- Always-on-Top Window: Stays visible while working with other applications
- Rust 1.70+ (2024 edition)
- Cargo package manager
git clone <repository-url>
cd ping-monitor
cargo build --releasecargo run- Set Target: Enter the IP address or hostname you want to monitor (default: 8.8.8.8)
- Start Monitoring: Click the "Start" button to begin ping monitoring
- View Results:
- The clock face shows ping results for the last 60 seconds
- Each circle represents a 5-second interval
- Colors fade over time and turn gray after 55 seconds
- The red second hand shows the current position in the 60-second cycle
- Statistics: View real-time statistics including success rate, loss rate, and mean response time
- Frontend: egui/eframe for cross-platform GUI
- Ping Logic: surge-ping library for ICMP ping functionality
- DNS Resolution: Built-in DNS caching with configurable TTL
- Data Management: Rolling buffer of 60 ping results
- Configuration: JSON-based persistent storage
- macOS:
~/Library/Application Support/PingMonitor/config.json - Windows:
%APPDATA%/PingMonitor/config.json - Linux:
~/.config/PingMonitor/config.json
- Pings occur every 5 seconds at real-world boundaries (0, 5, 10, 15... seconds)
- DNS resolution is cached for 5 minutes to minimize network overhead
- Circle colors age over time with gradual fading
- Statistics are calculated from the last 60 seconds of data
- UI refreshes at 20 FPS for smooth animations
- Window is always-on-top and non-resizable (450x600)
- egui/eframe: GUI framework
- surge-ping: ICMP ping implementation
- chrono: Date and time handling
- serde/serde_json: Configuration serialization
- dirs: Platform-specific directory paths
- tokio: Async runtime (full features)
