A real-time network monitoring application for macOS that provides comprehensive visual analysis of network connectivity through continuous ICMP ping operations.

PingGraph delivers enterprise-level network monitoring with millisecond precision timing, intelligent performance optimization, and advanced visualization capabilities. Monitor up to 8 concurrent network targets with hardware-accelerated charts maintaining smooth 60fps performance even with large datasets.

• Real-time Network Monitoring: Continuous ICMP ping operations with millisecond precision
• Multi-target Support: Monitor up to 8 network targets simultaneously
• Advanced Visualization: Hardware-accelerated charts with intelligent performance optimization
• Comprehensive Statistics: Detailed analysis including packet loss, jitter, and quality metrics
• Smart Data Management: Three-tier storage system with automatic compression
• Export Capabilities: Multiple formats (CSV, JSON, XML) with flexible data selection
• Native macOS Interface: SwiftUI-based with dark theme and keyboard shortcuts

• macOS 13.0 or later
• Xcode 15.0+ (for building from source)
• Administrator privileges (required for ICMP operations)

1. Clone the repository:

   git clone https://github.com/yourusername/pinggraph.git
   cd pinggraph

2. Open in Xcode:

   open pinggraph.xcodeproj

3. Build and run:

   • Select "pinggraph" scheme
   • Press ⌘+R to build and run
   • Grant ICMP privileges when prompted

1. Add a target: Enter an IP address or hostname (e.g., 8.8.8.8 or google.com)
2. Start monitoring: Click "Start" or press ⌘+R
3. View real-time data: Watch live charts showing response times and packet loss
4. Manage multiple targets: Use ⌘+T to create new tabs
5. Export data: Use ⌘+E to export in various formats

• Multi-tab Interface: Up to 8 concurrent ping operations
• ICMP Network Engine: Raw socket implementation with privilege handling
• Three-tier Data Storage: Hot cache → Compact buffer → Compressed storage
• Performance Optimization: 4-tier adaptive rendering system
• Statistics Engine: Real-time network quality metrics

• Memory Efficient: 87% memory reduction through optimized data structures
• Hardware Accelerated: Metal-backed rendering for smooth performance
• Intelligent Sampling: Smart data reduction for large datasets
• Adaptive Optimization: Automatic performance tuning

Access via ⌘+,:

• Ping Interval: 0.1 to 10 seconds
• Timeout Duration: 1 to 30 seconds
• Data Retention: 10 minutes to 24 hours
• Performance Optimization: None/Light/Medium/Aggressive

• Target: IP address or hostname
• Custom Intervals: Override global settings
• IPv6 Support: Enable IPv6 connectivity testing

• ⌘+T: New tab
• ⌘+W: Close tab
• ⌘+D: Duplicate tab
• ⌘+,: Preferences

• ⌘+R: Start/Resume monitoring
• ⌘+S: Stop monitoring
• ⌘+Shift+R: Start all tabs

• ⌘+E: Export current tab
• ⌘+Shift+E: Export all tabs
• ⌘+I: Performance dashboard

• CSV: Comma-separated values for spreadsheet analysis
• JSON: Structured data for programmatic processing
• XML: Hierarchical format for enterprise integration

• Current Tab: Active monitoring session
• All Tabs: All monitoring sessions
• Date Range: Custom time windows
• Selected Data: Custom field selection

ICMP Permission Denied:

# Run with elevated privileges
sudo open /Applications/PingGraph.app

# Or configure in System Preferences:
# System Preferences > Security & Privacy > Privacy > Network

High Memory Usage:

• Reduce data retention period
• Enable aggressive optimization mode
• Close unused tabs

Poor Performance:

• Enable automatic optimization
• Reduce visible time range
• Lower ping frequency for long-term monitoring
