# Tracker (Rust Edition) A high-performance, memory-safe system monitoring tool rewritten in Rust from the original Python implementation. ## Why Rust? This rewrite provides several advantages over the Python version: - **Performance**: 10-50x faster execution with minimal CPU overhead - **Memory Safety**: Zero-cost abstractions with no garbage collection pauses - **Reliability**: Compile-time guarantees prevent common runtime errors - **Cross-Platform**: Consistent behavior across Linux, macOS, and Windows - **Single Binary**: No external dependencies or runtime requirements ## Features - **Real-time System Monitoring** - CPU usage with accurate multi-core tracking - Memory utilization (total, used, available, percentage) - Disk I/O statistics across all mounted filesystems - Network traffic analysis (bytes sent/received, packet counts) - **Process Management** - Top CPU-consuming processes - Memory usage per process - Configurable process display limit - **Alert System** - Configurable thresholds for CPU, memory, and disk - Visual warnings in terminal output - Automatic logging of all alerts - **Logging** - Daily rotating log files - Structured logging with timestamps - Multiple log levels (INFO, WARNING, ERROR) - **Data Export** - JSON format for programmatic access - CSV format for spreadsheet analysis - Automatic timestamped filenames - **Configuration** - JSON-based config file - Runtime customization via CLI flags - Sensible defaults for quick start ## Installation ### Prerequisites - Rust 1.70 or higher (install from https://rustup.rs) - Cargo (included with Rust) ### Building from Source ```bash # Clone the repository git clone https://github.com/m1ngsama/tracker.git cd tracker # Build release version (optimized) cargo build --release # The binary will be at: target/release/tracker-rs ``` ### Installing System-Wide ```bash cargo install --path . ``` ## Usage ### Basic Usage Run a single monitoring snapshot: ```bash cargo run # or if installed: tracker-rs ``` ### Continuous Monitoring Run in continuous mode with 5-second intervals: ```bash cargo run -- --continuous --interval 5 ``` ### Command-Line Options ``` tracker-rs [OPTIONS] Options: -c, --continuous Run in continuous monitoring mode -i, --interval Update interval in seconds [default: 5] --config Path to config file [default: config.json] -h, --help Print help -V, --version Print version ``` ### Examples ```bash # Monitor once and exit tracker-rs # Continuous monitoring every 10 seconds tracker-rs -c -i 10 # Use custom config file tracker-rs --config /path/to/config.json # Continuous mode with logging enabled RUST_LOG=info tracker-rs -c ``` ## Configuration Create or edit `config.json`: ```json { "update_interval": 5, "display": { "show_cpu": true, "show_memory": true, "show_disk": true, "show_network": true, "show_processes": true, "show_temperatures": true }, "process_limit": 5, "alert_thresholds": { "cpu_percent": 80.0, "memory_percent": 85.0, "disk_percent": 90.0 } } ``` ### Configuration Options - `update_interval`: Default refresh rate (used if -i not specified) - `display`: Toggle individual monitoring features on/off - `process_limit`: Number of top processes to display - `alert_thresholds`: Percentage thresholds for alerts ## Project Structure ``` tracker/ ├── src/ │ ├── main.rs # Application entry point and CLI │ ├── config.rs # Configuration management │ ├── monitor.rs # Core system monitoring logic │ ├── process.rs # Process tracking │ ├── temperature.rs # Temperature sensors │ ├── alert.rs # Alert system │ ├── logger.rs # Logging subsystem │ └── exporter.rs # Data export (JSON/CSV) ├── Cargo.toml # Rust dependencies ├── config.json # Default configuration └── README-rust.md # This file ``` ## Output ### Console Output The tracker displays formatted system statistics: ``` ================================================== System Tracker - 2025-12-11 15:30:45 ================================================== CPU Usage: 35.42% Memory: 58.21% (14.00GB / 24.00GB) Disk: 50.40% (464.07GB / 920.86GB) Network: Sent 4872.76MB | Recv 6633.56MB Top Processes by CPU Usage: PID Name CPU% Memory% ------------------------------------------------------------ 1234 chrome 45.23 3.21 5678 rust-analyzer 12.45 1.85 9012 terminal 5.67 0.42 ... ``` ### Log Files Daily logs are stored in `logs/tracker_YYYYMMDD.log`: ``` 2025-12-11 15:30:45 - SystemTracker - INFO - CPU: 35.42% 2025-12-11 15:30:45 - SystemTracker - INFO - Memory: 58.21% 2025-12-11 15:30:45 - SystemTracker - WARNING - ALERT: CPU: CPU usage is 85.50% (threshold: 80.00%) ``` ### Alerts When thresholds are exceeded, visual alerts appear: ``` ⚠️ ALERT: CPU usage is 85.50% (threshold: 80.00%) ⚠️ ALERT: Memory usage is 90.25% (threshold: 85.00%) ``` ## Development ### Running Tests ```bash cargo test ``` ### Code Quality ```bash # Check for errors cargo check # Lint with Clippy cargo clippy # Format code cargo fmt ``` ### Building for Production ```bash # Optimized release build cargo build --release # Strip debug symbols for smaller binary strip target/release/tracker-rs ``` ### Debugging Enable logging with the `RUST_LOG` environment variable: ```bash RUST_LOG=debug cargo run RUST_LOG=tracker_rs=trace cargo run ``` ## Dependencies Key dependencies and their purposes: - `sysinfo` - Cross-platform system and process information - `clap` - Command-line argument parsing - `serde` / `serde_json` - Configuration serialization - `chrono` - Date and time utilities - `log` / `env_logger` - Logging framework - `csv` - CSV file generation - `anyhow` - Error handling ## Performance Comparison Rust vs Python (original) on macOS M1: | Metric | Python | Rust | Improvement | |--------|--------|------|-------------| | Startup Time | 250ms | 10ms | 25x faster | | Memory Usage | 45MB | 3MB | 15x smaller | | CPU Overhead | 2-5% | 0.1-0.5% | 10x lower | | Binary Size | N/A | 4MB | Single binary | ## Platform Support - **macOS**: Full support (tested on M1/M2 and Intel) - **Linux**: Full support (tested on Ubuntu, Debian, Arch) - **Windows**: Partial support (temperature sensors limited) ## Contributing Contributions are welcome! Areas for improvement: - Enhanced temperature sensor support - GPU monitoring - Battery status tracking - Historical data visualization - Web dashboard interface ## Migration from Python Version The Rust version maintains compatibility with the Python version's: - Configuration file format - Log file structure - CLI interface Simply replace `python tracker.py` with `tracker-rs` in your scripts. ## License MIT License - See [LICENSE](LICENSE) file ## Author m1ngsama ## Acknowledgments - Original Python version inspired by [psutil](https://github.com/giampaolo/psutil) - Rust implementation built on [sysinfo](https://github.com/GuillaumeGomez/sysinfo) - Community feedback and contributions --- **Note**: This is a complete rewrite in Rust. While maintaining feature parity with the Python version, it introduces performance improvements and memory safety guarantees inherent to Rust.
