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 -```bash -# Single run -cargo run +### Basic Usage -# Continuous monitoring +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 -Edit `config.json` to customize monitoring behavior and alert thresholds. +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 -
