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

# 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

cargo install --path .

Usage

Basic Usage

Run a single monitoring snapshot:

cargo run
# or if installed:
tracker-rs

Continuous Monitoring

Run in continuous mode with 5-second intervals:

cargo run -- --continuous --interval 5

Command-Line Options

tracker-rs [OPTIONS]

Options:
  -c, --continuous           Run in continuous monitoring mode
  -i, --interval <SECONDS>   Update interval in seconds [default: 5]
      --config <FILE>        Path to config file [default: config.json]
  -h, --help                 Print help
  -V, --version              Print version

Examples

# 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:

{
  "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

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%)
