System Information

A toolkit for gathering system information using Python.

When to Use This Skill

Activate this skill when the user needs to:

• Check CPU usage and information
• Monitor memory usage
• View disk space and partitions
• List running processes
• Diagnose system performance issues

Requirements

For full functionality, install psutil:

pip install psutil

Scripts will gracefully degrade to use standard library methods if psutil is not available.

Available Scripts

Always run scripts with --help first to see all available options.

Script	Purpose
cpu_info.py	CPU usage and information
memory_info.py	Memory usage statistics
disk_info.py	Disk usage and partitions
process_list.py	List running processes

Decision Tree

Task → What do you need?
    │
    ├─ CPU information/usage?
    │   └─ Use: cpu_info.py
    │
    ├─ Memory usage?
    │   └─ Use: memory_info.py
    │
    ├─ Disk space?
    │   └─ Use: disk_info.py
    │
    └─ Process information?
        └─ Use: process_list.py

Quick Examples

CPU information:

python scripts/cpu_info.py
python scripts/cpu_info.py --watch 2  # Update every 2 seconds

Memory usage:

python scripts/memory_info.py
python scripts/memory_info.py --human

Disk information:

python scripts/disk_info.py
python scripts/disk_info.py --all  # Include all filesystems

Process list:

python scripts/process_list.py
python scripts/process_list.py --sort cpu
python scripts/process_list.py --filter python

Common Use Cases

1. Check if system is overloaded: cpu_info.py + memory_info.py
2. Find memory-hungry processes: process_list.py --sort memory
3. Check available disk space: disk_info.py
4. Find process by name: process_list.py --filter nginx
5. Monitor system in real-time: cpu_info.py --watch 1

Output Formats

Most scripts support:

• Human-readable (default): Formatted output with units
• JSON (--json): Machine-readable JSON format
• Compact (--compact): Minimal output

Platform Notes

• Linux: Full functionality
• macOS: Most features work, some Linux-specific info unavailable
• Windows: Basic functionality, some features may differ

Notes

• Scripts attempt to use psutil for accurate information
• Without psutil, fallback to /proc filesystem (Linux) or system commands
• Resource monitoring may require appropriate permissions
• Watch mode (--watch) runs until interrupted with Ctrl+C
