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

• Check if system is overloaded: cpu_info.py

• memory_info.py

• Find memory-hungry processes: process_list.py --sort memory

• Check available disk space: disk_info.py

• Find process by name: process_list.py --filter nginx

• 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
