Monitoring disk space using Python.

Python script to monitor disk space on Windows, Linux, and macOS involves using cross-platform libraries and system-specific commands. Here’s a detailed guide on how to achieve this:

1. Introduction

Monitoring disk space is crucial for system administrators and users to avoid running out of storage, which can lead to various issues. This article will guide you through creating a Python script that works across Windows, Linux, and macOS.

2. Prerequisites

• Python installed on your system (Python 3.x is recommended).
• Basic knowledge of Python programming.
• Familiarity with the command line on your operating system.

3. Cross-Platform Compatibility

The psutil library in Python provides an easy way to retrieve information about system utilization (such as CPU, memory, disks, network, sensors) in a cross-platform way. We will use this library to monitor disk space.

Sample code

import psutil
import sys

def check_disk_space():
    partitions = psutil.disk_partitions()
    for p in partitions:
        print(f"Checking partition: {p.device}")
        try:
            usage = psutil.disk_usage(p.mountpoint)
        except PermissionError:
            # This can happen on some systems
            continue

        print(f"  Total Size: {usage.total / (1024 * 1024 * 1024)} GB")
        print(f"  Used: {usage.used / (1024 * 1024 * 1024)} GB")
        print(f"  Free: {usage.free / (1024 * 1024 * 1024)} GB")
        print(f"  Percentage: {usage.percent}%\n")

def main():
    print("Disk Space Monitor\n")
    check_disk_space()

if __name__ == "__main__":
    main()

The script will display information about each partition, including its total size, used space, free space, and the percentage of space used.
