How to Get System Information Using Python

Introduction

In this tutorial, we will be looking at how to get system information such as CPU percentage, disk usage, memory usage, CPU count, and many more using python. To begin will need to install a module psutil which is a cross-platform library for system and process monitoring in python.

Install module

To install our psutil module run the command below.

pip3 install psutil

Create app

Now let’s create a file called app.py and import the library below.

import psutil

CPU percentage

cpu_usage = psutil.cpu_percent()
print(f"CPU usage: {cpu_usage}%")

Output

CPU usage: 0.0%

CPU count

cpu_count = psutil.cpu_count(logical=False)
print(f"CPU count: {cpu_count}")

Output

CPU count: 2

Logged in users

try:
    for user in psutil.users():
        print("Username:", user.name)
except psutil.NotImplementedError:
    print("Unable to retrieve user information on this platform.")

Output

Username: kali

Memory statistics

memory_stats = psutil.virtual_memory()
print(f"Total memory: {memory_stats.total / 1024 / 1024} MB")
print(f"Available memory: {memory_stats.available / 1024 / 1024} MB")
print(f"Memory usage: {memory_stats.percent}%")

Output

Total memory: 3504.26953125 MB
Available memory: 628.75 MB
Memory usage: 82.1%

Disk usage

disk_stats = psutil.disk_usage('/')
print(f"Total disk space: {disk_stats.total / 1024 / 1024 / 1024} GB")
print(f"Used disk space: {disk_stats.used / 1024 / 1024 / 1024} GB")
print(f"Free disk space: {disk_stats.free / 1024 / 1024 / 1024} GB")
print(f"Disk usage: {disk_stats.percent}%")

Output

Total disk space: 456.4401626586914 GB
Used disk space: 284.88196182250977 GB
Free disk space: 148.30224609375 GB
Disk usage: 65.8%

There you have it, Thanks for reading. Happy Coding
