pip install psutil

1. Getting CPU Information:

import psutil

# Get CPU information

cpu_count = psutil.cpu_count()

cpu_percent = psutil.cpu_percent(interval=1)

print("CPU Count:", cpu_count)

print("CPU Percent:", cpu_percent)

#clcoding.com 

CPU Count: 8

CPU Percent: 6.9

2. Getting Memory Information:

import psutil

​

# Get memory information

memory = psutil.virtual_memory()

​

total_memory = memory.total

available_memory = memory.available

used_memory = memory.used

percent_memory = memory.percent

​

print("Total Memory:", total_memory)

print("Available Memory:", available_memory)

print("Used Memory:", used_memory)

print("Memory Percent:", percent_memory)

​

#clcoding.com

Total Memory: 8446738432

Available Memory: 721600512

Used Memory: 7725137920

Memory Percent: 91.5

4. Getting Process Information:

252

import psutil

​

# Get information for a specific process

pid = 252  # Replace with the process ID of interest

process = psutil.Process(pid)

​

print("Process Name:", process.name())

print("Process Status:", process.status())

print("Process CPU Percent:", process.cpu_percent(interval=1))

print("Process Memory Info:", process.memory_info())

​

#clcoding.com

Process Name: chrome.exe

Process Status: running

Process CPU Percent: 0.0

Process Memory Info: pmem(rss=29597696, vms=24637440, num_page_faults=14245, peak_wset=37335040, wset=29597696, peak_paged_pool=635560, paged_pool=635560, peak_nonpaged_pool=21344, nonpaged_pool=17536, pagefile=24637440, peak_pagefile=33103872, private=24637440)

5. Killing a Process:

import psutil

# Kill a process

pid_to_kill = 10088  

# Replace with the process ID to kill

process_to_kill = psutil.Process(pid_to_kill)

process_to_kill.terminate()

6. Getting Disk Usage:

import psutil

​

# Get disk usage information

disk_usage = psutil.disk_usage('/')

​

total_disk_space = disk_usage.total

used_disk_space = disk_usage.used

free_disk_space = disk_usage.free

disk_usage_percent = disk_usage.percent

​

print("Total Disk Space:", total_disk_space)

print("Used Disk Space:", used_disk_space)

print("Free Disk Space:", free_disk_space)

print("Disk Usage Percent:", disk_usage_percent)

​

#clcoding.com
