使用python在Windows计算机上运行的每个进程的cpu用法，内存，网络详细信息

Question

Hi Sorry I'm new to python. I'm not able to do this, I feel like it's easy but difficult to get the result so pls can anyone help me out this.

Here is my program and output (both actual and expected)

Expected output:

I need to get the details of CPU, Memory and network I/O counter for each process (pid) running on the window machine (local system) but here we are getting overall CPU usage , memory details.

Answer 1

As far as I know, you can monitor cpu and memory usage of individual process using python's psutil library. But for monitoring network i/o of individual process you will need to create a network driver for system which can filter the traffic for particular process. Refer

Here's the solution for memory and cpu usage by process -

import psutil

# For Windows
process_data = {}
for proc in psutil.process_iter():
    print(proc.name())
    process_names[proc.name()] = {'cpu' : proc.cpu_percent(), 'memory': proc.memory_info()}

# For Linux
process_data = {}
for proc in psutil.process_iter():
    print(proc.name())
    process_names[proc.name()] = {'cpu' : proc.cpu_percent(), 'memory': proc.memory_full_info()}

print(process_data)
=> 
{
   'AGSService.exe': 
    {
        'cpu': 0.0,
        'memory': pmem(rss=8949760, vms=3072000, num_page_faults=2589, 
                  peak_wset=8994816, wset=8949760, peak_paged_pool=113696, 
                  paged_pool=111920, peak_nonpaged_pool=17296, 
                  nonpaged_pool=15080, pagefile=3072000,     
                  peak_pagefile=3244032, private=3072000)
     },
 ...}
