How to measure total memory usage of all processes of a user in Python -

i use these commands see memory usage on servers:

ps -u $username -o pid,rss,command | awk '{print $0}{sum+=$2} end {print "total", sum}' 

what best way collect total sum in python script? had psutil module collects global memory information , there no way filter down user.

it's pretty simple using psutil. can iterate on processes, select ones owned , sum memory returned memory_info().

import psutil import getpass  user = getpass.getuser()  total = sum(p.memory_info()[0] p in psutil.process_iter()                                if p.username == user)  print('total memory usage in bytes: ', total)
