Filed under: linux — Tags: , , , — admin @ 10:27 pm

Create with following contents :

#! /usr/bin/python3

import json, psutil, datetime, sys, time

f = open('memory_usage_'+sys.argv[1]+'.log', 'a')

while True:

Make it executable :

chmod +x

Usage :

./ PID

By default it logs the memory usage info every 60 seconds in a file named memory_usage_PID.log in the same folder, if you want, you can change time.sleep(60) in the code to suit your needs.
