Memory Usage

I have uploaded a python script here that can be added to a server and run by the root user. This script is useful when looking into what services are using what amount of memory.

The script can just be run with python ~/ps_mem.py (if it's uploaded in the user's home directory). It is usually more helpful to pipe the output to a grep command to look for a certain service e.g. python ~/ps_mem.py | grep php-fpm

The output for the unfiltered command will look like the below:
