Then the sum of the physical memory occupied by all the httpd processes is counted, and all the memory occupied by the Apache service can be counted.

In [all]: from subprocess import Popen,pipein [+]: P=popen ([' pidof ', ' httpd '],stdout=pipe,stderr=pipe) in [22]: P.stdout.read (). Split () out[22]: [' 13712 ', ' 13711 ', ' 13710 ', ' 13709 ', ' 13708 ', ' 13707 ', ' 13706 ', ' 13705 ', ' 13698 ']
