Python - get process names,CPU,Mem Usage and Peak Mem Usage in windows

I like using wmic on Windows. You can run it from the command-line, so you can run it from Python.

from subprocess import Popen,PIPE
proc = Popen('wmic cpu',stdout=PIPE, stderr=PIPE)
print str(proc.communicate())

With wmic you can get processes, cpu, and memory info easily. Just use wmic cpu, wmic process, and wmic memphysical. You can also filter out certain attributes by using wmic <alias> get <attribute>. And you can get a list of all commands with wmic /?. Hope that helps!

You can check out the official documentation for WMIC here: http://technet.microsoft.com/en-us/library/bb742610.aspx

You can use psutil.

For example, to obtain the list of process names:

process_names = [proc.name() for proc in psutil.process_iter()]

For info about the CPU use psutil.cpu_percent or psutil.cpu_times. For info about memory usage use psutil.virtual_memory.

Note that psutil works with Linux, OS X, Windows, Solaris and FreeBSD and with python 2.4 through 3.3.
