Summary

psutil (process and system utilities) is a cross-platform library for
retrieving information on running processes and system utilization
(CPU, memory, disks, network, sensors) in Python.
It is useful mainly for system monitoring, profiling and limiting process
resources and management of running processes.
It implements many functionalities offered by classic UNIX command line tools
such as ps, top, iotop, lsof, netstat, ifconfig, free and others.
psutil currently supports the following platforms:

  • Linux
  • Windows
  • macOS
  • FreeBSD, OpenBSD, NetBSD
  • Sun Solaris
  • AIX

...both 32-bit and 64-bit architectures. Supported Python versions are 2.6, 2.7 and 3.4+. PyPy3 <http://pypy.org/>__ is also known to work.

:alt: Downloads

There are over
10.000 open source projects <https://libraries.io/pypi/psutil/dependent_repositories?page=1>__
on github which depend from psutil.
Here's some I find particularly interesting:
