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 UNIX command line tools such as: ps, top, lsof, netstat, ifconfig, who, df, kill, free, nice, ionice, iostat, iotop, uptime, pidof, tty, taskset, pmap. psutil currently supports the following platforms:

  • Linux

  • Windows

  • OSX,

  • FreeBSD, OpenBSD, NetBSD

  • Sun Solaris

  • AIX

…both 32-bit and 64-bit architectures, with Python versions 2.6, 2.7, and 3.4+. PyPy is also known to work.

Projects using psutil

At the time of writing psutil has roughly 2.9 milion downloads per month and there are over 7000 open source projects on github which depend from psutil. Here’s some I find particularly interesting:
