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 from **2.6 to 3.6**. `PyPy <http://pypy.org/>`__ is also known to work. ==================== Example applications ==================== +------------------------------------------------------------------------------------------------+--------------------------------------------------------------------------------------------+ | .. image:: https://github.com/giampaolo/psutil/blob/master/docs/_static/procinfo-small.png | .. image:: https://github.com/giampaolo/psutil/blob/master/docs/_static/top-small.png | | :target: https://github.com/giampaolo/psutil/blob/master/docs/_static/procinfo.png | :target: https://github.com/giampaolo/psutil/blob/master/docs/_static/top.png | +------------------------------------------------------------------------------------------------+--------------------------------------------------------------------------------------------+ | .. image:: https://github.com/giampaolo/psutil/blob/master/docs/_static/procsmem-small.png | .. image:: https://github.com/giampaolo/psutil/blob/master/docs/_static/pmap-small.png | | :target: https://github.com/giampaolo/psutil/blob/master/docs/_static/procsmem.png | :target: https://github.com/giampaolo/psutil/blob/master/docs/_static/pmap.png | +------------------------------------------------------------------------------------------------+--------------------------------------------------------------------------------------------+ Also see `scripts directory <https://github.com/giampaolo/psutil/tree/master/scripts>`__ and `doc recipes <http://psutil.readthedocs.io/#recipes/>`__. ===================== Projects using psutil ===================== At the time of writing psutil has roughly `2.9 milion downloads <https://github.com/giampaolo/psutil/issues/1053#issuecomment-340166262>`__ per month and there are over `6000 open source projects <https://libraries.io/pypi/psutil/dependent_repositories?page=1>`__ on github which depend from psutil.
