psutil (process and system utilities) is a cross-platform library for
retrieving information on running processes and system utilization (CPU,
memory, disks, network) 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 command
line tools such as: ps, top, lsof, netstat, ifconfig, who, df, kill, free,
nice, ionice, iostat, iotop, uptime, pidof, tty, taskset, pmap. It
currently supports Linux, Windows, OSX, Sun Solaris, FreeBSD, OpenBSD and
NetBSD, both 32-bit and 64-bit architectures, with Python versions from 2.6
to 3.5 (users of Python 2.4 and 2.5 may use 2.1.3 version). PyPy is also
known to work.
