Summary
=======
2014-12-23 21:45:15 +03:00
psutil (python system and process 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, FreeBSD** and **Sun Solaris**, both **32-bit** and
**64-bit** architectures, with Python versions from **2.4 to 3.4**. PyPy is
also known to work.
