Summary
|
|
=======
|
|
|
|
psutil is a module providing an interface for retrieving information on all
|
|
running processes and system utilization (CPU, memory, disks, network, users) in
|
|
a portable way by using Python, implementing many functionalities offered by
|
|
command line tools such as: **ps, top, df, kill, free, lsof, free, netstat,
|
|
ifconfig, nice, ionice, iostat, iotop, uptime, pidof, tty, who, taskset, pmap**.
|
|
|
|
It currently supports **Linux**, **Windows**, **OSX** and **FreeBSD** both
|
|
**32-bit** and **64-bit** with Python versions from **2.4** to **3.3** by using
|
|
a single code base.
