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 classic UNIX command line tools
|
||
|
|
such as *ps, top, iotop, lsof, netstat, ifconfig, free* and others.
|
||
|
|
psutil currently supports the following platforms:
|
||
|
|
|
||
|
|
- **Linux**
|
||
|
|
- **Windows**
|
||
|
|
- **macOS**
|
||
|
|
- **FreeBSD, OpenBSD**, **NetBSD**
|
||
|
|
- **Sun Solaris**
|
||
|
|
- **AIX**
|
||
|
|
|
||
|
|
...both **32-bit** and **64-bit** architectures. Supported Python versions are **2.6**, **2.7** and **3.4+**, `PyPy <http://pypy.org/>`__ 2.7 and 3.X.
