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 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**
|
|
- **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/>`__ is also known to work.

|
|
psutil was created and is maintained by
|
|
`Giampaolo Rodola <http://grodola.blogspot.com/p/about.html>`__ and it
|
|
received many useful `contributions <https://github.com/giampaolo/psutil/blob/master/CREDITS>`__
|
|
over the years.
|
|
A lot of time and effort went into making psutil as it is right now.
|

|
|
future development consider making a small donation:
