===========================================

Detailed documentation at
`iperf3-python.readthedocs.org <https://iperf3-python.readthedocs.org/>`__

iperf3 for python provides a wrapper around the excellent iperf3
utility. iperf3 is a complete rewrite of the original iperf
implementation. more information on the `official iperf3
site <http://software.es.net/iperf/>`__

iperf3 introduced an API called libiperf that allows you to easily
interact with iperf3 from other languages. This library provides a
python wrapper around libiperf for easy integration into your own python
scripts in a pythonic way

Installation
------------

First you have to make sure the iperf3 utility is present on your system as the
python module wraps around the libiperf API provided by it.

The common linux distributions offer installations from their own repositories. These
might be out of date so installation from the official `iperf3 website <http://software.es.net/iperf/>`__
is preferred.

**note** The libiperf API was only introduced in 3.0.6 so make sure you have an updated version
of iperf3 installation.

**note** The libiperf API added a feature to programmatically retrieve the json output from the library. This
enables us to retrieve the results without having to scrape the output from stdout. Effectively this means
that if you want to redirect your script's stdout/stderr to something else you need at least iperf3 version 3.1

- Install from source (preferred)

.. code:: bash

wget http://downloads.es.net/pub/iperf/iperf-3-current.tar.gz
tar xvf iperf-3-current.tar.gz
cd iperf-3.3/ # Or whatever the latest version is
./configure && make && sudo make install

- Ubuntu:

.. code:: bash

sudo apt-get install iperf3

- CenOS/RedHat

.. code:: bash

sudo yum install iperf3

Once the iperf3 utility is installed the simplest way to install the python wrapper is through
`PyPi <https://pypi.python.org/pypi/iperf3>`__

.. code:: bash

pip install iperf3

You can also install directly from the github repository:

.. code:: bash

git clone https://github.com/thiezn/iperf3-python.git
cd iperf3-python
python3 setup.py install

Quickstart
----------

For detailed examples check out the `examples page <http://iperf3-python.readthedocs.io/en/latest/examples.html>`__ or
the detailed documentation at `iperf3-python.readthedocs.org <https://iperf3-python.readthedocs.org/>`__


**Server**

.. code:: python

>>> import iperf3

>>> server = iperf3.Server()
>>> result = server.run()
>>> result.remote_host
"10.10.10.10"

**Client**

.. code:: python

>>> import iperf3

>>> client = iperf3.Client()
>>> client.duration = 1
>>> client.server_hostname = '127.0.0.1'
>>> client.port = 5201
>>> result = client.run()
>>> result.sent_Mbps
32583.293914794922
