iperf3-python: Python wrapper around iperf3

|PyPi Status| |Build Status| |Coverage Status| |Documentation Status|

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 These might be out of date so installation from the official iperf3 website 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
