Paul Sokolovsky 028aae1ec9 net: config: Rename Kconfig options to correspond to library name This finishes refactor of splitting off net_config library name from net_app library, started in `c60df1311`, `c89a06dbc`. This commit makes sure that Kconfig options are prefixed with CONFIG_NET_CONFIG_ instead of CONFIG_NET_APP_, and propagates these changes thru the app configs in the tree. Also, minor dependency, etc. tweaks are made. Signed-off-by: Paul Sokolovsky <paul.sokolovsky@linaro.org>		2018-08-13 18:42:31 -07:00

Network Statistics Sample Application
#####################################

Overview
********

This sample shows how to query (and display) network statistics from a user
application.

The source code for this sample application can be found at:
:file:`samples/net/stats`.

Requirements
************

- :ref:`networking_with_qemu`

Building and Running
********************

A good way to run this sample application is with QEMU as described in
:ref:`networking_with_qemu`.

Follow these steps to build the network statistics sample application:

.. zephyr-app-commands::
   :zephyr-app: samples/net/stats
   :board: <board to use>
   :conf: prj.conf
   :goals: build
   :compact:

If everything is configured correctly, the application will periodically print
current network statistics to the console.

.. code-block:: console
