:name: Network statistics
:relevant-api: net_stats
Query and display network statistics from a user application.

********
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:
:zephyr_file:`samples/net/stats`.
Requirements
************
- :ref:`networking_with_host`
Building and Running
********************
A good way to run this sample application is with QEMU or native_sim board
as described in :ref:`networking_with_host`.
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.
