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: samples/net/stats.
Requirements¶
Building and Running¶
A good way to run this sample application is with QEMU or native_posix board as described in Networking with the host system.
Follow these steps to build the network statistics sample application:
west build -b <board to use> samples/net/stats -- -DCONF_FILE=prj.conf
If everything is configured correctly, the application will periodically print current network statistics to the console.
