10User can enable network core stack and socket API calls tracing.
11
12The :kconfig:option:`CONFIG_TRACING_NET_CORE` option controls the core network
13stack tracing. This option is enabled by default if tracing and networking
14are enabled. The system will start to collect the receiving and sending call
15verdicts i.e., whether the network packet was successfully sent or received.
16It will also collect packet sending or receiving timings i.e., how long
17it took to deliver the network packet, and the network interface, priority
18and traffic class used.
19
20The :kconfig:option:`CONFIG_TRACING_NET_SOCKETS` option can be used to track
21BSD socket call usage in the system. It is enabled if tracing and BSD socket
22API support are enabled. The system will start to collect what BSD socket
23API calls are made and what parameters the API calls are using and returning.

25See the :ref:`tracing documentation <tracing>` for how to use the tracing
