Hi,
I apologize for the inconvenience this might cause you, there may not be something implemented that could meet your requirements, but you should be able to develop your own implementation at the application level having a record of the required (and available) network/stack events and generate some logs using DBG_vPrintf() (for ZGWUI log).
Some of the available events can be found in app_zcl_event_handler.c and app_general_events_handler.c
Regards,
Eduardo.
