Cellular Monitor with the following procedure.

Enable the RTT trace backend in your device's application using the Kconfig
option CONFIG_NRF_MODEM_LIB_TRACE_BACKEND_RTT in the prj.conf file.
-
Ensure your device is running supported modem firmware, see Minimum requirements and limitations and note the version for playback.
-
Use the J-link RTT logger to collect the trace or traces and save in binary
(.bin) format.
-
Load and playback the trace in Cellular Monitor.
