what is the best way to setup seeing all the traffic going to the emulator? I want to connect an ELM327 to the emulator, send some commands and see how the traffic is being formatted. I also want to do this with my ESP32 connecting to the emulator via a CAN Shield

You can use a CAN bus sniffer or monitoring tool, like Wireshark with a CAN interface, to capture and analyze the traffic between the ELM327 or ESP32 with the emulator.
