RUTX10 does not have a mobile modem, so cellular connectivity is unavailable.
On the RMS, it is possible to monitor wireless information about the device. First, you will have to enable wireless monitoring. In the RMS dashboard navigate to Management -> Devices -> Select devices -> Management -> Set monitoring update period -> Move the slider to enable wireless monitoring.
You can then see some of the wireless information in the Management -> Devices -> Device details (action column in the device llist) -> Wi-Fi tab.
Regarding the wired WAN metrics, such information is not available in RMS. Sorry.
In the WebUI of the RUTX10 itself, you can navigate to Status -> Realtime data -> Traffic to see the data traffic in graphs.
You can also navigate to Network -> Interfaces -> General to see the total received (RX) and transmitted (TX) data for each interface.
