Traffic monitoring of ASUS RT-AX86U dual WAN ports in load balancing mode

[Beth]

I am looking for some direction on best and simplest way to monitor traffic from each of the dual WAN ports. Basically, where should I start. Most of the analytics features are disabled in load balancing mode, but I'd like to see traffic volume in and out of those router ports to confirm my load balancing ratio of 1:1 and monitor the internet speeds from both carriers. I read somewhere that the ASUS load balancing mode basically pushes traffic based upon the ratio set.
Merlin firmware version 388.1
TIA!

Using a SNMP monitor will do a great job at this yet it means choosing one and setting it up.
