Where is the ASUS RT-AC68U storing all it's logs?

Hello guys,

I have an ASUS RT-AC68U with merlin firmware version 3.0.0.4.374.37_0 and I was wondering if someone knows where is it storing all it's logs?
I am interested in moving them on a mounted HDD.

I was able to move the Traffic Monitoring files to my custom location, but I have no idea on how to move the System Log, Wireless Log, DHCP leases and others (if any).

Cheers,
Josh
