I've tried to enable logging to custom path and have linked to a screenshot showing my settings:
The router is an Asus RT-N66U running the Shibby v100 build of TomatoUSB.
I can still see the web usage site that shows the sites visited and searches made portions.
I can't see any more logs, when I go to view all, the page is blank.
My custom path exists and is writable, but it remains empty with no log files or archives being made.
I think I'm not understanding something about the log location.. does this location need to be a syslog server of some sort? I just don't know how to set that up on my 16GB usb that's mounted at /mnt/Duracell/log/
