When I query my server's network interface stats using either ifconfig or ip -s they're limited to 999GB and then roll over to 0GB, starting again. Is it possible to change the configuration somehow to allow stats logging in the terabyte range? Or use a different logging tool? I'm using Ubuntu 20.04.

$ uname -p

$ lsb_release -a

Many thanks.

Edit to add requested information. enp4s0 is the LAN side of my firewall and the total has only recently just reset back to 0GB. I'll provide updates in due course.

ifconfig output:

Both ifconfig and ip show stats in appropriate unit depending on the amount of data to be displayed. Can you provide outputs showing before and after unit rollover?

Here's output from Ubuntu 16.04.4 x86_64 server:
