Is there an alternative for vnstat network traffic monitor?

Question

After upgrading from Ubuntu 14.04 to 18.04 my USB modem's interface name changed from wwan0 to wwx001e101f0000. I do not mind that and also read this has some good reasons. Unfortunately vnstat stopped working for this interface:

$ vnstat -i wwx001e101f0000
Error: Unable to read database "/var/lib/vnstat/wwx001e101f0000": No such file or directory

It works properly for ethernet interface enp4s0:

$ vnstat

I would need some alternative to measure consumed data as I use this modem with limited amount of data available (LTE modem). Is there any alternative? I found just a lot of tools which offers real time traffic monitoring, but I need the historical data.

I realized vnstat will work properly even for interface wwx001e101f0000 but I had to do this:

sudo vnstat -u -i wwx001e101f0000
Error: Unable to read database "/var/lib/vnstat/wwx001e101f0000": No such file or directory
Info: -> A new database has been created.

And then set this in /etc/vnstat.conf

# default interface
Interface "wwx001e101f0000"

So the problem is solved.

Is there an alternative for vnstat network traffic monitor?
