I use Debian 12.8 with Mate 1.26.0 as desktop.
My primary browser is SeaMonkey 2.53.21 .
My internet connection was sold by T-Mobile as a "WiFi Hotspot".
[I have the WiFi disabled thus essentially using it as a high speed modem]
My service has a LOW data cap which I occasionally exceed.
I wish to log essentially daily cumulative totals for my usage.
Mate's System Monitor will give me _current_ usage but I'm looking for a
scriptable tool to essentially log daily usage for a month at a time.
[ T-Mobile software reports cumulative usage for *ONLY* current month. ]
What should I search for?
I was pointed to vnstat.
If I only knew how to set things up so *NO MANY* times I did power
on/off cycles of the T-Mobile device the data would still be gathered.
All the instructions I've seen depend on device naming conventions that
Debian has not used since Stretch.
