Recording total bandwidth used during a period

[battle]

I may have to go to a new ISP.  The one I have now is unlimited bandwidth.  If I move to another location, I may be limited to a certain amount of BW and need to chose the best ISP per price and bandwidth allowed.  I therefore need to see how much bandwidth I am using a month.  Is there any way I can monitor or log how much BW I am using daily/ weekly/monthly in OPNsense or Zenarmor?  Is there a plugin that might be used for that?

You could setup Observium and monitor OPNsense via SNMP. That's what I do.

I am using the VnStat plugin

That looks good, but I am running Windows 7.

I am not finding that in System:Firmware/Plugins.  Can it be loaded from somewhere else?

Look for os-vnstat after adding the gmumail repository https://www.routerperformance.net/opnsense-repo/
