Export Counter Values for a specific date

Hi,
I am currently looking for a way to bulk display/export a lot of counter values for a specific date.

The idea behind this would be to obtain the energy values for the monthly or annual bill. The values are all available in Observium and I would like to avoid using other software for this.

I imagine this as in the view: /health/metric=counter/
Except that I can still select the time period for the value displayed in the list.

Is this possible?

Thanks!
