[Observium] Traffic Bill

Hi,

thanks for the development of observium!

I want to use Observium to calculate the traffic of my clients.

Now I have the following problem:

Under "used" always "0B" is displayed.

The same goes for "Over Usage" where only "-" is displayed.

In the bar where the traffic usage should be displayed in percent is nothing.

In the observium main directory I have found the file poll- billing.php

I run it, but unfortunately nothing has happened here.

I would be very grateful for a little assistance.

For your information: Observium 0.13.9.4451
