Hi, will be grateful if anybody can help me out with billing feature of observium.

I used the following guide to set up billing.

http://observium.org/docs/billing/

After which i created bill for our primary internet link, but for some reason bill does not get's generated. All we see on Traffic Accounting panel is zero's.

i ran the cronjob manually.

poll-billing.php

this script run's and details the traffic stats but subsequent script 
which generates the bill

billing-calculate.php

has following output.

#####  Vision Primary [7]  #####

01/01/17 @ 00:00:00 to 01/31/17 @ 23:59:59 Quota    10MB       0B         0% Updated!  Updated history! 

#####  Vision 95thpercentile [14]  #####

#####  Completed billing calculation run at 2017-01-07 19:10:57  #####

Thanks in advance.

Cheers,
