OpenVPN Statistics for charging

[karanik]

Hello,
Is there any plugin or something else to have billing statistics for OpenVPN connection? For example to charge with hours.

Thank you

I thought charging by time went out with dial up modems.  These days, data connections are either flat rate or by amount of traffic.

I want statistics when someone connect and when disconnect.

For example:
User: karanik
Connected : 14/12/2017, 09:00
Disconnected: 14/12/2017,12:00
Total time of day: 3 hours
Total time of month: 22 hours and 45 minutes

No i have only this status
