RoS V.4 Total Wireless Hotspot Connections

RouterOS Scripting
1

I have a simple question.I want to get the total number of connections to a wireless or a hotspot interface.I just want to see for ex. in a month how many users connected wirelessly to my hotspots.
I am able to get live how many users are in a hotspot interface (http://forum.mikrotik.com/t/netwatch-on-web-script/24843/1) but not the total since the beginning.

Is there a way to get this value through winbox or using the above script and storing them in a database or in the router?

Feature request for 5.0 final.

at this moment all you can do is to collect that information and store it somewhere else, then make necessary statistical analysis of the collected data.
