Monitor unique VPN connections

Hello, i’m using CCR1072 as an VPN server and considering the situation that’s goind on in the world everyone need its now.
So, my problem is - i need to monitor every unique vpn connection and make a graph, how many people connect to it every day.
I’m monitoring all my active connections, but can’t realy figure out, how to monitor every unique connection.
Maybe someone has somthing usefull for me?
Thanks.

I use this in the PPP profile for monitoring via a telegram bot

:local ips [/ppp active get [find name=$user] address];
:local up [/ppp active get [find name=$user] uptime];
:local caller [/ppp active get [find name=$user] caller-id];
:local service [/ppp active get [find name=$user] service];
:local active [/ppp active print count];
/tool fetch url="https://api.telegram.org/botXXXXXXXX/sendMessage?chat_id=XXXXX&text=LOGIN%0AUser: $user%0AIP Client: $ips%0ACaller ID: $caller%0AUptime: $up%0ATotal Active: $active%0AService: $service" mode=http keep-result=no;
