Monitor Microsoft RRAS

We have about 10 Microsoft Terminal servers running RRAS (Routing and Remote Access Server) for VPN users.
1 server is for microsoft vpn and the others are for terminal servers.
Is there a way to monitor how many users are logged in using microsoft vpn. And how many users are logged into the terminal servers with AD creds?
I enabled snmp service via the services manager.

Under the graphs tab there is a section for Users Logged In. Logged in users show 165 users. The server shows 75.
I cant figure a way to see the amount of vpn connections.
