[Openvpn-users] Bandwidth monitoring based on IP address

[Peter D. <pet...@pr...>]

Hello,
I want to know how much bandwidth each client is using. What tool would be useful for this? For example, the following users are connected to my OpenVPN server:

Virtual Address,Common Name,Real Address,Last Ref
10.10.0.12,USER1,X.X.X.X:11975,2025-11-28 21:28:41
10.10.0.2,USER2,X.X.X.X:55645,2025-11-28 21:28:41
10.10.0.7,USER3,X.X.X.X:12564,2025-11-28 21:28:41
10.10.0.11,USER4,X.X.X.X:22152,2025-11-28 21:28:34
10.10.0.3,USER5,X.X.X.X:58136,2025-11-28 21:28:39
10.10.0.8,USER6,X.X.X.X:26612,2025-11-28 21:28:41

I need a program that tells me how much bandwidth the IP address 10.10.0.12 is using, for example.

Thank you.
