The addition of WireGuard is AWESOME! Thank you! If there was one other want it would be for a service to monitor WAN IP and e-mail any changes. Trying a ZABBIX solution now, but not so intuitive…
WireGuard is a very lightweight protocol and has a very small handshake. It does not have the same state of a connection being established or notified to be closed like IPsec or OpenVPN have. Therefore there is no logging information available.
so without any logging information then I would not expect a graph to be able to be created as there would be no data.
