OpenVPN Monitoring

[spacefighter]

Hi, I was looking at d3vih's raspberry-gateway which references a Grafana dashboard to monitor the OpenVPN server. I was wondering how to add this after I installed the openvpn-server and openvpn-ui conatiners. I'm not great with docker, any help would be appreciated. From looking it seems like it needs an Prometheus container, Grafana container, and the openvpn exporter installed in the server container? I want to be able to see current bandwidth usage of each user, i'm assuming this will show that?
