Monitor bandwidth usage for guest VMs on subnet

[blcksys]

Hello, I haven't found any docs related this (or maybe I'm bad at searching?).
I need to monitor the bandwidth usage of my guest VMs using a subnet.

Is there any days to do that?
Like, have an history of the bandwith usage (in Kbps, Mbps, etc) of the VMs on a specific base/singular?

For example, I have 10.10.10.10 VM1, 10.10.10.11 VM2
For each, have some way to monitor the bandwidth its been used for the VM1 or the VM2 etc

The guest systems are all linux or windows, I can't install anything on them as them are managed by my customers

Proxmox already logs rrd graphs for network traffic per vm.

For wan i would go with a upstream firewall like opnsense.

For lan you can simply install any logging tool that greps your vm network tap adapter stats just like proxmox does.

Combined with Grafana you can get some really nice looking graphs.

Can you give me some more informations on how to achieve that?
I know proxmox does RRD graphs, however doesn't indicate the network speed used (Mbps, etc)

Hello!
I personally use LibreNMS for monitoring and managing network related stuff.
Maybe not directly the thing you are looking for but it does what you want, and you can (if needed) add alerts if a device is using too much data.
