Missing network traffic metrics when running Netdata inside a Proxmox VM

Hi everyone

I’m new to Netdata, so sorry in advance if this is not the right place to ask. I have a Proxmox setup and I noticed the following behavior:

If I install Netdata on the Proxmox host using

curl https://get.netdata.cloud/kickstart.sh > /tmp/netdata-kickstart.sh && sh /tmp/netdata-kickstart.sh

I can see all network-related metrics (traffic, interfaces, etc.) without any issues. However, if I run the exact same command inside an Ubuntu VM running on that Proxmox host, Netdata does not show any network traffic data at all. Everything else seems to work fine, just not the network traffic inside the VM.

Is this expected behavior in virtualized environments like Proxmox, or am I missing some configuration on the VM side?

Thanks a lot for any guidance, and please let me know if I should ask this somewhere else


That is a kernel bug. Fixed in https://github.com/netdata/netdata/pull/21507
