Proxmox Backup Server network traffic (programming.dev)

Hey all! I'm running Proxmox VE with the tteck PBS LXC and I can't figure out why there is this constant network traffic on PBS. I have backups set to run in the early morning and the screenshot is from when it should be idle. Any ideas? I know I'm not providing much info here so any clarifying questions are welcome since I don't know what would be important for troubleshooting. Thanks!

Hmmm - interesting. I hadn't bothered to check before now, but I'm seeing something similar on one of the two PBS CTs I run.

Comparing the output of netstat -lantop on both CTs, I can see that the one with more outbound traffic has more waiting connections from localhost on port 82, the port Proxmox Backup Servers provides its API over:

I'm wondering if the graph is pulling aggregated network data, including the loopback interface. If so, and it's all just port 82 stuff on 127.0.0.1, then it's probably nothing to worry about.

Edit: found this forum post that seems to indicate it's aggregating all the byte values from /proc/dev/net, so this is probably nothing to worry about if your netstat output, like mine, only shows API conections to/from 127.0.0.1 on port 82.

Yep, I think you're spot on! Glad I asked, I don't think I would've ever thought of that. Thanks!
