[Observium] LXC monitoring via SNMP

I'm monitoring 3 LXC containers of my new installed homelab server but somehow the CPU values polled via SNMP are completely messy while checking inside the container with TOP they are correct there. Attached is a screenshot of one of three fresh installed LXC containers where they are doing nothing yet showing the CPU utilization via SNMP and TOP. Also the physical server does nothing and is showing the correct values via SNMP and TOP. Anyone know how to fix that?

thx, cody
