Metricbeat CPU percent on Hyper-V Server

hey all,

currently facing a problem with mericbeat on a Windows Server 2019 with Hyper-V role installed. This server is a pure virtualization server, hosting a lot of VMs.

Using metricbeat 7.13.1 and have the following config in my system.yml module:

module: system
period: 10s
cpu.metrics: ["normalized_percentages"]
metricsets:
   - cpu
   - memory

While the memory readings are consistent with what I'm seeing in taskmanager, the cpu metrics are completely off. I figured out, that the performance metrics don't "see" the CPU load created by all the virtual machines running on ther server ... so my CPU load is always around 1%. I tested with some heavy load on the server itself (running prime95) and the load goes up accordingly. Doing the same (running prime95 in a VM) doesn't increase the CPU load seen by metricbeat (but taskmanager shows it).
Is there a way to fix that?

thanks!
