Collecting Containers metrics and Hostsystem metrics with node-exporter?. How can I do this? - windows

Question

My hostmachine is a windows system and I'm running docker desktop. I've running prometheus / node-exporter / cadvisor and grafana in a container.
Currently I get only the metrics of the containers, not from the windows host system.
How is it possible to collect data from host system?
There is a simular question in Stackoverflow but this not work for me, probably it's for a linux host system.

You'll need to run your exporters directly as Windows processes to get metrics from your host. Otherwise, containers are running in a Linux hypervisor, and that's what you'd be getting metrics from with host.docker.internal references.
