inuse_space not working in dotnet?

Hi,

When checking the grafana-agent **_inuse_space_** that's in go_lang, I see a match with the memory usage in my Prometheus metrics:


However when trying to use inuse_space in dotnet, it doesnt seem to be showing us the same results as our metrics, its seems more like a rate


Is this just not possible in dotnet, is it a bug? or am I doing something wrong?

Thanks.
