How to distinguish auto exported metrics (e.g. process.runtime.go.mem.heap_alloc) from different hosts?

I use OTLP to export metrics to Grafana.
I uas a "host" attribute to distinguish metrics with the same name on different hosts.
However, I noticed there are a couple of metrics get auto created by the sdk: https://github.com/open-telemetry/opentelemetry-go-contrib/blob/main/instrumentation/runtime/runtime.go#L111-L131
Is it possible to distinguish these metrics from different hosts by adding additional attributes to them?

You can setup a view in your code to change the attributes/names of auto-generated metrics.

Thanks for the response.
I think I am only able to filter attributes, but I don't see how to rename attributes from the API.

Actually, since what you need to do is add attributes and not modify the emitted metrics, what you're looking for is probably resources.
See https://opentelemetry.io/docs/languages/go/resources/

This example is about traces, but setting resources for a meter provider works exactly the same way.
