redis receiver should add hostname to output metrics to filter

What happened?

Description

It seems that when using otelcol-contrib on different redis instances, then as there is no hostname to split views, there is only a global aggregated view when I see data on uptrace side.

Steps to Reproduce

Launch 2 instances of redis with otelcol-contrib defined on it

Expected Result

Being able to filter by hostname

Actual Result

No filter per hostname

Collector version

0.103.0

Environment information

OS: (e.g., "Ubuntu 20.04")

Ok found how to do it, just add the resourcedetection processor and add it in the pipeline configuration

  processors:
    resourcedetection:
      detectors: [env, system]
[...]
  service:
    pipelines:
      traces:
        receivers: [otlp]
        processors: [batch]
        exporters: [otlp/uptrace, debug]
      metrics:
        receivers: [otlp, redis]
        processors: [cumulativetodelta, batch, resourcedetection]
        exporters: [otlp/uptrace, debug]
