Translate OpenTelemetry system metrics

[axw]

Similar to what we did for JVM metrics (#4919), we should translate OpenTelemetry system metrics to the equivalent metrics produced by Elastic APM agents, if possible, so they appear under the service overview metrics in Kibana.

@axw I love your initiative. Did you evaluate how we should prioritize the "official" system metrics versus the metrics captured by the OpenTelemetry Collector receiver for Host Metrics?

I did some research when filling Map the metrics of the OpenTelemetry Collector Host Metrics Receiver to ECS and store them in the metrics- indices #5310 and it seemed that few of them were slightly different.
I thought of prioritizing the integration of the OpenTelemetry Collector receiver for Host Metrics.

Maybe you have a different perspective .

Related: elastic/kibana#105923. We're not collecting the CPU and thread count metrics for JVM OpenTelemetry.

@cyrille-leclerc no, I did not do any kind of evaluation - I just opened this for tracking.

Is there any development regarding this issue?

Hi, Is there any update on this for dotnet?

Hi, we are trialling the integrations of dotnet apps via k8s auto instrumentation. I am wondering if this change will impact what we see here (currently nothing):

Still nothing with 8.11.3 version. Only traces and logs show up.
