I’m currently instrumenting a .NET application to send telemetry to Splunk Observability Cloud using the Splunk Distribution of OpenTelemetry. I can successfully see traces, spans, and infrastructure metrics in the dashboard, but runtime metrics (GC, memory, thread pool, exceptions, etc.) are not appearing for my service. I have followed the official Splunk documentation for .NET instrumentation, yet I do not see any configuration block related to runtime metrics in the docs. My current setup is deployed via Helm and Kubernetes manifests, and I want everything to be fully declarative. Traces and spans are flowing fine, and infrastructure metrics (CPU, memory at the host level) are visible.
Do .NET applications instrumented with Splunk OTel automatically produce runtime metrics, or is there a separate step to enable them?
If runtime metrics need to be explicitly enabled, what is the official, supported way to do this for .NET apps?
Is there any documented reference from Splunk that explains enabling runtime metrics for .NET applications? I want to avoid relying on unofficial or community-inferred environment variables and stick to officially supported methods.
Any guidance, examples, or references would be highly appreciated! Thank you in advance.
