問題文
A service emits traces and metrics but the team cannot tell which Kubernetes pod produced a slow span. Which concept is intended to carry that kind of information?
選択肢
- The instrumentation scope, which is intended to describe the infrastructure the process happens to be running on at the time of the export.
- Baggage, which is the only mechanism that survives the export to a backend and can carry the pod name with it.
- The span name, by embedding the pod name into it.
- The Resource, which represents the entity producing the telemetry as a set of resource attributes.
