Spring / Spring gRPC Interview Questions

How would you monitor gRPC service performance in a Spring Boot application?

A common approach layers a metrics-recording ServerInterceptor (or uses one provided by the starter, where available) that captures per-call latency, status codes, and message counts, and publishes them through Micrometer - the same metrics facade Spring Boot Actuator already uses for REST endpoints, so gRPC metrics can flow into the same dashboards.

For end-to-end visibility, distributed tracing context (trace and span IDs) is propagated through gRPC Metadata the same way it would ride in HTTP headers for REST, so a request that crosses both REST and gRPC hops still shows up as one connected trace rather than disjointed fragments.

What metrics facade do gRPC interceptor-based metrics commonly integrate with in Spring Boot?
How is distributed tracing context typically propagated across a gRPC call?
