Thanks, I'll update that.

Use tags from the current context (they include tags emitted by the oc-library-agent-exporter)?

Great reminder, that'd entail changing that to tes.Context(), thanks.

Thank you for the review @bogdandrutu! |
Instrument interceptor/opencensus with stats to record the number of received spans. This is accomplished by a helper to process spans that sends over spans even if the number of spans is 0. Also record with tag_key "opencensus_interceptor" whose value is the name of the respective interceptor. The test to ensure that 0 length spans are also added is currently disabled because: * Issue census-instrumentation/opencensus-go#862 is not yet implemented which requests that the OpenCensus-Go stats worker provide a method Flush to flush all data. Without it, metrics will contain stale data from previous tests. Add tests to lock-in this behavior. Also replace grpc.NewServer with a stats enabled server helper call. This enables tracing and metrics for each gRPC server by replacing naked usages of grpc.NewServer with the new helper function: internal.GRPCServerWithObservabilityEnabled Updates #63
