Solves. #6991
This PR implements the request portion of the new gRPC metadata
instrumentation spec:
https://github.com/open-telemetry/opentelemetry-specification/blob/main/specification/trace/semantic_conventions/rpc.md#grpc-request-and-response-metadata
The changes include:
- new CommonConfig entry for desired gRPC metadata values:
'otel.instrumentation.grpc.capture-metadata.request'
(Similar to http headers)
- setting the desired metadata values in GrpcTelemetry
- new property in GrpcAttributesExtractor that holds a reference to the
GrpcRpcAttributesGetter
- new property in GrpcAttributesExtractor that stores the desired values
so it can iterate them and extract each one from the request
- inject the GrpcRpcAttributesGetter to GrpcAttributesExtractor (in
GrpcTelemetryBuilder)
- logic in GrpcRpcAttributesGetter to safely extract the gRPC metadata
value
- A new test in GrpcTest that makes sure that when a certain metadata
key name is inserted, it also ends up in the span attributes
** Doesn't take care of the response because gRPC response is not
implemented in java-instrumentation yet. (This is absolutely necessary
but out of scope for this PR)
** "metadataValue" is only implemented inside GrpcRpcAttributesGetter
and not in RpcAttributesGetter to avoid providing implementations for
every RpcAttributesGetter in the repo as this PR only focuses on gRPC.
