Constant RPC_GRPC_RESPONSE_METADATA
pub const RPC_GRPC_RESPONSE_METADATA: &'static str;
Expand description
gRPC response metadata, key
being the normalized gRPC Metadata key (lowercase), the value being the metadata values.
§Notes
Instrumentations SHOULD require an explicit configuration of which metadata values are to be captured. Including all response metadata values can be a security risk - explicit configuration helps avoid leaking sensitive information.
For example, a property my-custom-key
with value ["attribute_value"]
SHOULD be recorded as
the rpc.grpc.response.metadata.my-custom-key
attribute with value ["attribute_value"]
§Examples
"[\"attribute_value\"]"
