rpc.response.metadata
Developmenttemplate[string[]]as of v1.44.0
RPC response metadata, <key> being the normalized RPC metadata key (lowercase), the value being the metadata values.
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.response.metadata.my-custom-key attribute with value ["attribute_value"]
Examples
- ["attribute_value"]
