AWS SDK spans

Status:

This span describes an AWS SDK client call.

Span name MUST be of the format Service.Operation as per the AWS HTTP API, e.g., DynamoDB.GetItem, S3.ListBuckets. This is equivalent to concatenating rpc.service and rpc.method with . and consistent with the naming guidelines for RPC client spans.

AWS SDK span attributes are based on the request or response parameters in AWS SDK API calls. The conventions have been collected over time based on feedback from AWS users of tracing and will continue to increase as new interesting conventions are found.

Span kind SHOULD be CLIENT.

Span status SHOULD follow the Recording Errors document.

Attribute	Type	Description	Examples	Requirement Level	Stability
rpc.system	string	The value aws-api.	aws-api	Required
aws.extended_request_id	string	The AWS extended request ID as returned in the response header x-amz-id-2.	wzHcyEWfmOGDIE5QOhTAqFDoDWP3y8IUvpNINCwL9N4TEHbUw0/gZJ+VZTmCNCWR7fezEN3eCiQ=	Conditionally Required If available.
aws.request_id	string	The AWS request ID as returned in the response headers x-amzn-requestid, x-amzn-request-id or x-amz-request-id.	79b9da39-b7ae-508a-a6bc-864b2829c622; C9ER4AJX75574TDJ	Recommended
rpc.method	string	The name of the operation corresponding to the request, as returned by the AWS SDK [1]	GetItem; PutItem	Recommended
rpc.service	string	The name of the service to which a request is made, as returned by the AWS SDK. [2]	DynamoDB; S3	Recommended

[1] rpc.method: This is the logical name of the method from the RPC interface perspective, which can be different from the name of any implementing method/function. The code.function.name attribute may be used to store the latter (e.g., method actually executing the call on the server side, RPC client stub method on the client side).

[2] rpc.service: This is the logical name of the service from the RPC interface perspective, which can be different from the name of any implementing class. The code.namespace attribute may be used to store the latter (despite the attribute name, it may include a class name; e.g., class with method actually executing the call on the server side, RPC client stub class on the client side).

rpc.system has the following list of well-known values. If one of them applies, then the respective value MUST be used; otherwise, a custom value MAY be used.

Value	Description	Stability
apache_dubbo	Apache Dubbo
connect_rpc	Connect RPC
dotnet_wcf	.NET WCF
grpc	gRPC
java_rmi	Java RMI
