Implement Serverless Service Representation (SSR) in AWS Lambda #7850

rithikanarayan · 2025-11-20T21:05:28Z

Summary of changes

Fixes the Serverless Service Representation (SSR) for Dotnet.
In serverless environments, sets peer.service tag for outbound AWS managed service spans to {service type}.{region}.amazonaws.com:

SQS: sqs.us-east-1.amazonaws.com
SNS: sns.us-east-1.amazonaws.com
Kinesis: kinesis.us-east-1.amazonaws.com
Eventbridge: events.us-east-1.amazonaws.com
s3: bucket-name.s3.us-east-1.amazonaws.com
Dynamodb: dynamodb.us-east-1.amazonaws.com

Sets peer.service.source to peer.service for these serverless cases.

In non-serverless cases we assign the peer.service tag to the values of the following tags:

SQS: AwsSqsTags.QueueName
SNS: AwsSnsTags.TopicName
Kinesis: AwsKinesisTags.StreamName
Eventbridge: AwsEventBridgeTags.RuleName
S3: AwsS3Tags.BucketName
Dynamodb: AwsDynamoDbTags.TableName
StepFunctions: AwsStepFunctionsTags.StateMachineName

Sets peer.service source to the respective tag itself. (Ex. for an SQS queue with the name "MyQueue", peer.service = "MyQueue" and peer.service.source = "queuename").

Adds DerivePeerService function in Util/PeerServiceHelpers to do the above assignments.

Implementation details

See summary of changes.

Test coverage

Covered by AWS integration tests in non-serverless case. Tested functionality in AWS Lambda by using custom dd-trace-dotnet layer with arn:arn:aws:lambda:us-east-1:425362996713:layer:ssr-dotnet-rithika:14 on a sample app that had an API Gateway trigger a producer lambda, which sent data through Kinesis, SQS, SNS, and EventBridge to consumer lambdas, which wrote to S3 and DynamoDB. Visually inspected the service map (see images in Reason for change section) to check for correct labelling of the inferred spans for these services. Also checked tags in the trace overview to confirm the correct values of the peer.service and peer.service.source tags.

Comparison explanation

Execution-time benchmarks measure the whole time it takes to execute a program, and are intended to measure the one-off costs. Cases where the execution time results for the PR are worse than latest master results are highlighted in **red**. The following thresholds were used for comparing the execution times:

Welch test with statistical test for significance of 5%
Only results indicating a difference greater than 5% and 5 ms are considered.

Note that these results are based on a single point-in-time result for each branch. For full results, see the dashboard.

Graphs show the p99 interval based on the mean and StdDev of the test run, as well as the mean value of the run (shown as a diamond below the graph).

tracer/src/Datadog.Trace/Util/PeerServiceHelpers.cs

+            var service = tags.AwsService;
+            var region = tags.Region;
+            var isAwsLambda = EnvironmentHelpers.IsAwsLambda();
+            if (isAwsLambda && tags.Region != null)


going to replace tags.Region with region (variable declared two lines above)

tracer/src/Datadog.Trace/Util/PeerServiceHelpers.cs

+                switch (service)
+                {
+                    case "DynamoDB":
+                        if (tags is AwsDynamoDbTags)


will replace this pattern with if (tags is AwsDynamoDbTags dbTags) to avoid the declaration of var dbTags in the next line

Add DerivePeerService and call it in RuntimePipeline integrations
