Capture Requests and Responses From AWS Services

Overview

AWS Payload Extraction captures request and response data exchanged between your application and AWS services. This feature attaches the extracted information as tags to your traces, enabling you to view the data in dashboards and use it for alerting.

Requirements

The following AWS services are supported:

  • Amazon Simple Notification Service (SNS)
  • Amazon Simple Queue Service (SQS)
  • Amazon Kinesis
  • Amazon S3
  • Amazon EventBridge

The following tracer versions and AWS SDK packages are supported:

LanguageVersionInstrumented AWS SDK Packages
Node.js5.25.0+ or 4.49.0+@aws-sdk/* (AWS SDK v3)
Java1.42.1+aws-sdk-v2
Python2.17.0+botocore (including boto3)

How it works

AWS Payload Extraction extracts key-value pairs from hierarchical request and response bodies, converting them into dot-separated tags. For example:

Input JSON:

{  
  "Message": {  
    "foo.bar": "baz",  
    "Arr": ["a", "b"]  
  }  
}

Generated tags:

aws.request.body.Message.foo\.bar: baz  
aws.request.body.Message.Arr.0: a  
aws.request.body.Message.Arr.1: b

The tracers are configured to match JSON data nested inside JSON documents, which is a common pattern with SQS payloads.

General configuration

Enable AWS Payload Extraction

To enable AWS Payload Extraction, set these environment variables:

# Parse requests
DD_TRACE_CLOUD_REQUEST_PAYLOAD_TAGGING=all

# Parse responses  
DD_TRACE_CLOUD_RESPONSE_PAYLOAD_TAGGING=all

You can choose to parse:

  • Only request bodies
  • Only response bodies
  • Both request and response bodies

The value all indicates that the entire body is used to generate tags. See Protect sensitive information for more configuration options.

Protect sensitive information

It’s expected that many of these payloads contain personally identifiable information (PII).

To protect sensitive information, the tracers replace common PII fields with 'redacted' (such as phone numbers in SNS). Note: You can’t disable the default redactions.

You can specify additional fields to redact using JSONPath syntax in the environment variables. For example:

DD_TRACE_CLOUD_REQUEST_PAYLOAD_TAGGING=$.Metadata.UserId,$.Attributes.0.Pass

This example:

  • Redacts the UserId field within the Metadata object
  • Redacts the Pass field in the first element of the Attributes array
  • Applies default redactions
  • Processes request bodies only
Redaction rules apply across all services and cannot be configured per service.

Control payload extraction depth

Control the maximum depth of payload extraction with:

DD_TRACE_CLOUD_PAYLOAD_TAGGING_MAX_DEPTH=10

The default value is 10. Nodes beyond this depth are ignored during tag generation. The main reason to modify this value is to adjust performance.

Disable AWS Payload Extraction

Setting these variables to an empty string or omitting them disables the feature:

DD_TRACE_CLOUD_REQUEST_PAYLOAD_TAGGING=""
DD_TRACE_CLOUD_RESPONSE_PAYLOAD_TAGGING=""

Language-specific configuration

Each tracer implementation provides additional configuration options specific to that language.

Supported services

The following services are supported:

  • SNS
  • SQS
  • Kinesis
  • S3
  • EventBridge
To request support for additional services, open a feature request with the Datadog Support team.

Default redaction rules

The Node.js tracer applies redaction rules on a per-service basis. For example:

  • The $.Endpoint field is redacted only for SNS service requests.
  • Other tracers redact this field across all services.

Supported services

The following services are supported:

  • SNS
  • SQS
  • Kinesis
  • S3
  • EventBridge

Configure services

To enable tag extraction for additional services, use this environment variable:

# Default values
DD_TRACE_CLOUD_PAYLOAD_TAGGING_SERVICES=s3,sns,sqs,kinesis,eventbridge

Add services by appending to the comma-separated list. For example, to add support for AWS Amplify:

DD_TRACE_CLOUD_PAYLOAD_TAGGING_SERVICES=s3,sns,sqs,kinesis,eventbridge,amplify
Added services do not include default redactions. Test your application in staging to identify and configure necessary redactions.

Service naming

Service names are case-sensitive and use lowercase. To find valid service names:

  1. Visit the Boto3 Available Services page.
  2. Click the service name you want to use.
  3. Use the service name from the boto3.client() call.

Configure the number of extracted tags

Control the maximum number of extracted tags with:

# Default value
DD_TRACE_CLOUD_PAYLOAD_TAGGING_MAX_TAGS=758
The default value (758) is the maximum the Datadog Agent can accept. Increasing this value is not recommended.

Supported services

The following services are supported:

  • SNS
  • SQS
  • Kinesis
  • S3
  • EventBridge
  • API Gateway

Configure services

To enable tag extraction for additional services, use this environment variable:

# Default values
DD_TRACE_CLOUD_PAYLOAD_TAGGING_SERVICES=ApiGateway,ApiGatewayV2,EventBridge,Sqs,Sns,S3,Kinesis
Added services do not include default redactions. Test your application in staging to identify and configure necessary redactions.

Service naming

Service names are case-sensitive and use PascalCase. To find a service name:

  1. Generate a trace that includes the AWS service.
  2. Find the service span.
  3. Look for the aws_service field.

For example:

  • For AWS SSO, the resource name is Sso.GetRoleCredentials.
  • The aws_service field shows Sso.
  • Use Sso in your configuration.

Configure the number of extracted tags

Control the maximum number of extracted tags with:

DD_TRACE_CLOUD_PAYLOAD_TAGGING_MAX_TAGS=758
The default value (758) is the maximum the Datadog Agent can accept. Increasing this value is not recommended.

Best practices

  • Different tracers use different JSONPath implementations, so test your queries with each tracer individually.
  • Always verify redaction behavior in a Staging environment before enabling in Production.
