AWS::CloudTrail::Trail DataResource
You can configure the DataResource
in an EventSelector
to log data events for the following three resource types:
-
AWS::DynamoDB::Table
-
AWS::Lambda::Function
-
AWS::S3::Object
To log data events for all other resource types including objects stored in
directory buckets, you must use AdvancedEventSelectors. You must also
use AdvancedEventSelectors
if you want to filter on the eventName
field.
Configure the DataResource
to specify the resource type and resource ARNs for which you want to log data events.
Note
The total number of allowed data resources is 250. This number can be distributed between 1 and 5 event selectors, but the total cannot exceed 250 across all selectors for the trail.
The following example demonstrates how logging works when you configure logging of all
data events for a general purpose bucket named amzn-s3-demo-bucket1
. In this example, the CloudTrail user specified an empty prefix, and the option to log both Read
and Write
data events.
-
A user uploads an image file to
amzn-s3-demo-bucket1
. -
The
PutObject
API operation is an Amazon S3 object-level API. It is recorded as a data event in CloudTrail. Because the CloudTrail user specified an S3 bucket with an empty prefix, events that occur on any object in that bucket are logged. The trail processes and logs the event. -
A user uploads an object to an Amazon S3 bucket named
arn:aws:s3:::amzn-s3-demo-bucket1
. -
The
PutObject
API operation occurred for an object in an S3 bucket that the CloudTrail user didn't specify for the trail. The trail doesn’t log the event.
The following example demonstrates how logging works when you configure logging of AWS Lambda data events for a Lambda function named MyLambdaFunction, but not for all Lambda functions.
-
A user runs a script that includes a call to the MyLambdaFunction function and the MyOtherLambdaFunction function.
-
The
Invoke
API operation on MyLambdaFunction is an Lambda API. It is recorded as a data event in CloudTrail. Because the CloudTrail user specified logging data events for MyLambdaFunction, any invocations of that function are logged. The trail processes and logs the event. -
The
Invoke
API operation on MyOtherLambdaFunction is an Lambda API. Because the CloudTrail user did not specify logging data events for all Lambda functions, theInvoke
operation for MyOtherLambdaFunction does not match the function specified for the trail. The trail doesn’t log the event.
Syntax
To declare this entity in your AWS CloudFormation template, use the following syntax:
Properties
Type
-
The resource type in which you want to log data events. You can specify the following basic event selector resource types:
-
AWS::DynamoDB::Table
-
AWS::Lambda::Function
-
AWS::S3::Object
Additional resource types are available through advanced event selectors. For more information about these additional resource types, see AdvancedFieldSelector.
Required: Yes

Values
-
An array of Amazon Resource Name (ARN) strings or partial ARN strings for the specified resource type.
-
To log data events for all objects in all S3 buckets in your AWS account, specify the prefix as
arn:aws:s3
.Note
This also enables logging of data event activity performed by any user or role in your AWS account, even if that activity is performed on a bucket that belongs to another AWS account.
-
To log data events for all objects in an S3 bucket, specify the bucket and an empty object prefix such as
arn:aws:s3:::amzn-s3-demo-bucket1/
. The trail logs data events for all objects in this S3 bucket. -
To log data events for specific objects, specify the S3 bucket and object prefix such as
arn:aws:s3:::amzn-s3-demo-bucket1/example-images
. The trail logs data events for objects in this S3 bucket that match the prefix. -
To log data events for all Lambda functions in your AWS account, specify the prefix as
arn:aws:lambda
.Note
This also enables logging of
Invoke
activity performed by any user or role in your AWS account, even if that activity is performed on a function that belongs to another AWS account. -
To log data events for a specific Lambda function, specify the function ARN.
Note
Lambda function ARNs are exact. For example, if you specify a function ARN arn:aws:lambda:us-west-2:111111111111:function:helloworld, data events will only be logged for arn:aws:lambda:us-west-2:111111111111:function:helloworld. They will not be logged for arn:aws:lambda:us-west-2:111111111111:function:helloworld2.
-
To log data events for all DynamoDB tables in your AWS account, specify the prefix as
arn:aws:dynamodb
.
