Response Structure
The specified trail ARN that has the event selectors.
The event selectors that are configured for the trail.
Use event selectors to further specify the management and data event settings for your trail. By default, trails created without specific event selectors will be configured to log all read and write management events, and no data events. When an event occurs in your account, CloudTrail evaluates the event selector for all trails. For each trail, if the event matches any event selector, the trail processes and logs the event. If the event doesn't match any event selector, the trail doesn't log the event.
You can configure up to five event selectors for a trail.
You cannot apply both event selectors and advanced event selectors to a trail.
Specify if you want your trail to log read-only events, write-only events, or all. For example, the EC2 GetConsoleOutput is a read-only API operation and RunInstances is a write-only API operation.
By default, the value is All .
Specify if you want your event selector to include management events for your trail.
For more information, see Management Events in the CloudTrail User Guide .
By default, the value is true .
The first copy of management events is free. You are charged for additional copies of management events that you are logging on any subsequent trail in the same region. For more information about CloudTrail pricing, see CloudTrail Pricing.
CloudTrail supports data event logging for Amazon S3 objects, Lambda functions, and Amazon DynamoDB tables with basic event selectors. You can specify up to 250 resources for an individual event selector, but the total number of data resources cannot exceed 250 across all event selectors in a trail. This limit does not apply if you configure resource logging for all data events.
For more information, see Data Events and Limits in CloudTrail in the CloudTrail User Guide .
The Amazon S3 buckets, Lambda functions, or Amazon DynamoDB tables that you specify in your event selectors for your trail to log data events. Data events provide information about the resource operations performed on or within a resource itself. These are also known as data plane operations. You can specify up to 250 data resources for a trail.
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.
If you are using advanced event selectors, the maximum total number of values for all conditions, across all advanced event selectors for the trail, is 500.
The following example demonstrates how logging works when you configure logging of all data events for an S3 bucket named bucket-1 . In this example, the CloudTrail user specified an empty prefix, and the option to log both Read and Write data events.
bucket-1 .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.arn:aws:s3:::bucket-2 .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 Lambda data events for a Lambda function named MyLambdaFunction , but not for all Lambda functions.
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.Invoke API operation on MyOtherLambdaFunction is an Lambda API. Because the CloudTrail user did not specify logging data events for all Lambda functions, the Invoke operation for MyOtherLambdaFunction does not match the function specified for the trail. The trail doesn’t log the event.The resource type in which you want to log data events. You can specify the following basic event selector resource types:
AWS::S3::ObjectAWS::Lambda::FunctionAWS::DynamoDB::TableThe following resource types are also available through advanced event selectors. Basic event selector resource types are valid in advanced event selectors, but advanced event selector resource types are not valid in basic event selectors. For more information, see AdvancedFieldSelector$Field.
AWS::CloudTrail::ChannelAWS::S3Outposts::ObjectAWS::ManagedBlockchain::NodeAWS::S3ObjectLambda::AccessPointAWS::EC2::SnapshotAWS::S3::AccessPointAWS::DynamoDB::StreamAWS::Glue::TableAWS::FinSpace::EnvironmentAWS::SageMaker::ExperimentTrialComponentAWS::SageMaker::FeatureGroupAn array of Amazon Resource Name (ARN) strings or partial ARN strings for the specified objects.
arn:aws:s3 .Note
This also enables logging of data event activity performed by any user or role in your Amazon Web Services account, even if that activity is performed on a bucket that belongs to another Amazon Web Services account.
arn:aws:s3:::bucket-1/ . The trail logs data events for all objects in this S3 bucket.arn:aws:s3:::bucket-1/example-images . The trail logs data events for objects in this S3 bucket that match the prefix.arn:aws:lambda .Note
This also enables logging of Invoke activity performed by any user or role in your Amazon Web Services account, even if that activity is performed on a function that belongs to another Amazon Web Services account.
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 .
arn:aws:dynamodb .An optional list of service event sources from which you do not want management events to be logged on your trail. In this release, the list can be empty (disables the filter), or it can filter out Key Management Service or Amazon RDS Data API events by containing kms.amazonaws.com or rdsdata.amazonaws.com . By default, ExcludeManagementEventSources is empty, and KMS and Amazon RDS Data API events are logged to your trail. You can exclude management event sources only in regions that support the event source.
The advanced event selectors that are configured for the trail.
Advanced event selectors let you create fine-grained selectors for the following CloudTrail event record fields. They help you control costs by logging only those events that are important to you. For more information about advanced event selectors, see Logging data events for trails in the CloudTrail User Guide .
readOnlyeventSourceeventNameeventCategoryresources.typeresources.ARNYou cannot apply both event selectors and advanced event selectors to a trail.
An optional, descriptive name for an advanced event selector, such as "Log data events for only two S3 buckets".
Contains all selector statements in an advanced event selector.
A single selector statement in an advanced event selector.
A field in a CloudTrail event record on which to filter events to be logged. For event data stores for Config configuration items, Audit Manager evidence, or non-Amazon Web Services events, the field is used only for selecting events as filtering is not supported.
For CloudTrail event records, supported fields include readOnly , eventCategory , eventSource (for management events), eventName , resources.type , and resources.ARN .
For event data stores for Config configuration items, Audit Manager evidence, or non-Amazon Web Services events, the only supported field is eventCategory .
readOnly - Optional. Can be set to Equals a value of true or false . If you do not add this field, CloudTrail logs both read and write events. A value of true logs only read events. A value of false logs only write events.eventSource - For filtering management events only. This can be set only to NotEquals kms.amazonaws.com .eventName - Can use any operator. You can use it to filter in or filter out any data event logged to CloudTrail, such as PutBucket or GetSnapshotBlock . You can have multiple values for this field, separated by commas.eventCategory - This is required and must be set to Equals .Management or Data .ConfigurationItem .Evidence .ActivityAuditLog .resources.type - This field is required for CloudTrail data events. resources.type can only use the Equals operator, and the value can be one of the following:AWS::CloudTrail::ChannelAWS::S3::ObjectAWS::Lambda::FunctionAWS::DynamoDB::TableAWS::S3Outposts::ObjectAWS::ManagedBlockchain::NodeAWS::S3ObjectLambda::AccessPointAWS::EC2::SnapshotAWS::S3::AccessPointAWS::DynamoDB::StreamAWS::Glue::TableAWS::FinSpace::EnvironmentAWS::SageMaker::ExperimentTrialComponentAWS::SageMaker::FeatureGroupYou can have only one resources.type field per selector. To log data events on more than one resource type, add another selector.
resources.ARN - You can use any operator with resources.ARN , but if you use Equals or NotEquals , the value must exactly match the ARN of a valid resource of the type you've specified in the template as the value of resources.type. For example, if resources.type equals AWS::S3::Object , the ARN must be in one of the following formats. To log all data events for all objects in a specific S3 bucket, use the StartsWith operator, and include only the bucket ARN as the matching value. The trailing slash is intentional; do not exclude it. Replace the text between less than and greater than symbols (<>) with resource-specific information.arn:<partition>:s3:::<bucket_name>/arn:<partition>:s3:::<bucket_name>/<object_path>/When resources.type equals AWS::S3::AccessPoint , and the operator is set to Equals or NotEquals , the ARN must be in one of the following formats. To log events on all objects in an S3 access point, we recommend that you use only the access point ARN, don’t include the object path, and use the StartsWith or NotStartsWith operators.
