## Properties
`AdvancedEventSelectors`
Specifies the settings for advanced event selectors. You can use advanced event selectors to log management events, data events for all resource types, and network activity events.
You can add advanced event selectors, and conditions for your advanced event selectors, up to a maximum of 500 values for all conditions and selectors on a trail. You can use either `AdvancedEventSelectors` or `EventSelectors`, but not both. If you apply `AdvancedEventSelectors` to a trail, any existing `EventSelectors` are overwritten. For more information about advanced event selectors, see [Logging data events](https://docs.aws.amazon.com/awscloudtrail/latest/userguide/logging-data-events-with-cloudtrail.html) and [Logging network activity events](https://docs.aws.amazon.com/awscloudtrail/latest/userguide/logging-network-events-with-cloudtrail.html) in the *AWS CloudTrail User Guide*.
*Required*: No
*Type*: Array of [AdvancedEventSelector](aws-properties-cloudtrail-trail-advancedeventselector.md)
*Update requires*: [No interruption](https://docs.aws.amazon.com/AWSCloudFormation/latest/UserGuide/using-cfn-updating-stacks-update-behaviors.html#update-no-interrupt)
`AggregationConfigurations`
Property description not available.
*Required*: No
*Type*: Array of [AggregationConfiguration](aws-properties-cloudtrail-trail-aggregationconfiguration.md)
*Maximum*: `1`
*Update requires*: [No interruption](https://docs.aws.amazon.com/AWSCloudFormation/latest/UserGuide/using-cfn-updating-stacks-update-behaviors.html#update-no-interrupt)
`CloudWatchLogsLogGroupArn`
Specifies a log group name using an Amazon Resource Name (ARN), a unique identifier that represents the log group to which CloudTrail logs are delivered. You must use a log group that exists in your account.
To enable CloudWatch Logs delivery, you must provide values for `CloudWatchLogsLogGroupArn` and `CloudWatchLogsRoleArn`.
If you previously enabled CloudWatch Logs delivery and want to disable CloudWatch Logs delivery, you must set the values of the `CloudWatchLogsRoleArn` and `CloudWatchLogsLogGroupArn` fields to `""`.
*Required*: No
*Type*: String
*Update requires*: [No interruption](https://docs.aws.amazon.com/AWSCloudFormation/latest/UserGuide/using-cfn-updating-stacks-update-behaviors.html#update-no-interrupt)
`CloudWatchLogsRoleArn`
Specifies the role for the CloudWatch Logs endpoint to assume to write to a user's log group. You must use a role that exists in your account.
To enable CloudWatch Logs delivery, you must provide values for `CloudWatchLogsLogGroupArn` and `CloudWatchLogsRoleArn`.
If you previously enabled CloudWatch Logs delivery and want to disable CloudWatch Logs delivery, you must set the values of the `CloudWatchLogsRoleArn` and `CloudWatchLogsLogGroupArn` fields to `""`.
*Required*: No
*Type*: String
*Update requires*: [No interruption](https://docs.aws.amazon.com/AWSCloudFormation/latest/UserGuide/using-cfn-updating-stacks-update-behaviors.html#update-no-interrupt)
`EnableLogFileValidation`
Specifies whether log file validation is enabled. The default is false.
When you disable log file integrity validation, the chain of digest files is broken after one hour. CloudTrail does not create digest files for log files that were delivered during a period in which log file integrity validation was disabled. For example, if you enable log file integrity validation at noon on January 1, disable it at noon on January 2, and re-enable it at noon on January 10, digest files will not be created for the log files delivered from noon on January 2 to noon on January 10. The same applies whenever you stop CloudTrail logging or delete a trail.
*Required*: No
*Type*: Boolean
*Update requires*: [No interruption](https://docs.aws.amazon.com/AWSCloudFormation/latest/UserGuide/using-cfn-updating-stacks-update-behaviors.html#update-no-interrupt)
`EventSelectors`
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.
*Required*: No
*Type*: Array of [EventSelector](aws-properties-cloudtrail-trail-eventselector.md)
*Maximum*: `5`
*Update requires*: [No interruption](https://docs.aws.amazon.com/AWSCloudFormation/latest/UserGuide/using-cfn-updating-stacks-update-behaviors.html#update-no-interrupt)
`IncludeGlobalServiceEvents`
Specifies whether the trail is publishing events from global services such as IAM to the log files.
*Required*: No
*Type*: Boolean
*Update requires*: [No interruption](https://docs.aws.amazon.com/AWSCloudFormation/latest/UserGuide/using-cfn-updating-stacks-update-behaviors.html#update-no-interrupt)
`InsightSelectors`
A JSON string that contains the Insights types you want to log on a trail. `ApiCallRateInsight` and `ApiErrorRateInsight` are valid Insight types.
The `ApiCallRateInsight` Insights type analyzes write-only management API calls that are aggregated per minute against a baseline API call volume.
The `ApiErrorRateInsight` Insights type analyzes management API calls that result in error codes. The error is shown if the API call is unsuccessful.
*Required*: No
*Type*: Array of [InsightSelector](aws-properties-cloudtrail-trail-insightselector.md)
*Update requires*: [No interruption](https://docs.aws.amazon.com/AWSCloudFormation/latest/UserGuide/using-cfn-updating-stacks-update-behaviors.html#update-no-interrupt)
`IsLogging`
Whether the CloudTrail trail is currently logging AWS API calls.
*Required*: Yes
*Type*: Boolean
*Update requires*: [No interruption](https://docs.aws.amazon.com/AWSCloudFormation/latest/UserGuide/using-cfn-updating-stacks-update-behaviors.html#update-no-interrupt)
`IsMultiRegionTrail`
Specifies whether the trail applies only to the current Region or to all Regions. The default is false. If the trail exists only in the current Region and this value is set to true, shadow trails (replications of the trail) will be created in the other Regions. If the trail exists in all Regions and this value is set to false, the trail will remain in the Region where it was created, and its shadow trails in other Regions will be deleted. As a best practice, consider using trails that log events in all Regions.
*Required*: No
*Type*: Boolean
*Update requires*: [No interruption](https://docs.aws.amazon.com/AWSCloudFormation/latest/UserGuide/using-cfn-updating-stacks-update-behaviors.html#update-no-interrupt)
`IsOrganizationTrail`
Specifies whether the trail is applied to all accounts in an organization in AWS Organizations, or only for the current AWS account. The default is false, and cannot be true unless the call is made on behalf of an AWS account that is the management account for an organization in AWS Organizations. If the trail is not an organization trail and this is set to `true`, the trail will be created in all AWS accounts that belong to the organization. If the trail is an organization trail and this is set to `false`, the trail will remain in the current AWS account but be deleted from all member accounts in the organization.
Only the management account for the organization can convert an organization trail to a non-organization trail, or convert a non-organization trail to an organization trail.
*Required*: No
*Type*: Boolean
*Update requires*: [No interruption](https://docs.aws.amazon.com/AWSCloudFormation/latest/UserGuide/using-cfn-updating-stacks-update-behaviors.html#update-no-interrupt)
`KMSKeyId`
Specifies the AWS KMS key ID to use to encrypt the logs and digest files delivered by CloudTrail. The value can be an alias name prefixed by "alias/", a fully specified ARN to an alias, a fully specified ARN to a key, or a globally unique identifier.
CloudTrail also supports AWS KMS multi-Region keys. For more information about multi-Region keys, see [Using multi-Region keys](https://docs.aws.amazon.com/kms/latest/developerguide/multi-region-keys-overview.html) in the *AWS Key Management Service Developer Guide*.

## Return values
### Ref
When the logical ID of this resource is provided to the Ref intrinsic function, `Ref` returns the resource name.
For more information about using the `Ref` function, see [https://docs.aws.amazon.com/AWSCloudFormation/latest/TemplateReference/intrinsic-function-reference-ref.html](https://docs.aws.amazon.com/AWSCloudFormation/latest/TemplateReference/intrinsic-function-reference-ref.html).
### Fn::GetAtt
The `Fn::GetAtt` intrinsic function returns a value for a specified attribute of this type. The following are the available attributes and sample return values.
For more information about using the `Fn::GetAtt` intrinsic function, see [https://docs.aws.amazon.com/AWSCloudFormation/latest/TemplateReference/intrinsic-function-reference-getatt.html](https://docs.aws.amazon.com/AWSCloudFormation/latest/TemplateReference/intrinsic-function-reference-getatt.html).
####
`Arn`
When you pass the logical ID of this resource to the intrinsic `Ref` function, `Ref` returns the ARN of the CloudTrail trail, such as `arn:aws:cloudtrail:us-east-2:123456789012:trail/myCloudTrail`.
`SnsTopicArn`
When you pass the logical ID of this resource to the intrinsic `Ref` function, `Ref` returns the ARN of the Amazon SNS topic that's associated with the CloudTrail trail, such as `arn:aws:sns:us-east-2:123456789012:mySNSTopic`.
## Examples
You can configure a trail using either `AdvancedEventSelectors` or `EventSelectors`. `EventSelectors` are limited to management events and data events for the following resource types: `AWS::DynamoDB::Table`, `AWS::Lambda::Function`, and `AWS::S3::Object`. In contrast, you can use `AdvancedEventSelectors` to configure data events for all available resource types as well as management events.

### Example: Create a trail by using advanced event selectors
The following example creates a trail that logs events in all regions, an Amazon S3 bucket where logs are published, and an Amazon SNS topic where notifications are sent. This example uses `AdvancedEventSelectors` to log all read-only and write-only management events, and data events for all Amazon S3 buckets except the S3 bucket for the trail logs. The bucket and topic policies allow CloudTrail (from the specified regions) to publish logs to the S3 bucket and to send notifications to an email that you specify. For information about CloudTrail bucket policies, see [Amazon S3 Bucket Policy](https://docs.aws.amazon.com/awscloudtrail/latest/userguide/create_trail_bucket_policy.html) in the *AWS CloudTrail User Guide*.
