CreateTrail - Amazon CloudTrail
Services or capabilities described in Amazon Web Services documentation might vary by Region. To see the differences applicable to the China Regions, see Getting Started with Amazon Web Services in China (PDF).

CreateTrail

Creates a trail that specifies the settings for delivery of log data to an Amazon S3 bucket.

Request Syntax

{ "CloudWatchLogsLogGroupArn": "string", "CloudWatchLogsRoleArn": "string", "EnableLogFileValidation": boolean, "IncludeGlobalServiceEvents": boolean, "IsMultiRegionTrail": boolean, "IsOrganizationTrail": boolean, "KmsKeyId": "string", "Name": "string", "S3BucketName": "string", "S3KeyPrefix": "string", "SnsTopicName": "string", "TagsList": [ { "Key": "string", "Value": "string" } ] }

Request Parameters

For information about the parameters that are common to all actions, see Common Parameters.

The request accepts the following data in JSON format.

CloudWatchLogsLogGroupArn

Specifies a log group name using an Amazon Resource Name (ARN), a unique identifier that represents the log group to which CloudTrail logs will be delivered. You must use a log group that exists in your account.

Not required unless you specify CloudWatchLogsRoleArn.

Type: String

Required: No

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.

Type: String

Required: No

EnableLogFileValidation

Specifies whether log file integrity validation is enabled. The default is false.

Note

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.

Type: Boolean

Required: No

IncludeGlobalServiceEvents

Specifies whether the trail is publishing events from global services such as IAM to the log files.

Type: Boolean

Required: No

IsMultiRegionTrail

Specifies whether the trail is created in the current Region or in all Regions. The default is false, which creates a trail only in the Region where you are signed in. As a best practice, consider creating trails that log events in all Regions.

Type: Boolean

Required: No

IsOrganizationTrail

Specifies whether the trail is created for all accounts in an organization in Amazon Organizations, or only for the current Amazon Web Services account. The default is false, and cannot be true unless the call is made on behalf of an Amazon Web Services account that is the management account or delegated administrator account for an organization in Amazon Organizations.

Type: Boolean

Required: No

KmsKeyId

Specifies the Amazon KMS key ID to use to encrypt the logs 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.
