Options

--name (string)

Specifies the name of the trail. The name must meet the following requirements:

  • Contain only ASCII letters (a-z, A-Z), numbers (0-9), periods (.), underscores (_), or dashes (-)
  • Start with a letter or number, and end with a letter or number
  • Be between 3 and 128 characters
  • Have no adjacent periods, underscores or dashes. Names like my-_namespace and my--namespace are invalid.
  • Not be in IP address format (for example, 192.168.5.4)

--s3-bucket-name (string)

Specifies the name of the Amazon S3 bucket designated for publishing log files. See Amazon S3 Bucket Naming Requirements .

--s3-key-prefix (string)

Specifies the Amazon S3 key prefix that comes after the name of the bucket you have designated for log file delivery. For more information, see Finding Your CloudTrail Log Files . The maximum length is 200 characters.

--sns-topic-name (string)

Specifies the name of the Amazon SNS topic defined for notification of log file delivery. The maximum length is 256 characters.

--include-global-service-events | --no-include-global-service-events (boolean)

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

--is-multi-region-trail | --no-is-multi-region-trail (boolean)

Specifies whether the trail is created in the current region or in all regions. The default is false.

--enable-log-file-validation | --no-enable-log-file-validation (boolean)

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 will 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.

--cloud-watch-logs-log-group-arn (string)

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. Not required unless you specify CloudWatchLogsRoleArn.

--cloud-watch-logs-role-arn (string)

Specifies the role for the CloudWatch Logs endpoint to assume to write to a user's log group.

--kms-key-id (string)

Specifies the 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.

Examples:

  • alias/MyAliasName
  • arn:aws:kms:us-east-1:123456789012:alias/MyAliasName
  • arn:aws:kms:us-east-1:123456789012:key/12345678-1234-1234-1234-123456789012
  • 12345678-1234-1234-1234-123456789012

--cli-input-json (string) Performs service operation based on the JSON string provided. The JSON string follows the format provided by --generate-cli-skeleton. If other arguments are provided on the command line, the CLI values will override the JSON-provided values.

--generate-cli-skeleton (string) Prints a JSON skeleton to standard output without sending an API request. If provided with no value or the value input, prints a sample input JSON that can be used as an argument for --cli-input-json. If provided with the value output, it validates the command inputs and returns a sample output JSON for that command.

Examples

To create a trail

The following create-trail command creates a multi-region trail named Trail1 and specifies an S3 bucket:

aws cloudtrail create-trail --name Trail1 --s3-bucket-name my-bucket --is-multi-region-trail

Output:

{
  "IncludeGlobalServiceEvents": true,
  "Name": "Trail1",
  "TrailARN": "arn:aws:cloudtrail:us-west-2:123456789012:trail/Trail1",
  "LogFileValidationEnabled": false,
  "IsMultiRegionTrail": true,
  "S3BucketName": "my-bucket"
}

Output

Name -> (string)

Specifies the name of the trail.

S3BucketName -> (string)

Specifies the name of the Amazon S3 bucket designated for publishing log files.

S3KeyPrefix -> (string)

Specifies the Amazon S3 key prefix that comes after the name of the bucket you have designated for log file delivery. For more information, see Finding Your CloudTrail Log Files .

SnsTopicName -> (string)

This field is deprecated. Use SnsTopicARN.

SnsTopicARN -> (string)

Specifies the ARN of the Amazon SNS topic that CloudTrail uses to send notifications when log files are delivered. The format of a topic ARN is:

arn:aws:sns:us-east-1:123456789012:MyTopic

IncludeGlobalServiceEvents -> (boolean)

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

IsMultiRegionTrail -> (boolean)

Specifies whether the trail exists in one region or in all regions.

TrailARN -> (string)

Specifies the ARN of the trail that was created. The format of a trail ARN is:

arn:aws:cloudtrail:us-east-1:123456789012:trail/MyTrail

LogFileValidationEnabled -> (boolean)

Specifies whether log file integrity validation is enabled.

CloudWatchLogsLogGroupArn -> (string)

Specifies the Amazon Resource Name (ARN) of the log group to which CloudTrail logs will be delivered.

CloudWatchLogsRoleArn -> (string)

Specifies the role for the CloudWatch Logs endpoint to assume to write to a user's log group.

KmsKeyId -> (string)

Specifies the KMS key ID that encrypts the logs delivered by CloudTrail. The value is a fully specified ARN to a KMS key in the format:

arn:aws:kms:us-east-1:123456789012:key/12345678-1234-1234-1234-123456789012
