Description

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

Parameters

-ClientConfig <AmazonCloudTrailConfig>
Amazon.PowerShell.Cmdlets.CT.AmazonCloudTrailClientCmdlet.ClientConfig
Required?False
Position?Named
Accept pipeline input?True (ByPropertyName)
-CloudWatchLogsLogGroupArn <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. You must use a log group that exists in your account.Not required unless you specify CloudWatchLogsRoleArn.
Required?False
Position?Named
Accept pipeline input?True (ByPropertyName)
-CloudWatchLogsRoleArn <String>
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.

Position?Named
Accept pipeline input?True (ByPropertyName)
-EnableLogFileValidation <Boolean>
Specifies whether log file integrity 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.

For more information about multi-Region keys, see Using multi-Region keys in the Key Management Service Developer Guide.Examples:

Outputs

Amazon.CloudTrail.Model.CreateTrailResponse
This cmdlet returns an Amazon.CloudTrail.Model.CreateTrailResponse object containing multiple properties. The object can also be referenced from properties attached to the cmdlet entry in the $AWSHistory stack.

Examples

Example 1

New-CTTrail -Name="awscloudtrail-example" -S3BucketName="mycloudtrailbucket"
Creates a trail that will use the bucket 'mycloudtrailbucket' for log file storage.

Example 2

$params = @{
    Name="awscloudtrail-example"
    S3BucketName="mycloudtrailbucket"
    S3KeyPrefix="mylogs"
    SnsTopicName="mlog-deliverytopic"
}      
New-CTTrail @params
    
Creates a trail that will use the bucket 'mycloudtrailbucket' for log file storage. The S3 objects representing the logs will have a common key prefix of 'mylogs'. When new logs are delivered to the bucket a notification will be sent to the SNS topic 'mlog-deliverytopic'. This example using splatting to supply the parameter values to the cmdlet.
