This documentation is a draft for private preview for regions in the AWS European Sovereign Cloud. Documentation content will continue to evolve. Published: December 30, 2025.

Using the update-trail command to update a trail

You can use the update-trail command to change the configuration settings for a trail. You can also use the add-tags and remove-tags commands to add and remove tags for a trail. You can only update trails from the AWS Region where the trail was created (its Home Region). When using the AWS CLI, remember that your commands run in the AWS Region configured for your profile. If you want to run the commands in a different Region, either change the default Region for your profile, or use the --region parameter with the command.

Converting a single-Region trail to a multi-Region trail

To change an existing single-Region trail to a multi-Region trail, use the --is-multi-region-trail option.

aws cloudtrail update-trail --name my-trail --is-multi-region-trail

To confirm that the trail is now a multi-Region trail, verify that the IsMultiRegionTrail element in the output shows true.

{
    "IncludeGlobalServiceEvents": true, 
    "Name": "my-trail", 
    "TrailARN": "arn:aws:cloudtrail:us-east-2:123456789012:trail/my-trail", 
    "LogFileValidationEnabled": false, 
    "IsMultiRegionTrail": true, 
    "IsOrganizationTrail": false,
    "S3BucketName": "amzn-s3-demo-bucket"
}

Converting a multi-Region trail to a single-Region trail

To change an existing multi-Region trail so that it applies only to the Region in which it was created, use the --no-is-multi-region-trail option.

aws cloudtrail update-trail --name my-trail --no-is-multi-region-trail

To confirm that the trail now applies to a single Region, the IsMultiRegionTrail element in the output shows false.

{
    "IncludeGlobalServiceEvents": true, 
    "Name": "my-trail", 
    "TrailARN": "arn:aws:cloudtrail:us-east-2:123456789012:trail/my-trail", 
    "LogFileValidationEnabled": false, 
    "IsMultiRegionTrail": false, 
    "IsOrganizationTrail": false,
    "S3BucketName": "amzn-s3-demo-bucket"
}

Enabling and disabling global service event logging

To change a trail so that it does not log global service events, use the --no-include-global-service-events option.

aws cloudtrail update-trail --name my-trail --no-include-global-service-events

To confirm that the trail no longer logs global service events, the IncludeGlobalServiceEvents element in the output shows false.

{
    "IncludeGlobalServiceEvents": false, 
    "Name": "my-trail", 
    "TrailARN": "arn:aws:cloudtrail:us-east-2:123456789012:trail/my-trail", 
    "LogFileValidationEnabled": false, 
    "IsMultiRegionTrail": false, 
    "IsOrganizationTrail": false,
    "S3BucketName": "amzn-s3-demo-bucket"
}

To change a trail so that it logs global service events, use the --include-global-service-events option.

Enabling log file validation

To enable log file validation for a trail, use the --enable-log-file-validation option. Digest files are delivered to the Amazon S3 bucket for that trail.

aws cloudtrail update-trail --name my-trail --enable-log-file-validation

To confirm that log file validation is enabled, the LogFileValidationEnabled element in the output shows true.

{
    "IncludeGlobalServiceEvents": true, 
    "Name": "my-trail", 
    "TrailARN": "arn:aws:cloudtrail:us-east-2:123456789012:trail/my-trail", 
    "LogFileValidationEnabled": true, 
    "IsMultiRegionTrail": false, 
    "IsOrganizationTrail": false,
    "S3BucketName": "amzn-s3-demo-bucket"
}

Disabling log file validation

To disable log file validation for a trail, use the --no-enable-log-file-validation option.

aws cloudtrail update-trail --name my-trail-name --no-enable-log-file-validation

To confirm that log file validation is disabled, the LogFileValidationEnabled element in the output shows false.

{
    "IncludeGlobalServiceEvents": true, 
    "Name": "my-trail", 
    "TrailARN": "arn:aws:cloudtrail:us-east-2:123456789012:trail/my-trail", 
    "LogFileValidationEnabled": false, 
    "IsMultiRegionTrail": false, 
    "IsOrganizationTrail": false,
    "S3BucketName": "amzn-s3-demo-bucket"
}
