From TF

resource "aws_cloudtrail" "test" {
	name                          = "example"
	s3_bucket_name                = "BUCKET_NAME"
	+ is_multi_region_trail         = true
}

From Command Line
To create a trail that applies to all Regions, use the --is-multi-region-trail option. By default, the create-trail command creates a trail that logs events only in the AWS Region where the trail was created.

aws cloudtrail create-trail --name TRAIL_NAME --s3-bucket-name S3_BUCKET_NAME --is-multi-region-trail

CloudTrail

AWS CloudTrail is a service that enables governance, compliance, operational auditing, and risk auditing of your AWS account. With CloudTrail, you can log, continuously monitor, and retain account activity related to actions across your AWS infrastructure. CloudTrail provides event history of your AWS account activity, including actions taken through the AWS Management Console, AWS SDKs, command line tools, and other AWS services. This event history simplifies security analysis, resource change tracking, and troubleshooting.
