Ensure multi-regions trail exists for each AWS CloudTrail

AWS CloudTrail is a web service that records AWS API calls for your account and delivers log files to you. The recorded information includes the identity of the API caller, the time of the API call, the source IP address of the API caller, the request parameters, and the response elements returned by the AWS service. CloudTrail provides a history of AWS API calls for an account, including API calls made via the Management Console, SDKs, command line tools, and higher-level AWS services (such as CloudFormation).

From Portal

  3. In the left navigation, click Trails. Select Create trail, enter a Trail name.
  4. In Apply trail to all regions, select Yes.

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
