CreateSink - Amazon CloudWatch Observability Access Manager


Use this to create a sink in the current account, so that it can be used as a monitoring account in CloudWatch cross-account observability. A sink is a resource that represents an attachment point in a monitoring account. Source accounts can link to the sink to send observability data.

After you create a sink, you must create a sink policy that allows source accounts to attach to it. For more information, see PutSinkPolicy.

Each account can contain one sink per Region. If you delete a sink, you can then create a new one in that Region.
