Hello,

We are reaching out to notify you that AWS Managed Policy is making a change that will require your action. AWS Managed Policy is deprecating the managed policy "CloudWatchFullAccess" [1] and replacing it with "CloudWatchFullAccessV2" [2]. After December 7, 2023, "CloudWatchFullAccess" will no longer be supported.

We have identified resources in your account with the "CloudWatchFullAccess" managed policy and recommend that you review those resources to replace that managed policy with "CloudWatchFullAccessV2". Please refer to the 'Affected Resources' tab of your AWS Health Dashboard for a list of your resources affected by this change. If you do not take any action, the accounts with the policy attached to a user, group, or role, will continue to see the policy in the account but cannot attach the policy to new users, groups, or roles or view the deprecated policy in the AWS IAM Console.

The new policy includes:

- Autoscaling:Describe permissions so users with this policy can see the Auto Scaling actions that are associated with CloudWatch alarms

- SNS permissions so users with this policy can retrieve or create Amazon SNS topics and associate them with CloudWatch alarms

- IAM permissions so users with this policy can view information about service-linked roles associated with CloudWatch

- The oam:ListSinks and oam:ListAttachedLinks permissions so users with this policy can use the console to view data shared from source accounts in CloudWatch cross-account observability

If you have questions or concerns, please reach out to AWS Support [3].
