Introducing a new console experience for AWS WAF
You can now use the updated experience to access AWS WAF functionality anywhere in the console. For more details, see Working with the updated console experience.
AWS Firewall Manager notifications
AWS Firewall Manager doesn't record metrics, so you can't create Amazon CloudWatch alarms specifically for Firewall Manager. However, you can configure Amazon SNS notifications to alert you to potential attacks. To create Amazon SNS notifications in Firewall Manager, see Step 4: Configuring Amazon SNS notifications and Amazon CloudWatch alarms.
