Amazon Simple Notification Service (Amazon SNS) has introduced additional usage metrics in Amazon CloudWatch for the following service quotas: ‘Topics per Account’, ‘Filter Policies per Account’, and ‘Pending Subscriptions per Account’. Under the ‘AWS/Usage’ namespace, you can now view the ‘ApproximateNumberOfTopics’, ‘ApproximateNumberOfFilterPolicies’, and ‘ApproximateNumberOfPendingSubscriptions’ metrics to monitor your usage of these Amazon SNS resources.
