Amazon Simple Notification Service message filtering now adds support for Amazon CloudWatch Metrics

Amazon CloudWatch can be used to monitor the performance of the Amazon SNS service when utilizing the subscription filter policies. Simple Notification Service is a managed subscribe/publish messaging service for highly reliable and high throughput message delivery. The message filtering capability of Amazon SNS offloads message filtering logic from the publishers. This will simplify the subscribe/publish architectures. When you deploy the SNS solution the Amazon Cloud Watch metrics will monitor as to how many messages are filtered which is based on the filter policy and also how many are filtered due to invalid or missing message attributes.
