I’m working on a system that uses AWS SNS/SQS as its messaging platform, which has around 100 queues, each of them having its own DLQ.

e.g.:

• queue-001 / queue-001_dlq.
• queue-002 / queue-002_dlq.
• […]
• queue-100 / queue-100_dlq.

I would like to receive a notification when any of the DLQs receives a message (ApproximateNumberOfMessagesVisible >= 1).

What is the recommended approach to monitor all these queues?

• Is there a way of configuring a single alarm for all these queues?
• Should I just create an alarm per queue?
