How to Monitor Amazon SQS with CloudWatch
Amazon SQS is a message queuing service that allows you to send and receive huge numbers of messages from a queue using a simple API. Using Amazon SQS, without setting up any infrastructure, you can have a distributed and fault tolerant queuing system. Since SQS is a managed service, you have less visibility with traditional monitoring tools. As such, it becomes even more important to take advantage of the available monitoring tools in AWS.
