3 Essential Alarms for your AWS SQS Queue

AWS SQS queues require proper monitoring to ensure event-driven architectures function correctly. Three essential CloudWatch alarms should be configured: message production monitoring using NumberOfMessagesSent metric, consumer activity detection combining ApproximateNumberOfMessagesVisible and NumberOfMessagesReceived metrics, and dead letter queue monitoring using ApproximateNumberOfMessagesVisible. These alarms can be implemented using the Serverless Framework with specific YAML configurations that trigger SNS notifications when thresholds are breached.
