Azure Service Bus Dead-Letter Queue Monitoring
Azure Service Bus, a cloud-based messaging service, facilitates communication between applications and services. Within Azure Service Bus queues and topic subscriptions, there exists an additional sub-queue known as a Azure Service Bus dead-letter queue (DLQ). The Dead-Letter Queue (DLQ) serves as a storage area for messages that the receiving application from the main queue cannot deliver or process successfully. These messages are referred to as “dead-lettered” messages.
