Message queues
Message queues provide lightweight storage for messages. They take the form of either a queue (where a single message is retrieved by exactly one consumer application) or a topic (in which case a single message is published to all subscribers of the topic). Message queues offer endpoints that allow producer applications to send messages to them. Message queues also offer endpoints that allow consumer applications to retrieve messages from them asynchronously or to subscribe to topics. Decoupled services are common in applications built with microservices, and events are used to communicate between services, making it important to have full observability into the performance of message queues.

Queues and topics in Dynatrace
Dynatrace OneAgent automatically detects queues and topics as part of distributed traces when they’re used in service-to-service communications, resulting in queue entities in Dynatrace.
In the Dynatrace menu, go to Queues to list all detected queues and topics.
- For all queues and topics, Dynatrace OneAgent measures the number of Incoming messages and Outgoing messages. By monitoring these metrics, you can catch unbalanced message processing that could result in severe problems, such as queue overflows, and prevent them by scaling queues quickly or maintaining failover processes.
- Select the Name of a specific queue or topic to display the analytics view of the selected queue or topic, with enhanced troubleshooting capabilities to gain additional insight into related anomalies.
