ActiveMQ is a message broker that facilitates message routing between different services using standard protocols, offering two versions—Classic and Artemis—that will eventually merge into a single version. Both versions support high-throughput, synchronous and asynchronous messaging, enabling connections between loosely coupled services in various programming languages. Datadog has enhanced its integration to monitor both ActiveMQ Classic and Artemis, allowing users to collect and analyze metrics, view logs, and use tags to correlate data, thus gaining comprehensive insight into messaging infrastructure. ActiveMQ supports point-to-point and publish/subscribe messaging, organizing messages in queues or addresses, and runs on the Java Virtual Machine, necessitating monitoring of JVM and host resources to ensure optimal performance. Datadog allows users to monitor memory usage, which is crucial for maintaining application health, and offers tools to collect logs and apply tags for correlating metrics, logs, and traces, enhancing troubleshooting capabilities. The integration simplifies monitoring all ActiveMQ components, providing a holistic view of system performance and contributing to the overall health of applications.
