About

Custom Dynatrace JMX plugins for ActiveMQ Artemis broker processes.

Artemis Overview Plugin

This plugin provides general broker statistics such as address memory usage, connection/consumer count, total message count, total messages added/acknowledged rate.

Artemis Queues Plugin

This provides detailed per-queue statistics such as current message count, messages added/acknowledged rate, consumer counts.

IMPORTANT: Activating the Artemis Queues Plugin on brokers with a VERY large number of queues may result in an overload of the broker process (100% CPU usage, denial of service) caused by the thousands of periodic JMX requests made by Dynatrace.
