Answer 1

The broker doesn't hold on to historical data about which message was acknowledged by which consumer. However, you can enable logging which will give you these details in real time.

First, configure the LoggingActiveMQServerPlugin in broker.xml as follow:

      <broker-plugins>
         <broker-plugin class-name="org.apache.activemq.artemis.core.server.plugin.impl.LoggingActiveMQServerPlugin">
            <property key="LOG_DELIVERING_EVENTS" value="true"/>
         </broker-plugin>
      </broker-plugins>

Second, enabled DEBUG logging for org.apache.activemq.artemis.core.server.plugin.impl in log4j2.properties, e.g.:

logger.artemis_utils.name=org.apache.activemq.artemis.core.server.plugin.impl
logger.artemis_utils.level=DEBUG
