Monitoring ActiveMQ Artemis
The ActiveMQ Artemis sensor is automatically installed after you install the Instana agent on the host where the ActiveMQ is running. You can view monitored hosts and metrics that are related to ActiveMQ Artemis in the Instana UI after you configure the sensor. For more information about the configuration of the sensor, see Configuring.
Supported information
Supported versions
Instana ActiveMQ Artemis sensor supports metrics and configuration data for versions: 2.0.0 to 2.6.x. Instana also supports JBoss ActiveMQ 7 and later.
Supported client-side tracing
Instana supports client-side tracing for Java.
Enabling JMX
If JMX is not enabled, the following message is displayed in the Instana UI:
Jmx is not enabled.
You can enable it in activemq config by setting the broker property useJmx to true.
You can enable JMX access by removing <authorisation> element from /apache-artemis/bin/myinstance/etc/management.xml.
Configuring
To enable in-depth metric monitoring, add the queues that you want to monitor to the <agent_install_dir>/etc/instana/configuration.yaml agent configuration file :
com.instana.plugin.activemqartemis:
monitorQueues:
- 'test-queue'
- 'DLQ'
Viewing metrics
To view the metrics, complete the following steps:
- From the navigation menu in the Instana UI, select Infrastructure.
- Click a specific monitored host.
You can see a host dashboard with all the collected metrics and monitored processes.

Health Signatures
Each sensor has a curated knowledgebase of health signatures that are evaluated continuously against the incoming metrics and are used to raise issues or incidents that depend on user impact.
Built-in events trigger issues or incidents based on failing health signatures on entities, and custom events trigger issues or incidents based on the thresholds of an individual metric of any entity.
For information about built-in events for the ActiveMQ Artemis sensor, see Built-in events reference.
