Trying to implement monitoring for ActiveMQ Artemis

Question

After updating the configuration I'm getting this error while running ActiveMQ Artemis

add the jmx in broker.xml:

    <?xml version='1.0'?>


      <configuration xmlns="urn:activemq"
               xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
               xmlns:xi="http://www.w3.org/2001/XInclude"
               xsi:schemaLocation="urn:activemq /schema/artemis-configuration.xsd">

      <core xmlns="urn:activemq:core" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
         xsi:schemaLocation="urn:activemq:core ">

       <name>localhost</name>
      
       <server>

        <jmx-management-enabled>true</jmx-management-enabled>

       </server>     

       <persistence-enabled>true</persistence-enabled>

       <max-redelivery-records>1</max-redelivery-records>
       <journal-type>NIO</journal-type>

Answer 1

The configuration changes you've made are invalid. This is the problem:

<server>
   <jmx-management-enabled>true</jmx-management-enabled>
</server>

You should use this instead:

<jmx-management-enabled>true</jmx-management-enabled>

That said, if you want to use Prometheus with ActiveMQ Artemis I strongly recommend use the metrics subsystem and configure the Prometheus Metrics Plugin. You may run into difficulties with the Prometheus JMX Exporter because ActiveMQ Artemis manages its own embedded MBean server in order to enforce role-based access control.
