I put artemis-prometheus-metrics-plugin-1.1.0.jar in directory /var/lib/test-broker/lib, then put metrics.war in directory /var/lib/test-broker/web. In /var/lib/test-broker/etc/broker.xml i added to "configuration" scope: <metrics-plugin class-name="org.apache.activemq.artemis.core.server.metrics.plugins.ArtemisPrometheusMetricsPlugin"/> and added: <app url="metrics" war="metrics.war"/> to the WEB element in /var/lib/test-broker/etc/bootstrap.xml.

But still got this error and really don't know what exactly wrong here.

My broker instance example is here: https://github.com/nikzhernovkov357/apache-artemis-broker-example I using this version of ActiveMQ server: 2.8.1

As the error indicates, Artemis 2.8.1 does not contain Micrometer. And since 2.8.1 is very old, I suggest you upgrade to a more recent or the most recent version.
