> Prometheus and Grafana Monitoring I’m already using this. > “building the project using Maven” Are you trying to rebuild Artemis for this? That should not be needed. I’m using just the regular Artemis distribution. I’m using the following steps after installing the Artemis software and after creating an instance, but before starting the instance: 1. Copy artemis-prometheus-metrics-plugin-*.jar to the “lib” directory of the Artemis instance. 2. Added “<plugin class-name="com.redhat.amq.broker.core.server.metrics.plugins.ArtemisPrometheusMetricsPlugin"/>” to the “<metrics>” section in broker.xml. 3. Copy artemis-prometheus-metrics-plugin-servlet-*.war to the “web” directory of the Artemis instance and renaming it to “metrics.war”. Create the “web” directory when it is not yet there. 4. Added “<app url="metrics" war="metrics.war"/>” to file etc/bootstrap.xml. If you do not rename in the previous step, this war-filename is different. 5. Start the broker and pull the metrics from http://hostname:8161/metrics. 6. The instructions for collecting the metrics and placing them in Prometheus is dependent on your actual environment. 1+2 make sure that Artemis can maintain the needed counters. 3+4 make sure that the counters can be exported in the Prometheus (or metrics) format using http.
