I'm testing this JMX Exporter <https://github.com/prometheus/jmx_exporter>
with ActiveMQ to get metrics. Per instructions in this post, I setup the
jar as a Java agent.
<https://www.openlogic.com/blog/prometheus-java-monitoring-and-gathering-data>
Here are the changes in the activemq/bin/env file:
if [ -z "$ACTIVEMQ_OPTS" ] ; then
ACTIVEMQ_OPTS="$ACTIVEMQ_OPTS_MEMORY
-Djava.util.logging.config.file=logging.properties
-Djava.security.auth.login.config=$ACTIVEMQ_CONF/login.config"
fi
ACTIVEMQ_OPTS="$ACTIVEMQ_OPTS
-javaagent:/apps/jmx_exporter/jmx_prometheus_javaagent-0.13.0.jar=localhost:8042:/apps/jmx_exporter/config.yml"
It starts correctly, and the metrics are accessible over the configured
port, but when I stop ActiveMQ, I get the following exception below. Does
anyone know why this is occurring ?
