Hi, I was struggling with the same issue.
The following lines in the default standalone.conf have given me a hint: # Uncomment to add a Java agent. If an agent is added to the module options, then jboss-modules.jar is added as an agent # on the JVM. This allows things like the log manager or security manager to be configured before the agent is invoked. # MODULE_OPTS="-javaagent:agent.jar" I solved it by configuring the javaagent using the MODULE_OPTS env variable. E.g.: MODULE_OPTS="-javaagent:$JBOSS_HOME/prometheus/jmx-prometheus.jar=$PROMETHEUS_PORT:$JBOSS_HOME/prometheus/config.yaml" Kind regards [email protected] schrieb am Donnerstag, 30.
