I imagine there are differences between the protocols which Micrometer supports for metrics plugin integration, but if, for example, you configured the Prometheus metrics plugin and then loaded http://myBroker:8161/metrics/ you would see this (among other things):
... # HELP artemis_routed_message_count number of messages routed to one or more bindings ... # HELP artemis_unrouted_message_count number of messages not routed to any bindings This "help" text is shared by the JMX MBeans and is also found in the JavaDoc for the corresponding management method (e.g. here [1]). Whether a high unrouted.message.count is a concern really depends on your use-case. Unrouted messages are dropped _unless_ you've configured send-to-dla-on-no-route [2] as true and you've got a dead-letter address with a queue to receive those unrouted messages.
