Unrouted Message Count and Address Size Metrics
Hi. Can someone please tell me what “unrouted.message.count” is? I am seeing several topics with the number of unrouted messages over 100k, and I am not sure if this is a concern or not.
I am also interested in what “Address size” is.
There is not much in the documentation on these metrics unless I missed something: https://activemq.apache.org/components/artemis/documentation/2.13.0/metrics.html
Regards,
William Crowell

I'm not sure but I think the descriptions are written somewhere in the
properties of corresponding object class in the Artemis source code and
used by the metrics plugin.
For example, I have found the descriptions here:
https://github.com/apache/activemq-artemis/blob/23522fd83d3c16ca637223fa336103a73bd86905/artemis-core-client/src/main/java/org/apache/activemq/artemis/api/core/management/AddressControl.java#L28
Unrouted messages are just dropped because they should not be sent to any
queue on the address.
Messages with incorrect routing type also can not be routed (for example,
multicast messages which are sent to the address with anycast queue).

Another question I would have is: Are unrouted messages kept in memory or just dropped?

Hi William,
I have configured metrics plugin which works as a Prometheus exporter.
Usually every exporter has a small description for each metric, which is
available on the /metrics endpoint as # HELP text.
Unrouted messages count is the number of messages which were sent to the
address and have not been routed to any queue bound to this address (for
example - message was filtered out or queue was disabled).
Address size is "the number of estimated bytes being used by all the

Re: Unrouted Message Count and Address Size Metrics
Posted by Justin Bertram <jb...@apache.org>.
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.
