------------------------------------
Summary: Add a JMX attribute for the number of messages received
by an address
Key: ARTEMIS-1855
URL: https://issues.apache.org/jira/browse/ARTEMIS-1855
Project: ActiveMQ Artemis
Issue Type: New Feature
Reporter: Lionel Cons
On a broker with {{multicastPrefix}} set to emulate the standard STOMP
destinations, I am sending messages (using a STOMP producer) to {{/topic/test}}
when there are no consumers.
The "number of messages" attributes (both {{MessageCount}} and
{{NumberOfMessages}}) stay at 0. FWIW, they get incremented when using a queue
instead of a topic.
This is not really a bug since these attributes are documented as
* {{MessageCount}}: number of messages added to all the queues for this address
* {{NumberOfMessages}}: the sum of messages on queue(s), including messages in
delivery
For monitoring purposes, I want to track the number of messages received by a
topic, even with no consumers (so no queues) attached. The goal is to get the
incoming message rate.
Could one or more JMX attributes be added to keep track of all received
messages?
Note that this is tricky because, with the current implementation, both
{{/topic/test}} and {{/queue/test}} use the same {{test}} address. Since these
two destinations are different (see also ARTEMIS-1794), they should get
different counters for incoming messages.
