Hello. Now my broker gives some new JMX statistics, but I've doubts about the computed values of "DequeueMessageTimestamp" :I supposed it was always the timestamp of the last message consumption, but it seems it's not...
If I create a new queue, send one or more messages into it, and browse and delete immediately at least one message, the value is set with the last consumption (dequeue) time. The same for more messages deletion. On the other hand, we have some queues containing very old messages; when I browse and delete a message from one of them, I expected to have the same last dequeue time, but instead of that, it seems that the dequeue timestamp is set with a rather old timestamp (september 2025), that is probably some attribute of an existing messages. Is it a special behavior because I've added the statistics option later, or will timestamps be computed this way when messages stay a long time in a queue ? This would mean that checking the DequeueMessageTimestamp to verify the actual activity of some slow consumers will not give the expected result ? Thanks for your help. Regards.
