ARTEMIS-4915 clarify 'total' server metrics' descriptions
> TotalMessagesAdded/Acknowledged metrics are inaccurate if queues deleted
> ------------------------------------------------------------------------
>
> Key: ARTEMIS-4915
> URL: https://issues.apache.org/jira/browse/ARTEMIS-4915
> Project: ActiveMQ Artemis
> Issue Type: Bug
> Components: JMX, management
> Reporter: Josh Byster
> Priority: Minor
> Time Spent: 20m
> Remaining Estimate: 0h
>
> Currently, the total messages added/acknowledged fields are computed by
> summing up the counts on the individual queues, i.e.
> {code:java}
> @Override
> public long getTotalMessagesAdded() {
> long total = 0;
> for (Binding binding : iterableOf(postOffice.getAllBindings())) {
> if (binding.getType() == BindingType.LOCAL_QUEUE) {
> total += ((LocalQueueBinding)
> binding).getQueue().getMessagesAdded();
> }
> }
> return total;
> }
> {code}
> This fails to give an accurate count if queues are being created or deleted
> (for example, as consumers disconnect or reconnect).
> This can easily be demonstrated by sending messages and then disconnecting
> all consumers (with queue auto-deletion) and seeing the "messages added"
> count drop to 0.
