Defaults to 30. + * :queue-name — only gather statistics for this queue name. Defaults to nil, meaning all queues. + + Example return value: + {:queue-a {:ok 100, :retries 2, :retry-percentage 2.0} + :queue-b {:ok 100, :retries 75, :retry-percentage 75.0}} + + From the example value above, we can see that :queue-b fails at a much higher rate than :queue-a. + Assuming that the queue consumers are correctly implemented, this means that the service representing :queue-b + is much more unstable than the one representing :queue-a.
