empty `deliveries` value (RMQ v3.5.0) about rabbitmq-management

[michaelklishin]

So you are sure that you have a flow of messages to the consumers on queue {queue-name}?

[bosr]

It's a small flow (1 per minute approx) but yes we do have messages on that queue being consumed by the consumer.

Well, this means in the last N seconds there are no stats to show.

With a 100 messages a second rate, I get

So message rates haven't disappeared in 3.5.0, it's just an interesting case with default retention policies and message rates of "lower than 1 per minute". Please see Retaintion policies, too.

Arguably we should return values as zeros but this may be less trivial than it sounds.

[bosr]

Thanks Michael, I'm commuting right now. I see your 'deliveries' is an empty list too. It used to have message stats per consumer, right?

You upgraded from 3.3.x or earlier? We don't gather those stats by default any more. See the description of rates_mode at http://www.rabbitmq.com/management.html#fine-stats for how to turn them on.

[bosr]

Thanks !
