Show numberOfMessagesVisible and numberOfMessagesNotVisible/InFlight

It would be nice if we can see the number of messages in each queue before clicking on it, because in the right side we'll only see the messages that aren't consumed yet. Wdyt?

(BTW tested the last changes and it's all good!)

That's a good point, I also thought about that, however it requires constantly polling all queues for that stats. I have concerns this would have major impacts on the usability and resource consumption.

[klutzer]

Yeah, you're right.

Maybe we can add a fetch button to each queue and just get the numbers when clicking the button. Or even a check-box so the user can select the queues to keep fetching just for them

[PacoVK]

I still fear that the numbers are eventually consistent and need tight polling. Do you really think that provides value? What would be the use case for selection on queues to get this metrics?

[klutzer]

I think will be very useful when we're monitoring a specific queue, so we can track the messages that are still in this queue but already in flight, like on AWS console.. For example the user implements some consumer and wants to be sure it reaches the right queue, without this option they will never see the messages on the right side because their application is consuming them before the UI

Right makes sense. Would be happy if you find time to provide a PR, otherwise i can look into it as soon as I find time 👍
