Subject Re: How to maintain an historical view of queue contents?

Re AMQ-1648; it would be ideal to avoid as much as possible having to
evict/lose messages, because a queue or some other system resource has
reached its max capacity. Instead, you'd like to proactively monitor system
resources and invoke or trigger some action (e.g., whenever a resource
reaches a predefined threshold) that can alleviate the situation and thus
avert losing messages. Check out

AMon . It gives you that facility to  do just that.
