I have a number of related questions regarding the various message count attributes available.
On many of my high traffic queues Delivering size, Durable delivering size, and Durable persistent size appear to be large negative numbers like -188160082, even while the count is zero. Is that something to be concerned about, or something that I can reset to correct again? In a queue I'm looking at Acknowledge attempts matches the number of Messages added, but Messages acknowledged is a smaller number. The difference appears to be the number of Messages expired. What does that first statistic mean? Some of my queues have a Delivering Count less than 0, for example my DLQ which I have purged in the past (possibly from the other side of the mirror) has a Delivering count of -1989. A few other queues with negative counts are known to have slow consumers, and finally one with a core bridge has a negative count. If I can reproduce some of these scenarios is this a bug to be reported, and is there any consequence beyond the metrics? Finally, there's an operation resetAllMessageCounters() - does that just put all metrics at 0, so any in flight or queued messages end up reporting negative numbers again, or does it somehow trigger fresh calculations for the stats?
