What do some of the fields returned from ActiveMQ.Agent query mean?

Question

I'm trying to do some kind of administration on our activemq process, and I'd like to know what some of the fields mean that I get back.

Specifically,

What is InFlightCount? Is that the number of messages that the producer has sent but not What is AverageEnqueueTime measured in? Seconds? What are EnqueueCount and DequeueCount? What is DispatchCount?

Answer 1

Quoting from here:

InFlightCount: The number of messages that have been dispatched and are currently awaiting acknowledgment from the consumer. So as this number decreases, the DequeueCount increases.

AverageEnqueueTime: On average, the amount of time (ms) that messages remained enqueued. Or average time it is taking the consumers to successfully process messages.

EnqueueCount: The number of messages that have been written to the queue over the lifetime of the queue.

DequeueCount: The number of messages that have been successfully (i.e., they’ve been acknowledged from the consumer) read off the queue over the lifetime of the queue.

DispatchCount: The number of messages that have been dispatched (sent) to the consumer over the lifetime of the queue. Note that dispatched messages may not have all been acknowledged.

Candiru, can you tell us if you know the source of this information? Or is it only on the email? – Northamptonshire

Answer 2

Some points are not matching my observation. One thing is dequeue count; I noticed that

dequeue = expired + dispatched

So dequeue = removed from queue by any reason(expired or dispatched); it does not necessarily mean acked; it's just "number of messages removed from the queue by any reason"; if expired, there's should not be ack, ofc.

Even doc of ActiveMQ does not match what I saw.
