Tracing Broker to Producer Acks
Hi,
Is there any way for me to trace acks sent from broker to producer? Are there any configuration settings that I can set in log4j.properties?
Regards,
Ozan

Re: Tracing Broker to Producer Acks
Posted by Gary Tully <ga...@gmail.com>.
The "SENDING: Response ..." with the correlation id is enough, that is
the response to a sync request.
Ignore the "producer flow control" bit, that was just to determine the
context, I was not sure because the producerAck term has a specific
meaning in activemq. A producer does not typically get acks, just
responses to sync requests.

RE: Tracing Broker to Producer Acks
Posted by Ozan Seymen <Oz...@tdpg.com>.
Do you think I should rely on "SENDING: Response ..." line as the broker's guarantee or should I enable producer flow control and trace ProducerAcks?
I thought producer flow control was more to do with "resource management" and broker would always send some sort of persistence guarantee even producer flow control is disabled. Is this accurate?
Thanks for all this info Gary.

great.
One thought, it may be that the network connector is not requesting a sync send. It trys to respect the original client but in the case of a transacted client this may be a problem as messages are send async and batched at commit time.
Using a client side connection url parameter, jms.alwaysSyncSend=true would help validate if this is part of the problem as it would ensure each send is sync from the client.

RE: Tracing Broker to Producer Acks
Posted by Ozan Seymen <Oz...@tdpg.com>.
I am just interested in understanding when the broker assumed responsibility for a specific message. I will use this trace information to go in a bit deeper in my tests where I am loosing messages in some scenarios - like http://activemq.2283324.n4.nabble.com/Message-loss-in-network-of-brokers-transactional-send-td3588714.html#a3602343.
So basically I will repeat my tests with trace=true, pointpoint the exact location where the message is dropped and try to understand whether broker is killed before it assumed responsibility for it or not. If it hasn't assumed responsibility, then I will need to do something on the client code to trap that case (no need for a JIRA!).
PS: These messages are all persistent and should not be lost. That's why I am trying to trace "I've safely stored your message" response from broker to producer.

That is a response to the send request with responseRequired=true, note the correlationId = 13 which corresponds to the RECEIVED commandId=13.
So it confirms the receipt/store of the message.
A producerAck, used for flow control would be a separate request. Is that what you are interested in, producer flow control ?
