Tracking of message delivery, failed and success count.

[sanket-kulkarni-vmware]

How can I get message delivery tracking with help of this tool? I want to check how many messages are send and handled by the broker using this tool.

[boddumanohar]

same doubt here there a way to know if the message has been delivered or not? There is a way to specify QOS as 2 in the tool. But QOS 2 doesn't mean much if the broker could not be stable is there a way that this tool provide to know if the message has been actually delivered?
