There is no built in way right now. You would have to copy the time stamp in each stage in your topology. If you want to contribute something like that to storm it would be interesting.

I cannot enable the acking, hence complete latency is always 0. I am looking for other ways to measure end to end latency. Can we attach a timestamp when a tuple is emitted and check its end time in execute() method of my last bolt? I am trying to do this, but I do not see a way to attach timestamp to the tuple and send it further downstream. Any hints to measure the latency would be very helpful. Thanks. Best,Preethini
