The complete latency for the topology and spout is always coming zero. Also acker is coming zero. The number of acked for bolts are coming fine. I am using storm 1.1.1. My topology is reading text file and classifiying text using Naive Bayes in distributed environment of Apache storm.

I think you need to anchor the tuples in order to be able to track the latency:
