Thanks Bobby for reply. However, I am aware of these things but my question different, when topology is not processing message still count on UI increases (Both on topology page/component page). Also, I have hardly seen the expected count of message processed on component page.

First of all there are several different modes on the UI. You can look at the metrics over different time periods, 10 mins, 3 hours, 1 day, and all time. If you have clicked on one of these links the page will display numbers for just this range, except in the section labeled for specific time periods. There is also a button that decides if we should include system stats or not. If this is selected the aggregate numbers will include acks. If it is not selected they will not. The other thing to be aware of is that trident is a layer that sits on top of storm so the UI displays what the trident topology was compiled down to, not as much of what your code looks like. Trident spouts actually run in a bolt, but control logic is in the actual spout. You can still pull out the number of messages that a trident spout emitted in most cases, but you need to know where to look, and you might need to click on the component page for the bolt running the spout to be able to divide the counts up by which stream they were written to. - Bobby On Monday, November 23, 2015 7:38 AM, Sachin Pasalkar <sachin_pasal...@symantec.com<mailto:sachin_pasal...@symantec.com>> wrote: Hi, We are developing the trident topology, we observed that the acking in UI increase continuously even though we do not process any message. I found description what those acks are https://github.com/miguno/kafka-storm-starter/issues/5. However, is there any plan to show users processed message? As a user, I am not interested in seeing these acks. I am very much interesting in acks for my messages. Thanks, Sachin
