Github user roshannaik commented on the issue: https://github.com/apache/storm/pull/2289 @revans2 sorry missed your msgs from here. - Yes would be nice to have the actual latency (as reported in UI) to also be included here. I also run TVL in modes where the topology cant keep up. i have been having to collect it separately. can report 0 latency if ACKer is disabled. - I often copy and paste these csv results into excel for easy viewing. So the csv results with decimals limited to 3 digits would be nice. Unless the decimals after 3 digits is useful for machine readable not that many decimal places even for machine readable - One usability improvement would for the tool *tee* whatever it is printing into the report onto the console as well. helps in multiple ways.
