@priyank5485 Yes I see the tables don't get populated if lag responses are
empty, but we still end up with the div markup on the page. It seems that this
may be an area where other spouts could put their stats in the future. Could
you call the div topology-spout-stats, and put a comment in the html that says
it gets populated if stats are available?
