Some questions about webclient?

[zenhox]

I have done all the install steps. When I run the reference topology in mininet. Then I saw the web client by click the index.html. My chrome open this html file and yean... I get the page. I get the topology, and some graphs. But I can't get the latency and on the plot, and the time is not updated. What's wrong is it? Another question is than where is the user interface. How can I get the latency data in format of text?
