How to Configure the Web Connector from metrics.log Values
Richard, I realize your question here is from 2014, and perhaps you have since resolved it, but I suspect your problem was that the port set in the CF admin (below the "metrics log" checkbox) was set to 8500, which is your internal web server (used by the CF admin only, typically, if at all). That's why the numbers are not changing. (And for those who don't enable the internal web server at installation of CF, or later, most values in the metrics log are null).
I address this problem in a blog post I happened to do just last week: http://www.carehart.org/blog/client/index.cfm/2016/3/2/cf_metrics_log_part1
Hope any of this helps.
