Subject Re: traffic server usage / stats (clarification)

Thank you James. I took notice of
proxy.node.http.user_agent_total_request_bytes
and the others you noted but my /stat/ page is showing them as 0. I suppose
I turned to, and continue to be focused on, proxy.process.net.read_bytes
(and net.write) because they have a significant count --a number I would
more likely believe is a count of bytes served.
