Motivation
I wanted to know what the access log format was so I could parse and label the fields correctly in my centralized logger. Ex:
I had to read the code to see what the different values were. https://github.com/containous/traefik/blob/5acd43efaf076ae2204285e750e41976c29069f2/middlewares/accesslog/logger_formatters.go#L34
