Well, I think you should log the subrequest being captured by your Lua code instead of your main location that is running your Lua code by enabling the standard log_subrequest directive in your subrequest's location and use an appropriate log_format setting.

See http://wiki.nginx.org/NginxHttpCoreModule#log_subrequest
