Actually if you enable the properties shown in gateway-log4j.properties and restart you should get request/response sizes in a separate access log but unfortunately not the authenticated/mapped user.  Keep in mind that the request length might be based on the request Content-Length header.  The code involved is in gateway-server/src/main/java/org/apache/hadoop/gateway/trace and AccessHandler.java in particular.

#log4j.logger.org.apache.hadoop.gateway.access=TRACE,httpaccess
#log4j.additivity.org.apache.hadoop.gateway.access=false

#log4j.appender.httpaccess=org.apache.log4j.DailyRollingFileAppender
#log4j.appender.httpaccess.File=${app.log.dir}/${launcher.name}-http-access.log
#log4j.appender.httpaccess.DatePattern=.yyyy-MM-dd
#log4j.appender.httpaccess.layout=org.apache.log4j.PatternLayout
#log4j.appender.httpaccess.layout.ConversionPattern=%d{ISO8601}|%t|%m%n

>  We make use of audit logs to capture each user how many transaction doing per hr per day. But we like to capture the details of how much bytes per transaction users are doing which will help us for various cases to manage Hadoop and Knox better. Any thoughts on this ?
