Date: 2014mar11 Product: Jetty Q. What is the format of Jetty request log? And how can I change it? A. The request log is in <jetty-home>/logs/YYYY_MM_DD.request.log A typical line looks like this:

127.0.0.1 - - [11/Mar/2014:14:11:17 +0000] "GET /mysite/mypage.ext HTTP/1.1" 200 1800

The fields are the:

<host> <user-logname> <authuser> [<timestamp>] "<method> <uri> <protocol>" <status-code> <bytes>

This is NCSA format http://www.w3.org/Daemon/User/Config/Logging.html#common-logfile-format The format is partly configured in <jetty-home>/etc/jetty-requestlog.xml There are some options in there - eg filenameDateFormat, retainDays, extended. They are the easy way to make changes. If you want to radically change something, the class that makes the log is that file. By default it is: org.eclipse.jetty.server.NCSARequestLog But you can make your own class.
