WebLogic: The Definitive Guide

HTTP Access Logs

HTTP access logs maintain a record of all HTTP requests received by WebLogic Server. You can separately configure HTTP logging for each web server or virtual host defined in your WebLogic domain. The information in the access logs may be written in one of two formats: either the Common Log Format or the Extended Log Format. The Common Log Format is the default format based on standard conventions. The Extended Log Format enables you to customize the information that is recorded in the access logs.

To configure the HTTP logging facilities for a web server, start the Administration Console, then go to the Servers node in the left frame and choose the Logging/HTTP tab. To configure logging for a virtual host, select the host from the Services/Virtual Hosts node and then choose the Configuration/Logging tab. Note that the logging facilities also include a “log rotation” mechanism, which means that WebLogic Server continues to use a log file until its size reaches a certain limit or for a certain time period. After that, WebLogic renames the log file and creates a new one in its place. Table 3-4 provides a description of the configuration settings for the HTTP logging facility.
