The Administration Server log files record data about the server, including details about server access and the types of errors encountered during server operation.
The Access log records information about requests to and responses from the server. The Error log lists all errors that the server has encountered since the log file was created, and also contains informational messages about the server, such as when the server was started and who tried unsuccessfully to log in. By default, the access and server logs are located in install_dir/admin-server/logs.
For more information about the log files and their configuration, see the Sun Java System Web Server 7.0 Administrator’s Guide, and the online help that is available from the Admin console. You can also refer other books in the Web Server 7.0 documentation set.
