Sun Java System Application Server 9.1 Administration Guide

Log Records

The Application Server uses the Java EE platform Logging API specified in JSR 047. Application Server logging messages are recorded in the server log, normally found at domain-dir/logs/server.log. When the server log reaches the specified size in bytes, the log is rotated and renamed to ogserver.log_date, where date is the date and time when the file was rotated.

The domain-dir/logs directory contains two other kinds of logs in addition to the server log. In the access subdirectory are the HTTP Service access logs, and in the tx subdirectory are the Transaction Service logs. For information about these logs, see Configuring Transactions.

The components of the Application Server generate logging output. Application components can also generate logging output.

Application components may use the Apache Commons Logging Library to log messages. The platform standard JSR 047 API, however, is recommended for better log configuration.

Log records follow a uniform format:

[#|yyyy-mm-ddThh:mm:ss.SSS-Z|Log Level|ProductName-Version|LoggerName|Key Value Pairs|Message|#]

For example:

system.core|_ThreadID=13;|CORE5004: Resource Deployed: 

In this example,

The log record format might be changed or enhanced in future releases.
