Sun GlassFish Enterprise Server v2.1.1 Administration Guide

Log Records

The Enterprise Server uses the Java EE platform Logging API specified in JSR 047. Enterprise Server logging messages are recorded in the server log, normally found at domain-dir/logs/server.log. When a log is rotated, Enterprise Server creates a new, empty file named server.log and renames the old file server.log_date, where date is the date and time when the file was rotated.

The components of the Enterprise 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.
