Sun GlassFish Enterprise Server v3 Administration Guide

About Logging

Logging is the process by which Enterprise Server captures information about events that occur during server operation, such as configuration errors, security failures, or server malfunction. This data is recorded in a log file, and is usually the first source of information when problems occur. Analyzing the log files can help you to determine the health of the server.

Although application components can use the Apache Commons Logging Library to record messages, the platform standard JSR 047 API is recommended for better log configuration.

The following topics are addressed here:

Log File

Enterprise Server log records are captured in the server log. The server log is named server.log by default and is typically located in domain-dir/logs. You can change the default name or location of the server log by using the Administration Console.

In addition to the server log, the domain-dir/logs directory contains the following additional logs:

When the server log reaches the specified size in bytes, the log is rotated and renamed with a timestamp name to server.log_date, where date is the date and time that the file was rotated. You can also rotate this log manually by following instructions in Rotating the Server Log.

Enterprise Server log records follow a uniform format:

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

An example log record might look like this:

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

The Administration Console presents log records in a more readable display.

Logger Namespaces

You can use the list-logger-levels(1) subcommand to list the existing loggers for the modules. Example loggers:
