Sun GlassFish Enterprise Server 2.1 High Availability Administration Guide

Configuring Log Messages

The load balancer plug-in uses the web server’s logging mechanism to write log messages. The default log level is set to the default logging level on Sun Java System Web Server (INFO), Apache Web Server (WARN) and Microsoft IIS (INFO). The log levels, FINE, FINER, and FINEST, map to the DEBUG level on the web server.

These log messages are written to the web server log files, and are in the form of raw data that can be parsed using scripts, or imported into spreadsheets to calculate required metrics.
