The Maintenance and Usage Server processes use Jakarta Log4j by the Apache Software Foundation for logging. Each process requires its own log configuration file, although each configuration file contains the same settings.
The files, log4j_maintenance.cfg and log4j_usage.cfg, are located in the \ondemand directory on the same server volume as the Maintenance and UsageServer processes. Using the configuration settings in the files, you can set the logging information level (INFO, WARN, ERROR, FATAL, and DEBUG) and determine the output method (screen, rolling log file, and so forth).
The files contain brief descriptions of the configuration settings. For more information about the configuration settings, see the Jakarta Log4j Web site.
