About the Log4j configuration XML files

The primary log configuration is managed in portal-log4j.xml, which is packed inside the portal application file WEB-INF/lib/portal-impl.jar.

The file is in the standard Log4j XML configuration format, and allows you to:

Create and modify appenders
Bind appenders to loggers
Adjust the log verbosity of different classes/packages

By default, portal-log4j.xml specifies a log verbosity of INFO for the following packages:

com.endeca
com.endeca.portal.metadata
com.endeca.portal.instrumentation

It does not override any of the default log verbosity settings for other components.

Note: If you adjust the logging verbosity, it is updated for both Log4j and the Java Utility Logging Implementation (JULI). Code using either of these loggers should respect this configuration.
