Each application uses its own application logger to log messages. To configure the log level for a particular application, use one of two options:
In the Admin GUI Log Level configuration page add a property with a property name representing the logger name, and the value representing one of seven log levels (FINEST, FINER, FINE, CONFIG, INFO, WARNING, SEVERE) or OFF.
For example, to change the log level of application logger named com.X.Y to FINEST, the property name would be com.X.Y and the property value would be FINEST. The change is reflected in the domain.xml file, and takes effect immediately. No Server restart is required.
Directly add the property to the <module-log-levels\> element in domain.xml, as shown below.
<module-log-levels admin="INFO" classloader="INFO" cmp="INFO" cmp-container="INFO" configuration="INFO" connector="INFO" corba="INFO" deployment="INFO" ejb-container="INFO" javamail="INFO" jaxr="INFO" jaxrpc="INFO" jdo="INFO" jms="INFO" jta="INFO" jts="INFO" mdb-container="INFO" naming="INFO" node-agent="INFO" resource-adapter="INFO" root="INFO" saaj="INFO" security="INFO" server="INFO" synchronization="INFO" util="INFO" verifier="INFO" web-container="INFO"\> <property name="com.X.Y" value="FINEST" /\> </module-log-levels\>
