The management rules send notifications to the server log, but the logger for messages from the management rules subsystem itself is com.sun.enterprise.management.runtimetuner. By default, the log level for this logger is WARNING. To get more information from this logger, you must add a property to the configuration. The property name is com.sun.enterprise.management.runtimetuner and the value is FINE.
You can add this property on the Log Levels page in the Admin Console. For details, see the Admin Console online help.
You can also use the following asadmin set command to add this property. Substitute the name of the server instance or cluster for server. For example:
asadmin set server.log-service.module-log-levels.property.com\\.sun\\.enterprise\\.management\\.runtimetuner=FINE
For more information about the asadmin set command, see the Sun GlassFish Enterprise Server 2.1 Reference Manual.
