The management interface for the logging facility. 
java.lang.management.PlatformLoggingMXBean is the management interface for logging facility registered in the 
platform MBeanServer. It is recommended to use the PlatformLoggingMXBean obtained via the 
ManagementFactory.getPlatformMXBean(PlatformLoggingMXBean.class) method. 
Author: Ron Mann,  Mandy Chung
See Also:
  • PlatformLoggingMXBean
Deprecated:LoggingMXBean is no longer a platform MXBean and is replaced with PlatformLoggingMXBean. It will not register in the platform MBeanServer. Use ManagementFactory.getPlatformMXBean(PlatformLoggingMXBean.class) instead.
Since:  1.5

Returns the list of currently registered logger names. This method calls LogManager.getLoggerNames and returns a list of the logger names. 
Returns:A list of String each of which is a currently registered Logger name.
/**

     */
    public java.util.List<String> getLoggerNames();

    
Gets the name of the log level associated with the specified logger. If the specified logger does not exist, null is returned. This method first finds the logger of the given name and then returns the name of the log level by calling: 
 Logger.getLevel().getName(); 


 If the Level of the specified logger is null, which means that this logger's effective level is inherited from its parent, an empty string will be returned. 
Params:
  • loggerName – The name of the Logger to be retrieved.
See Also:
Returns:The name of the log level of the specified logger; or an empty string if the log level of the specified logger is null. If the specified logger does not exist, null is returned.

    public String getLoggerLevel(String loggerName);

    
Sets the specified logger to the specified new level. If the levelName is not null, the level of the specified logger is set to the parsed Level matching the levelName. If the levelName is null, the level of the specified logger is set to null and the effective level of the logger is inherited from its nearest ancestor with a specific (non-null) level value. 
Params:
  • loggerName – The name of the Logger to be set. Must be non-null.
  • levelName – The name of the level to set on the specified logger, or null if setting the level to inherit from its nearest ancestor.
Throws:
  • IllegalArgumentException – if the specified logger does not exist, or levelName is not a valid level name.
  • SecurityException – if a security manager exists and if
the caller does not have LoggingPermission("control").
