public interface PlatformLoggingMXBean extends PlatformManagedObject
There is a single global instance of the PlatformLoggingMXBean.
The ManagementFactory.getPlatformMXBean method can be used to obtain
the PlatformLoggingMXBean object as follows:
PlatformLoggingMXBean logging = ManagementFactory.getPlatformMXBean(PlatformLoggingMXBean.class);
The PlatformLoggingMXBean object is also registered with the
platform MBeanServer.
The ObjectName for uniquely
identifying the PlatformLoggingMXBean within an MBeanServer is:
java.util.logging:type=Logging
The instance registered in the platform MBeanServer with
this ObjectName implements all attributes defined by
LoggingMXBean.
| Modifier and Type | Method and Description |
|---|---|
String |
getLoggerLevel(String loggerName)
Gets the name of the log level associated with the specified logger.
|
List<String> |
getLoggerNames()
Returns the list of the currently registered
logger names.
|
String |
getParentLoggerName(String loggerName)
Returns the name of the
parent
for the specified logger.
|
void |
setLoggerLevel(String loggerName,
String levelName)
Sets the specified logger to the specified new
level.
|
getObjectNameList<String> getLoggerNames()
LogManager.getLoggerNames() and
returns a list of the logger names.String each of which is a
currently registered Logger name.String getLoggerLevel(String loggerName)
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.
loggerName - The name of the Logger to be retrieved.null. If the specified logger does not
exist, null is returned.Logger.getLevel()void setLoggerLevel(String loggerName, String levelName)
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.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.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").Logger.setLevel(java.util.logging.Level)String getParentLoggerName(String loggerName)
null is returned.
If the specified logger is the root Logger in the namespace,
the result will be an empty string.loggerName - The name of a Logger.null
is returned. Submit a bug or feature
