Java Logging: LogManager
java.util.logging.LogManager manages the internal
Logger hierarchy, and
initiates the configuration of the
Logger's, either through the configuration
class or configuration file.
There is only a single
LogManager instantiated in the whole JVM. It is a singleton,
in other words. Here is how to obtain the
LogManager manager = LogManager.getLogManager();
You will not often need to interact directly with the
LogManager, except for
a few borderline cases.
For instance, if you want to reload the configuration file, you can do so using either of these methods:
The first method on the
LogManager simply re-reads the configuration from file (or class), in
case these has changed.
The second method on the
LogManager simply reads the configuration from the given
You can also get access to an MXBean (Java Management Extensions) from the
using the method
getLoggingMXBean(). Here is an example:
LoggingMXBean mxBean = logManager.getLoggingMXBean();
LogManager has more methods than these two, but most often you will not need them.
