StatusLoggerAdmin

public StatusLoggerAdmin(String contextName,
                         Executor executor)

Constructs a new StatusLoggerAdmin with the Executor to be used for sending Notifications asynchronously to listeners.

Parameters:

contextName - name of the LoggerContext under which to register this StatusLoggerAdmin. Note that the StatusLogger may be registered multiple times, once for each LoggerContext. In web containers, each web application has its own LoggerContext and by associating the StatusLogger with the LoggerContext, all associated MBeans can be unloaded when the web application is undeployed.

executor - used to send notifications asynchronously
