getFullQueryLoggerOptions

stop

public void stop()

reset

public void reset(java.lang.String fullQueryLogPath)

Need the path as a parameter as well because if the process is restarted the config file might be the only location for retrieving the path to the full query log files, but JMX also allows you to specify a path that isn't persisted anywhere so we have to clean that one as well.

isEnabled

public boolean isEnabled()
