There's no such generic method, therefore I expect you mean setFileNamePattern from RollingPolicyBase for a RollingFileAppender. > But each thread is not logging in it's specific file and the output is > jumbled in different files.

Besides using some static variables, from my understanding this is by design, because one appender should always work the same in every instance it is used. An appender is just a name or logical container for some output behavior and I don't see why one and the same name or logical container or however you want to call it should behave differently under different contexts. Best practice in threaded environments is to use different loggers and appenders for each thread or Nested Diagnostic Contexts to differentiate log statements to the same logger for different threads. http://logging.apache.org/log4cxx/usage.html If different loggers per thread are to much configuration overhead for you, I would suggest configuring some template logger for every thread and programmatically create new loggers with new appenders for each thread based on the template logger. You would simply need to create new logger and appender objects using LOG4CXX API and provide most of the properties form the configured template logger and appender, just changing logger and file names to be specific for each thread.
