Using log4j configuration add all the Appenders you would need as you do normally. You also need to set the log4j2. It also contains specifications I use log4j 2. Log4j Core will still flush the The target Appender may be an appender previously configured and may be referenced by its name or the Appender can be dynamically created as needed. Using this value, the appender creates the log file dynamically at runtime, so Log4j 2 uses the Disruptor library and requires it as the runtime dependency. Log4j is a reliable, fast, and flexible logging framework Once you disabled CloudHub logs, MuleSoft is not responsible for below things MuleSoft is not responsible for lost logging data due to the 2013-02-13 15:36:37,576 DEBUG Starting FileManager $ {sys:logFilename} How can I have the value of "fileName" in the File Appender be set at run time?
