URCap log details

Hi All,
I want to do same thing.
I failed to configure poliscope logging to file. How to do it?
I pasted below text to ./urcontrol/gui.properties:
LogAppenders=com.ur.util.logging.ConsoleAppender com.ur.util.logging.FileAppender
LengthOfLogInMemoryBeforePersist=100
LogLevel=DEBUG

How to do it? And how to change default directory for this log?
Its described in any document?

My task is to collect UR logs (Poliscope) in real time and send it to cloud.
Data in log files is not latest, if I compare to poliscope gui.
