[syslog-ng] how to preserve original filenames when getting input from wildcard source

Hi all, New user, I have a very basic question about the wildcard source function that's been recently added to syslog-ng OSE: Suppose I'm getting input from the following: source s_files { wildcard-file( base-dir("/var/log/") filename-pattern("*.log") recursive(no) follow-freq(1) ); }; And in /var/log I have different *.log files: - 1.log - 2.log - 3.log ... How can I save the output on my syslog-ng server, so that input from 1.log would arrive in a file named 1.log on my server, input from 2.log in a file named 2.log etc.? Thanks and k ind regards, Wout
