logging all linux logs to syslogs ng for heavy forwarder

Hello All, I need to send all the LOG files from the client on to the server which is running syslog NG. now whats working for me is all the client logs gets written on the server on to the file that i have mentioned on the syslog conf. But I am wondering now for instance lets say i am not interested in syslog and i am only interested in Apache, messages, dmesg, auth logs etc how do i write the logs different logs on to different files on the syslog machine. So that the final output on Syslog NG server will be /var/log/syslog getting only syslog logs, /var/log/http receiving all the Apache logs etc etc etc and not jumbled up into one single file. Thanks
