1. Declare the name of the syslog server:

   destination syslog_server { udp(log.server.my.com); };
   	      

2. Make the system log to the syslog server:

   log { source(src); destination(syslog_server); }; 
   	      

   Make sure to put this at the top of the list of “log” statements, before any statements that carry “final” flags.

Restart the daemon: /etc/init.d/syslog-ng restart

If you have a server running already, you can now test the configuration by logging on to the client and saying something like: echo "JohnDoe testing Syslog-NG" | logger

You should see the message turn up in the log files of the server.
