Hi All,
My name is Tibor Benke and I'm a participant of GSoC 2014. I wrote a state module for Salt which is able to generate syslog-ng configuration from YAML format. With this approach, you can deploy syslog-ng configurations simultaneously on thousands of computers based on their operating system or other parameters. It's in beta state, but the configuration generation works.
If you want to try it, you can find a HOWTO here:

And my blog here:
Regards,
Tibi
