[syslog-ng] High availabilty configuration

[Fabien Wernli]

Hi,

I was considering a config-based solution: have all clients send to multiple
syslog-ng servers (e.g. using multicast), after adding a unique identifier
to each message (e.g. using the uuid template function).

Then have all syslog aggregators ship their copy to a common storage, the
unique key enabling you to identify/drop the multiple copies of the same message,

Cheers
