[syslog-ng] Alternate logging destination

[Szeti, Balazs]

Hello!

I would like to design a centralized logging system with 50 edge nodes
and one center.
It's quiet important to have all the logs even if the center is
unreachable. Is there a way to configure syslog-ng to use an alternate
destination? For example if the centralized TCP destionation server is
down, the edge node syslog-ng may log in to a local file, so the logs
can be reached later manually. When the center server in online again
syslog-ng may log online again.

Any ideas?

Thanks in advance:
