[syslog-ng] Queue size in syslog-ng?

Hi all, In my setup, I send logs from all the servers to a central syslog server. This syslog-ng server also has a destination on a different port which is picked up by logstash's input block. (consider it just a consumer to those messages). What if this consumer goes down? How big is the queue? Is that configurable? How do I make sure that none of the messages are missed for the time the consumer is down? -- Cheers, Abhijeet R http://blog.abhijeetr.com
