[syslog-ng] Question about PE edition disk-based buffering

[Balint Kovacs]

Hi Clayton,

the failover time is steered by the time_reopen() global option (60 sec 
by default), so setting it to a much lower value should do the trick.

 From the admin guide:
"To list several failover servers, separate the address of the servers 
with comma. The time syslog-ng PE waits for the a server before 
switching to the next failover server is set in the /|time_reopen()|/ 
option. For details about how client-side failover works, see Section 
2.15, Client-side failover 
<http://www.balabit.com/sites/default/files/documents/syslog-ng-pe-v4.0-guide-admin-en.html/index.html-single.html#concepts_failover>."

http://www.balabit.com/sites/default/files/documents/syslog-ng-pe-v4.0-guide-admin-en.html/index.html-single.html#example-failover-server-tcp

I assume that the TCP connection breakdown is detected by syslog-ng in a 
timely manner, pls correct me if I misunderstood the problem.
