I would like to know if it is possible to have load balancing for the syslog forwarding feature of Splunk. For exemple, is it possible to have something like the following in outputs.conf:
server = server1:514, server2:514
type = udp
Thank you in advance.
According to the documentation you should be able to do this, using the following syntax
defaultGroup = syslog:syslog_fwd_svr1, syslog:syslog_fwd_svr2
server = server1:514
server = server2:514
However, I have not tested this, nor can I guess how (or if) it will load balance messages.
Since its UDP, you should probably expect some level of duplication & inconsistency.
Side note: this feature is not available on Universal Forwarders
No, it is not possible to do that with a single port. You will need to designate a different port for server2.
