Hi,

Yes, you can do that with OSE. Which OSE version you need depends on how you want to send the logs to Splunk. For example, the http() destination referenced in the first blogpost needs a fairly recent version (at least 3.8 I think). Another (somewhat less sophisticated) option is to write the logs into files, and have Splunk to read those files - that can be done with older syslog-ng versions as well.

You can find links to recent packages at https://syslog-ng.org/3rd-party-binaries/

Hi Robert,

Great, thanks for coming back to me so quickly with very useful information. Can I just confirm that the OSE will support this, don’t need Premium or anything?

Many Thanks

Kind Regards

Stuart

Hi Stuart,

Although it is not explicitly mentioned in the docs (I should add a section sometime), syslog-ng can do this. You can find more details about it in these Splunk blogposts:

Hi

We are looking to collect logs from servers and devices in our DMZ and then filter the logs of unnecessary information to then be sent to our internal Splunk instance.

Would Syslog-ng OSE edition be capable of this task?

I’ve started to read through your excellent documentation for the OSE edition, I was wondering what route I should take to configure it for the scenario described above? The link I am thinking is correct is the “To configure syslog-ng OSE as a relay that receives log messages from client hosts and forwards them to a central logserver, see Procedure 4.2, Configuring syslog-ng on server hosts<https://www.balabit.com/sites/default/files/documents/syslog-ng-ose-latest-guides/en/syslog-ng-ose-guide-admin/html/configure-servers.html>.”

Does that sound correct?

Many Thanks

Kind Regards
