Hi Laci, Elaaticsearch is not limited by any means regarding indexable traffic. Should you need any real life example then have a look at my blog: https://balagetech.com/tag/elasticsearch/ This page will show you the feature differences between different licenses: https://www.elastic.co/subscriptions Note that the free version does not have AD integration. (Maybe you could put a WAF before Kibana, or handling the AD integration with Apache + LDAP) ps: I am not paid by anyone to suggest Elasticsearch. It is simply a tool I use.

Thanks for the answers. So, I definitely need an onprem solution and yes, Elastic is a good idea, however based on my previous research even the OS version is restricted to some amount of daily log. Maybe I'm wrong and in this case I may give a try again. At this point I don't know how much logs will I ingest daily but because it is more than 30K devices including core routers, firewalls and all sort of servers, I don't think any traffic limited solution will be sufficient.
Graylog is a very good solution which I already tested but the "free" version is limited to something like 50 Mbyet per day.
I'll check this onion thingy, thank you Peter for the heads up

Hi,
These are not my personal experiences, but talking to thousands of syslog-ng users at different events:
- Many are happy with grep and hate anything with a GUI. It works relatively well, if you have many small log files (separated by date, host, application, etc.), but if you have lots of logs, you can't avoid message parsing and indexing for efficient search. - Splunk is one of the most popular destinations with syslog-ng. OSE users tend to use the free version, which can index up to 500MB of logs a day. - Elasticsearch is the other most popular destination. With the latest version most of the security features are included in the open source version for free, so it does not need 3rd party extensions or a commercial license any more. - Graylog is also getting popular among syslog-ng users. We can feed it with structured log messages in multiple ways: either GELF or JSON. Free, open source, but commercial extensions and support are available. - I did not test recently, but Security Onion is a nice security analytic platform which also includes log management with analysis, dashboards, etc. It's free, open source, but commercial support is available. - Logzilla is focused on Cisco network devices and automation but also works for generic log management. It is commercial software, but a free version is also available.
Of course any time indexing and GUI are involved you need some extra hardware compared syslog-ng, so definitely more expensive even if you go with the free versions.

Hi,
Our new central syslog collect&store system are almost complete and finally it is based on Syslog-ng OSE. The only issue I want to solve, is how to present those logs to the users. Originally I thought it would be enough if they will get the directories as NFS exports and they can use their favourite grep to search files, but I thought maybe I can implement some more user friendly solution.
In the planning phase of the project, I've tested various solutions including Graylog, ELK and of course I'm aware of the beauty of SSB :) , but all of these solutions are too expensive for this project.
Then I thought maybe if I forward the logs to some database (SQL or noSQL) I can try to find some very simple frontend for that DB provides a simple search interface for those logs. Nothing fancy is required, but AD auth should be an option.
I'm sure I'm not the only one facing this issue, so I hope someone in the community can share some previous experience on this
Thanks Vlad

It's not. By all means grab the -oss packages, they don't contain any non-free code.

Currently we are not sending SNI extension in the Client Hello message. However, I made a PR to implement this: https://github.com/balabit/syslog-ng/pull/2930
Can you build syslog-ng from source? It would be great, if you tested the PR.

Hi,
I am using TLS over TCP connection to forward my syslog events to a remote server. My remote server uses SNI (Server Name Identification) to route connections/events to one of the available backend servers.
I observe that syslog-ng doesn't send SNI during TLS handshake.
How can I enable it?
My configuration is as follows:
=================================== source s_net { syslog(transport(udp) port(1514)); }; destination d_tcp { tcp( "XX.example.net <https://nam05.safelinks.protection.outlook.com/?url=http%3A%2F%2FXX.example.net&data=02%7C01%7Cattila.szakacs%40oneidentity.com%7Cf01aaae6998d42d90aa908d73b3d6e1a%7C91c369b51c9e439c989c1867ec606603%7C0%7C1%7C637043007358265020&sdata=sTv8kJpxK%2FDNONaBFcNArgPiZ8ZbBFuyIHKwfL1Yn7w%3D&reserved=0> " port(96) tls( peer-verify(required-untrusted) ca_dir("/etc/syslog-ng/ssl")
key-file("/etc/syslog-ng/ssl/globaltest/XX.example.net.key.pem")
cert-file("/etc/syslog-ng/ssl/globaltest/XX.example.net.cert.pem") ) ); }; log { source(s_net); destination(d_tcp); }; ===================================
I want syslog-ng to send XX.example.net <https://nam05.safelinks.protection.outlook.com/?url=http%3A%2F%2FXX.example.net&data=02%7C01%7Cattila.szakacs%40oneidentity.com%7Cf01aaae6998d42d90aa908d73b3d6e1a%7C91c369b51c9e439c989c1867ec606603%7C0%7C1%7C637043007358275016&sdata=ugyIt85VhK6%2FEoZVAJ%2B2gLnPfr7M5n2%2FMHqR0hcuGto%3D&reserved=0> as SNI to my remote server
Please advise
