The #performance of #syslog_ng is not a #joke. However, some announcements are safer to be made on April 1st, just to make sure that people think before they expect 7 million EPS from a single syslog-ng instance in #production :-) Well, in a few years...

Last week I asked in a blog about #openssl 4 support and experiences:
https://www.syslog-ng.com/community/b/blog/posts/support-for-openssl-4-0
We received a detailed answer, and also a pull request to the #syslog_ng #GitHub repo. Of course, more investigation is needed, but syslog-ng now compiles with openssl 4 🤩

Each day I wear a random t-shirt from my 100+ collection of IT t-shirts. Today I'm wearing an @opensuse #conference t-shirt from 10 years ago. It was a fantastic reminder that the 2026 edition #CfP #deadline is today 😁

At the #BSidesBUD 2026 event, listening to the first talk. It's about #ransomware #negotiation. It's not my field of expertise, still it seems that I'd do the right decisions (if it was up to me). Being able to work in panic mode helps 😉

Although #OpenSSL 4.0 released just two weeks ago, the syslog-ng project has already received a #GitHub issue complaining that we do not support it. So, before we would allocate too much effort on it: what should we expect?

Almost 15 years ago, Balabit had a campaign, stating that #syslog_ng could process 650k messages a second. Now I am happy to present 7 #million #EPS (events per second). Timing the announcement to April 1 is not a coincidence :-) #AprilFoolsDay

Once I got hardware-accelerated #AI working under #Linux on my AI mini workstation from HP, my next goal was to make it easier to use. From this blog, you can read about my initial experiments with #OpenWebUI on @fedora Linux.

Ever since I bought my #AI mini #workstation from HP, my goal was to run hardware accelerated #ArtificialIntelligence workloads in a #Linux environment. Read more to learn how things turned out on #Ubuntu and @fedora !

@fedora My ultimate goal is to learn more about #ArtificialIntelligence in a #Linux environment, but the first thing I did after installation was trying #Steam and a couple of #games. Spoiler alert: installing #NeedForSpeed was smoother than on #Windows 😉

#UDP log collection is a legacy feature that does not provide security or reliability. You can improve its #reliability using #eBPF on #Linux in recent syslog-ng versions. Support for eBPF was added to Debian packages while preparing for syslog-ng 4.11.

A #question to #Instagram experts: why do I keep receiving "#Forward it us" and similar comments under the photos I publish? Anyone can see my photos without forwarding, just open:

If you want to test the new #Kafka source from the upcoming #syslog_ng release, there is now an easy way if you are on @opensuse / #SLES or @fedora / #RHEL (and compatibles). Just use my syslog-ng git snapshot repo:

Is there anyone still using #HDFS? Not just with #syslog_ng, but at all. I'm curious, as the HDFS destination is the last #Java-based driver in syslog-ng.
Nobody responded to my related posts for years, so 4.11 will be the last release to have it.

As a #music maniac I get into #Christmas mood by listening to some music. I have a collection of Hungarian folk songs, and also listen to #ELP's "I believe in Father Christmas".
Do you have any other non-mainstream song suggestions?

The December syslog-ng newsletter is now available on-line:

The August syslog-ng newsletter is now available on-line:
- Deprecating #Java-based drivers from syslog-ng: Is #HDFS next?
- Your first steps configuring #syslog_ng
- #Prometheus exporter in syslog-ng
-
While most #Java-based drivers have been deprecated in #syslog_ng years ago, we have recently removed all of them in preparation to syslog-ng 4.9.0. Right now, the only Java-based driver remaining is #HDFS, so we want to ask the syslog-ng community if the HDFS destination is still needed for them.
-
No response yet to my #syslog_ng #HDFS destination question:
Most likely it means that we can drop #Hadoop support from syslog-ng without any complaints. But I rather repeat my question a few more times on my #socialmedia accounts...

@shuLhan @cazabon Well, based on my experiences with #journald as a #syslog_ng guy, my expectation is that around 5-10 years of security nightmares are about to come with #run0:
https://www.syslog-ng.com/community/b/blog/posts/systemd-journald-vs-syslog-ng
Yes, a decade later after journald arrived, I have no problem recommending it. But the first 7-8 years were catastrophic both for users and developers.
-
Even if most people ask me to compare #systemd-#journald vs. syslog-ng, I would say that they complement each other. Combining the two gives you the most flexibility.

Last week I was on sick leave, but today I just finished building my syslog-ng git snapshot packages for @opensuse / #SLES & @fedora / #RHEL:
https://www.syslog-ng.com/community/b/blog/posts/rpm-packages-from-syslog-ng-git-head/
The #syslog_ng master branch mainly received bug fixes (including for #journald) and cosmetic changes.
