Dear syslog-ng users,

New performance tuning possibilities in syslog-ng

On April’s fool’s day, I shared that syslog-ng can reach 7 million EPS. This test lab result was in part possible thanks to a few performance enhancements coming to syslog-ng version 4.12. How 7 million EPS is possible? Before diving deeper, let me repeat it: 7 million EPS is just a lab testing result, not (yet) possible in the real world. However, the technologies enabling this are already available on the development branch of syslog-ng, or have been available for ages, just not tested or promoted enough.

Nightly syslog-ng containers based on Alma Linux

For many years, the syslog-ng project provided container images based on Debian. Most of our users run syslog-ng on RHEL & compatibles, and have asked for an RPM-based container. So, nightly containers based on Alma Linux are now also available. A while ago, I prepared a small test project to run syslog-ng in an Alma Linux container: https://www.syslog-ng.com/community/b/blog/posts/experimental-syslog-ng-container-image-based-on-alma-linux However, that was only an experiment which I never updated. Fast forward to today: nightly syslog-ng containers based on the latest syslog-ng git snapshot package builds are now available on the Docker Hub!

The status of OpenSSL 4.0 support in syslog-ng

OpenSSL 4.0 was released just over a month ago. So, how is its support progressing in syslog-ng? Well, Git master already supports it, and the patch is easy to backport to earlier releases. At the same time, version 4.12 will support OpenSSL 4.0 out of the box.
