NEWS Automatic configuration of the syslog-ng wildcard-file() source Reading files and monitoring directories became a lot more efficient in rec= ent syslog-ng releases. However, it is also needed manual configuration. Ve= rsion 4.11 of syslog-ng can automatically configure the optimal setting for= both. https://www.syslog-ng.com/community/b/blog/posts/automatic-configuration-of= -the-syslog-ng-wildcard-file-source What to fix next in syslog-ng? Version 4.11 of syslog-ng will feature a brand-new Kafka source. While it i= s being tested and reviewed, we are working on reducing the number of open = issues. What should be fixed next? https://www.syslog-ng.com/community/b/blog/posts/what-to-fix-next-in-syslog= -ng UDP reliability improved in syslog-ng Debian packaging UDP log collection is a legacy feature that does not provide any security o= r reliability, but is still in wide use. You can improve its reliability us= ing eBPF on Linux in recent syslog-ng versions. Support for eBPF was added = to Debian packages while preparing for the 4.11.0 syslog-ng release. https://www.syslog-ng.com/community/b/blog/posts/udp-reliability-improved-i= n-syslog-ng-debian-packaging WEBINARS * You can learn about upcoming webinars and browse recordings of past webinar= s at https://www.syslog-ng.com/events/ Your feedback and news, or tips about the next issue are welcome.
