Dear syslog-ng users, This is the 113th issue of syslog-ng Insider, a monthly newsletter that brings you syslog-ng-related news. NEWS Why contribute to syslog-ng upstream? ------------------------------------- One of the returning questions I received recently: why contribute to the syslog-ng upstream? I guess it is a question many open-source projects receive regularly. There are many generic answers. Here I would like to focus more on syslog-ng, focusing on various parts of it. Of course, the generic answers also apply. Syslog-ng is an open-source project, free to use, modify, and extend. By contributing, you can give something back and improve syslog-ng for everyone. You do not have to be a developer in order to contribute: bug reports, configuration examples, PatternDB rules are all very useful contributions. https://www.syslog-ng.com/community/b/blog/posts/why-contribute-to-syslog-ng... Accelerating single TCP connections in syslog-ng: parallelize() --------------------------------------------------------------- One of the highlights of the syslog-ng 4.3.0 release is parallelize(). Normally, syslog-ng processes incoming messages from a TCP connection in a single thread. While this works fine with many connections, it is a bottleneck when using a single or very few high-traffic connections. Using parallelize() allows syslog-ng to process log messages from a single high-traffic TCP connection in multiple threads, thus increasing processing performance on multi-core machines. https://www.syslog-ng.com/community/b/blog/posts/accelerating-single-tcp-con... Backward compatibility in syslog-ng by using the version number in syslog-ng.conf --------------------------------------------------------- Many users are annoyed by the version number included in the syslog-ng configuration. However, it ensures backward compatibility in syslog-ng. It is especially useful when updating to syslog-ng 4 from version 3, but also when updating within the same major version. https://www.syslog-ng.com/community/b/blog/posts/backward-compatibility-in-s...
