Dear syslog-ng users,

This is the 113th issue of syslog-ng Insider, a monthly newsletter that brings you syslog-ng-related 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.

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.

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.
