We started looking for other solutions. There were a few possible alternatives to msyslog with some nice features (. rsyslog, syslog-ng, etc), but none of them qualified. Most of them were still single threaded, syslog oriented without native support for MS Windows, in addition to awkward configuration syntax, ugly source-code and so on. So I decided that it would be easier for us on the long term to design and write nxlog from scratch instead of hacking something else. Thus nxlog was born in 2009 and has been a closed source product heavily used in several production deployments since. The source code of NXLOG Community Edition was released in November 2011.
