Rsyslog is an enhanced multi-threaded syslogd.
Among others, it offers support for on-demand disk
buffering, reliable syslog over TCP, writing to
databases (MySQL, PostgreSQL, Oracle, and many
more), email alerting, fully configurable output
formats (including high-precision timestamps), the
ability to filter on any part of the syslog
message, on-the-wire message compression, and the
ability to convert text files to syslog. It is a
drop-in replacement for stock syslogd and able to
work with the same configuration file syntax.

Changes:
Native TLS for plain TCP syslog is now supported. This is the world's first implementation of the upcoming syslog-transport-tls IETF standard. The RFC 3195 input has been changed to a module and was re-integrated into the normal build. A runtime system has been separated from the main rsyslogd. The networking subsystem has been rewritten to support an extensible network stream driver interface.
