Description (from rsyslog website)

RSYSLOG is the rocket-fast system for log processing.

It offers high-performance, great security features and a
modular design. While it started as a regular syslogd,
rsyslog has evolved into a kind of swiss army knife of
logging, being able to accept inputs from a wide variety
of sources, transform them, and output to the results to
diverse destinations.

RSYSLOG can deliver over one million messages per second
to local destinations when limited processing is applied
(based on v7, December 2013). Even with remote destinations
and more elaborate processing the performance is usually
considered "stunning".
