What is Rsyslog?

Rsyslog is a 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 the results to diverse destinations.

Rsyslog has a strong enterprise focus but also scales down to small systems.
