Rsyslog is a Rocket-fast SYStem for LOG processing. It offers high performance, great security features, and a modular design. While it began as a regular syslogd, rsyslog has evolved into a Swiss Army knife of logging, able to accept inputs from a wide variety of sources, transform them, and output the results to diverse destinations.

Rsyslog can deliver over one million messages per second to local destinations when limited processing is applied. Even with remote destinations and more elaborate processing, the performance is usually considered “stunning.”
