Welcome to Rsyslog
==================

`Rsyslog <http://www.rsyslog.com/>`_ is a **r**\ ocket-fast **sys**\ tem 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.
It supports, among others, :doc:`MySQL <tutorials/database>`,
:doc:`PostgreSQL <tutorials/database>`,
:doc:`failover log destinations <tutorials/failover_syslog_server>`,
ElasticSearch, syslog/tcp transport, fine grain output format control,
high precision timestamps,
queued operations and the ability to filter on any message part.
