Use this documentation with care! It describes the heavily outdated version 5, which was actively developed around 2010 and is considered dead by the rsyslog team for many years now.

This documentation reflects the latest update of the previously existing (now removed) v5-stable branch. It describes the 5.10.2 version, which was never released. As such, it contains some content that does not apply to any released version.

To obtain the doc that properly matches your installed v5 version, obtain the doc set from your distro. Each version of rsyslog contained the version that exactly matches it.

As general advise, it is strongly suggested to upgrade to the current version supported by the rsyslog project. The current version can always be found on the right-hand side info box on the rsyslog web site.

Note that there is no rsyslog community support available for this heavily outdated version. If you need to stick with it, please ask your distribution for support.

Welcome to 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. It supports, among others, MySQL , PostgreSQL, failover log destinations, syslog/tcp transport, fine grain output format control, high precision timestamps, queued operations and the ability to filter on any message part.
