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 It describes the heavily outdated version 5, which was actively developed around 2010 and is considered dead by the rsyslog team for many years now.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Note that there is no rsyslog community support available for this heavily outdated version.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.


In most cases, people install rsyslog either via a package or use an “official” distribution tarball to generate it. But there may be situations where it is desirable to build directly from the source repository. This is useful for people who would like to participate in development or who would like to use the latest, not-yet-released code. The latter may especially be the case if you are asked to try out an experimental version.
