Use this documentation with care! It describes
the outdated version 7, which was actively
developed around 2014 and is considered dead by the
rsyslog team.
This documentation reflects the latest update of the
v7-stable branch. It describes the 7.6.8 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
v7 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 only limited rsyslog community support
available for the outdated v7 version (officially we do not
support it at all, but we usually are able to answer simple
questions). If you need to stick with v7, it probably is
best to ask your distribution for support.
Message Modification Modules¶
Message modification modules are used to change the content of messages being processed. They can be implemented using either the output module or the parser module interface. From the rsyslog core’s point of view, they actually are output or parser modules, it is their implementation that makes them special.

- mmcount
- Fields Extraction Module (mmfields)

- Log Message Normalization Module
