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 It describes the outdated version 7, which was actively developed around 2014 and is considered dead by the rsyslog team.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Note that there is only limited rsyslog community support available for the outdated v7 version (officially we do not support it at all, but we usually are able to answer simple questions).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.


The input object, as its name suggests, describes message input sources. Without input, no processing happens at all, because no messages enter the rsyslog system. Inputs are implemented via input modules.

The input object has different parameters:

  • those that apply to all input and are generally available for all inputs. These are documented below.
  • input-specific parameters. These are specific to a certain type of input. They are documented by the input module in question.

General Input Parameters

type <type-string>


The <type-string> is a string identifying the input module as given it each module’s documentation. For example, the UDP syslog input is named “imudp”.
