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 It describes the outdated version 7, which was actively developed around 2014 and is considered dead by the rsyslog team.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Note that there is only limited rsyslog community support available for the outdated v7 version (officially we do not support it at all, but we usually are able to answer simple questions).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



Type: specific to immark input module

Default: 1200 (20 minutes)


This specifies when mark messages are to be written to output modules. The time specified is in seconds. Specifying 0 is possible and disables mark messages. In that case, however, it is more efficient to NOT load the immark input module.

So far, there is only one mark message process and any subsequent $MarkMessagePeriod overwrites the previous.

This directive is only available after the immark input module has been loaded.


$MarkMessagePeriod  600 # mark messages appear every 10 Minutes

Available since: rsyslog 3.0.0
