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the heavily outdated version 5, which was actively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Note that there is no rsyslog community support available for this heavily outdated version.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.
Type: global configuration directive
Syslog messages frequently have the line feed character (LF) as the last character of the message. In almost all cases, this LF should not really become part of the message. However, recent IETF syslog standardization recommends against modifying syslog messages (e.g. to keep digital signatures valid). This option allows to specify if trailing LFs should be dropped or not. The default is to drop them, which is consistent with what sysklogd does.
