String template type¶

Uses a single template string mixing constants and replacement variables. Best suited for textual output with simple manipulation needs. .. summary-end

String templates closely resemble the legacy $template statement. They have a mandatory parameter string which holds the template string to be applied. The string mixes constant text and replacement variables processed by the property replacer.

Example:

template(name="tpl3" type="string"
         string="%TIMESTAMP:::date-rfc3339% %HOSTNAME% %syslogtag%%msg:::sp-if-no-1st-sp%%msg:::drop-last-lf%\n"
        )

The text between percent signs is interpreted by the property replacer, which reads message properties and applies options for formatting and processing.
