# structured-data

Provides the STRUCTURED-DATA field defined in RFC 5424 Section 6.3.

This property belongs to the Message Properties group.

Name:

  structured-data

Category:

  Message Properties

Type:

  string

## Description

Contains the `STRUCTURED-DATA` portion of a syslog message as defined in RFC 5424 Section 6.3. The field holds zero or more SD-ELEMENT blocks with ASCII SD-IDs and UTF-8 parameter values. When no structured data is present, RFC 5424 requires the NILVALUE (`-`). For events ingested without a syslog header, rsyslog populates this property with structured data derived from configuration or input metadata, if any.

## Usage

    template(name="example" type="list") {
        property(name="structured-data")
    }
