protocol-version

Carries the VERSION header field defined by RFC 5424 Section 6.2.2.

This property belongs to the Message Properties group.

Name:

protocol-version

Category:

Message Properties

Type:

string

Description

Contains the RFC 5424 Section 6.2.2 VERSION header field that signals which syslog message format the sender used. RFC 5424 assigns 1 to the standard defined in the specification and reserves future numbers for later revisions. When rsyslog consumes data without a native syslog header, this property reflects the configured or inferred version value for that input, commonly 1.

Usage

template(name="example" type="list") {
    property(name="protocol-version")
}
