pri

Provides the undecoded PRI header value defined by RFC 5424 Section 6.2.1.

This property belongs to the Message Properties group.

Name:

pri

Category:

Message Properties

Type:

string

Description

Contains the raw PRI header value from RFC 5424 Section 6.2.1, which is written as <PRIVAL> in front of the syslog message. The integer inside the angle brackets encodes facility and severity per PRIVAL = facility * 8 + severity. Facilities 0 through 23 and severities 0 through 7 follow the tables in RFC 5424 (Tables 1 and 2). When rsyslog reads data without a syslog header, the PRI value is derived from input metadata or configuration so downstream templates can still compute facility and severity.

Usage

template(name="example" type="list") {
    property(name="pri")
}
