# app-name

Carries the APP-NAME header field defined in RFC 5424 Section 6.2.5.

This property belongs to the Message Properties group.

Name:

  app-name

Category:

  Message Properties

Type:

  string

## Description

Carries the `APP-NAME` header field defined in RFC 5424 Section 6.2.5, which identifies the originator application with up to 48 printable characters. RFC 5424 permits the NILVALUE (`-`) when an application cannot supply a value. When rsyslog receives events without a native syslog header (for example from imfile inputs or JSON payloads), this property reflects a configured default or an inferred placeholder instead of a transmitted header value.

## Usage

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