# procid

Carries the PROCID header field defined in RFC 5424 Section 6.2.6.

This property belongs to the Message Properties group.

Name:

  procid

Category:

  Message Properties

Type:

  string

## Description

Carries the `PROCID` header field defined in RFC 5424 Section 6.2.6. The field has no fixed syntax; senders often use it for a process name, PID, transaction identifier, or other origin-specific token, and RFC 5424 allows the NILVALUE (`-`) when no value applies. When rsyslog ingests messages without a syslog header, this property holds the configured or inferred value for the source instead of a transmitted header field.

## Usage

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