Decodes the raw bytes as Vector’s native Protocol Buffers format.

This codec is experimental.

native_json

Decodes the raw bytes as Vector’s native JSON format.

This codec is experimental.

syslog

Decodes the raw bytes as a Syslog message.

Will decode either as the RFC 3164-style format (“old” style) or the more modern RFC 5424-style format (“new” style, includes structured data).

Outputs

<component_id>

Default output stream of the component. Use this component’s ID as an input to downstream transforms and sinks.

How it works

Context

By default, the redis source augments events with helpful context keys.

redis-rs

The redis source uses redis-rs under the hood, which is a high level Redis library for Rust. It provides convenient access to all Redis functionality through a very flexible but low-level API.

State

This component is stateless, meaning its behavior is consistent across each input.
