Forward

Forward is the protocol used by Fluent Bit and Fluentd to route messages between peers. This plugin implements the input service to listen for Forward messages.

Configuration Parameters

The plugin supports the following configuration parameters:

Getting Started

In order to receive Forward messages, you can run the plugin from the command line or through the configuration file:

Command Line

From the command line you can let Fluent Bit listen for Forward messages with the following options:

$ fluent-bit -i forward -o stdout

By default the service will listen an all interfaces (0.0.0.0) through TCP port 24224, optionally you can change this directly, e.g:

$ fluent-bit -i forward://192.168.3.2:9090 -o stdout

In the example the Forward messages will only arrive through network interface under 192.168.3.2 address and TCP Port 9090.

Configuration File

In your main configuration file append the following Input & Output sections:

[INPUT]
    Name              forward
    Listen            0.0.0.0
    Port              24224
    Buffer_Chunk_Size 32KB
    Buffer_Max_Size   64KB

[OUTPUT]
    Name   stdout
    Match  *

Testing

Once Fluent Bit is running, you can send some messages using the fluent-cat tool (this tool is provided by Fluentd:

$ echo '{"key 1": 123456789, "key 2": "abcdefg"}' | fluent-cat my_tag

In Fluent Bit we should see the following output:

$ bin/fluent-bit -i forward -o stdout
Fluent-Bit v0.9.0
