  1. Output Plugins

TCP & TLS

The tcp output plugin allows to send records to a remote TCP server. The payload can be formatted in different ways as required.

Configuration Parameters

Key

Description

default

Host

Target host where Fluent-Bit or Fluentd are listening for Forward messages.

127.0.0.1

Port

TCP Port of the target service.

5170

Format

Specify the data format to be printed. Supported formats are msgpack json, json_lines and json_stream.

msgpack

json_date_key

Specify the name of the date field in output

date

json_date_format

Specify the format of the date. Supported formats are double , iso8601 (eg: 2018-05-30T09:39:52.000681Z) and epoch.

double

TLS Configuration Parameters

The following parameters are available to configure a secure channel connection through TLS:

Key

Description

Default

tls

Enable or disable TLS support

Off

tls.verify

Force certificate validation

On

tls.debug

Set TLS debug verbosity level. It accept the following values: 0 (No debug), 1 (Error), 2 (State change), 3 (Informational) and 4 Verbose

1

tls.ca_file

Absolute path to CA certificate file

tls.crt_file

Absolute path to Certificate file.

tls.key_file

Command Line

$ bin/fluent-bit -i cpu -o tcp://127.0.0.1:5170 -p format=json_lines -v

Start the TCP listener

Run the following in a separate terminal, netcat will start listening for messages on TCP port 5170

$ nc -l 5170

Start Fluent Bit

$ bin/fluent-bit -i cpu -o stdout -p format=msgpack -v
