Fluent Bit MySQL Output Plugin

This is plugin for Fluent Bit, an open-source data collector that can be used to collect, process, and forward logs and metrics data. This plugin allows you to write data to a MySQL database. It's influenced by the PostgreSQL output plugin for Fluent Bit and the MySQL Fluentd plugin.

Usage

Download the last release and add to your plugin directory, example:

curl -o /fluent-bit/etc/mysql-output-plugin.so https://github.com/gabrielbussolo/fluent-bit-mysql-output-plugin/releases/download/v0.1.0-alpha/mysql-output-plugin.so

Create a file to register the custom plugin (if you don't have one already):

plugins.conf:

[PLUGINS]
    Path /fluent-bit/etc/mysql-output-plugin.so

Add the configs to your fluent-bit.conf:

Key	Description	Default
Address	The address of the MySQL server	localhost:3306
User	The user to connect to the MySQL server	root
Password	The password to connect to the MySQL server	-
Database	The database to connect to	-
Table	The table to connect to	-

example:

# import the plugin
[SERVICE]
    Flush           1
    Log_Level       info
    plugins_file    /fluent-bit/etc/plugins.conf

# configure the plugin    
[OUTPUT]
    Name mysql
    Address localhost:3306
    User root
    Password my-secret-pw
    Database fluent_bit
    Table test

Is expected that the table already exists in the database with the following fields data, datetime and tag. The data field is a json type, the datetime field is a datetime and tag a varchar.

Example:

create table fluent_bit.test
(
    id       int auto_increment
        primary key,
    data     json         null,
    datetime datetime     null,
    tag      varchar(100) null
);

Next steps:

• Add support to create a default table if it doesn't exist
• Support async writes
• Add options for the connection pool
• Implement CI/CD
