# Input Plugins

Fluentd has 6 types of plugins: [Input](/0.12/input.md), [Parser](/0.12/parser.md), [Filter](/0.12/filter.md), [Output](/0.12/output.md), [Formatter](/0.12/formatter.md) and [Buffer](/0.12/buffer.md). This article gives an overview of Input Plugin.

## Overview

Input plugins extend Fluentd to retrieve and pull event logs from external sources. An input plugin typically creates a thread socket and a listen socket. It can also be written to periodically pull data from data sources.
