# Raindrops Middleware Input Plugin

This plugin collects statistics for [Raindrops middleware](http://raindrops.bogomips.org/Raindrops/Middleware.html) instances.

**Introduced in:** Telegraf v0.10.3
**Tags:** server
**OS support:** all

[raindrops]: http://raindrops.bogomips.org/Raindrops/Middleware.html

## Global configuration options <!-- @/docs/includes/plugin_config.md -->

In addition to the plugin-specific configuration settings, plugins support
additional global and plugin configuration settings. These settings are used to
modify metrics, tags, and field or create aliases and configure ordering, etc.
See the [CONFIGURATION.md](/telegraf/v1/configuration/#plugins) for more details.
