# Swap Input Plugin
|
|
|
|
The swap plugin collects system swap metrics. This plugin ONLY supports Linux.
|
|
|
|
For more information on what swap memory is, read [All about Linux swap
|
|
space](https://www.linux.com/news/all-about-linux-swap-space).
|
|
|
|
## 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][CONFIGURATION.md] for more details.
