Swap Input Plugin

The swap plugin collects system swap metrics.

For more information on what swap memory is, read All about Linux swap space.

Global configuration options

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 for more details.
