Memory Input Plugin

The mem plugin collects system memory metrics.

For a more complete explanation of the difference between used and actual_used RAM, see Linux ate my ram.

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.
