Dedup Processor Plugin

This plugin filters metrics whose field values are exact repetitions of the previous values. This plugin will store its state between runs if the statefile option in the agent config section is set.

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.
