+Telegraf is plugin-driven and has the concept of 4 distinct plugin types:
 
 1. [Input Plugins](#input-plugins) collect metrics from the system, services, or 3rd party APIs
 2. [Processor Plugins](#processor-plugins) transform, decorate, and/or filter metrics
 3. [Aggregator Plugins](#aggregator-plugins) create aggregate metrics (e.g. mean, min, max, quantiles, etc.)
 4. [Output Plugins](#output-plugins) write metrics to various destinations
 
-For more information on Processor and Aggregator plugins please [read this](./docs/AGGREGATORS_AND_PROCESSORS.md).
