Telegraf is an agent for collecting, processing, aggregating, and writing metrics.

Design goals are to have a minimal memory footprint with a plugin system so that developers in the community can easily add support for collecting metrics.

Telegraf is plugin-driven and has the concept of 4 distinct plugin types:

1. Input Plugins collect metrics from the system, services, or 3rd party API

2. Processor Plugins transform, decorate, and/or filter metrics

3. Aggregator Plugins create aggregate metrics (e.g. mean, min, max, quantiles, etc.)

4. Output Plugins write metrics to various destinations
