Telegraf
Telegraf is an agent for collecting, processing, aggregating, and writing metrics.
Design goal:
- 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:
- Input Plugins collect metrics from the system, services, or 3rd party APIs
- Processor Plugins transform, decorate, and/or filter metrics
- Aggregator Plugins create aggregate metrics (e.g. mean, min, max, quantiles, etc.)
- Output Plugins write metrics to various destinations
New plugins are designed to be easy to contribute, pull requests are welcomed and we work to incorporate as many pull requests as possible. If none of the internal plugins fit your needs, you could have a look at the list of external plugins.

How to use it:
See usage with:
telegraf --help
Generate a telegraf config file:
telegraf config > telegraf.conf
Generate config with only cpu input & influxdb output plugins defined:
telegraf --section-filter agent:inputs:outputs --input-filter cpu --output-filter influxdb config
Run a single telegraf collection, outputting metrics to stdout:
telegraf --config telegraf.conf --test
Run telegraf with all plugins defined in config file:
telegraf --config telegraf.conf
Run telegraf, enabling the cpu & memory input, and influxdb output plugins:
telegraf --config telegraf.conf --input-filter cpu:mem --output-filter influxdb
