Telegraf Circle CI Docker pulls

Telegraf is an agent written in Go 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 from well known services (like Hadoop, Postgres, or Redis) and third party APIs (like Mailchimp, AWS CloudWatch, or Google Analytics).

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

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

For more information on Processor and Aggregator plugins please read this.

New plugins are designed to be easy to contribute, we'll eagerly accept pull requests and will manage the set of plugins that Telegraf supports.

Contributing

There are many ways to contribute:

Installation:

You can download the binaries directly from the downloads page or from the releases section.

Ansible Role:

Ansible role: https://github.com/rossmcdonald/telegraf

From Source:

Telegraf manages dependencies via gdm, which gets installed via the Makefile if you don't have it already. You also must build with golang version 1.8+.

  1. Install Go
  2. Setup your GOPATH
  3. Run go get github.com/influxdata/telegraf
  4. Run cd $GOPATH/src/github.com/influxdata/telegraf
  5. Run make

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 --input-filter cpu --output-filter influxdb config

Run a single telegraf collection, outputing 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

Configuration

See the configuration guide for a rundown of the more advanced configuration options.

Input Plugins

Telegraf can also collect metrics via the following service plugins:

Telegraf is able to parse the following input data formats into metrics, these formats may be used with input plugins supporting the data_format option:

Processor Plugins

Aggregator Plugins

Output Plugins
