# Telegraf [![Circle CI](https://circleci.com/gh/influxdata/telegraf.svg?style=svg)](https://circleci.com/gh/influxdata/telegraf) [![Docker pulls](https://img.shields.io/docker/pulls/library/telegraf.svg)](https://hub.docker.com/_/telegraf/)
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](#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).
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:
- Fix and [report bugs](https://github.com/influxdata/telegraf/issues/new)
- [Improve documentation](https://github.com/influxdata/telegraf/issues?q=is%3Aopen+label%3Adocumentation)
- [Review code and feature proposals](https://github.com/influxdata/telegraf/pulls)
- Answer questions on github and on the [Community Site](https://community.influxdata.com/)
- [Contribute plugins](CONTRIBUTING.md)
## Installation:
You can download the binaries directly from the [downloads](https://www.influxdata.com/downloads) page
or from the [releases](https://github.com/influxdata/telegraf/releases) section.
### Ansible Role:
Ansible role: https://github.com/rossmcdonald/telegraf
### From Source:
Telegraf manages dependencies via [gdm](https://github.com/sparrc/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](https://golang.org/doc/install)
2. [Setup your GOPATH](https://golang.org/doc/code.html#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
```
