# 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 local or remote services.

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.

## 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 requires golang version 1.8+, the Makefile requires GNU make.

Dependencies are managed with [gdm](https://github.com/sparrc/gdm),
which is installed by the Makefile if you don't have it already.

1. [Install Go](https://golang.org/doc/install)
2. [Setup your GOPATH](https://golang.org/doc/code.html#GOPATH)
3. Run `go get -d 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
```
