# Telegraf [![Circle CI](https://circleci.com/gh/influxdata/telegraf.svg?style=svg)](https://circleci.com/gh/influxdata/telegraf)

Telegraf is an agent written in Go for collecting metrics from the system it's
running on, or from other services, and writing them into InfluxDB or other
[outputs](https://github.com/influxdata/telegraf#supported-output-plugins).

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).

New input and output plugins are designed to be easy to contribute,
we'll eagerly accept pull
requests and will manage the set of plugins that Telegraf supports.
See the [contributing guide](CONTRIBUTING.md) for instructions on writing
new plugins.

## Installation:

NOTE: Telegraf 0.3.x is **not** backwards-compatible with previous versions of
telegraf, both in the database layout and the configuration file. 0.2.x will
continue to be supported, see below for download links.

TODO: link to blog post about 0.3.x changes.

### Linux deb and rpm packages:

Latest:
* http://get.influxdb.org/telegraf/telegraf_0.3.0_amd64.deb
* http://get.influxdb.org/telegraf/telegraf-0.3.0-1.x86_64.rpm

0.2.x:
* http://get.influxdb.org/telegraf/telegraf_0.2.4_amd64.deb
* http://get.influxdb.org/telegraf/telegraf-0.2.4-1.x86_64.rpm

##### Package instructions:

* Telegraf binary is installed in `/opt/telegraf/telegraf`
* Telegraf daemon configuration file is in `/etc/opt/telegraf/telegraf.conf`
* On sysv systems, the telegraf daemon can be controlled via
`service telegraf [action]`
* On systemd systems (such as Ubuntu 15+), the telegraf daemon can be
controlled via `systemctl [action] telegraf`

### Linux binaries:

Latest:
* http://get.influxdb.org/telegraf/telegraf_linux_amd64_0.3.0.tar.gz
* http://get.influxdb.org/telegraf/telegraf_linux_386_0.3.0.tar.gz
* http://get.influxdb.org/telegraf/telegraf_linux_arm_0.3.0.tar.gz

0.2.x:
* http://get.influxdb.org/telegraf/telegraf_linux_amd64_0.2.4.tar.gz
* http://get.influxdb.org/telegraf/telegraf_linux_386_0.2.4.tar.gz
* http://get.influxdb.org/telegraf/telegraf_linux_arm_0.2.4.tar.gz

##### Binary instructions:

These are standalone binaries that can be unpacked and executed on any linux
system. They can be unpacked and renamed in a location such as
`/usr/local/bin` for convenience. A config file will need to be generated,
see "How to use it" below.

### OSX via Homebrew:

```
brew update
brew install 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 1.4+.

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/influxdb/telegraf`
4. Run `cd $GOPATH/src/github.com/influxdb/telegraf`
5. Run `make`

### How to use it:

```console
$ telegraf -help
Telegraf, The plugin-driven server agent for reporting metrics into InfluxDB

Usage:

  telegraf <flags>

The flags are:

  -config <file>     configuration file to load
  -test              gather metrics once, print them to stdout, and exit
  -sample-config     print out full sample configuration to stdout
  -config-directory  directory containing additional *.conf files
  -input-filter      filter the input plugins to enable, separator is :
  -output-filter     filter the output plugins to enable, separator is :
  -usage             print usage for a plugin, ie, 'telegraf -usage mysql'
  -version           print the version to stdout

Examples:

  # generate a telegraf config file:
  telegraf -sample-config > telegraf.conf

  # generate config with only cpu input & influxdb output plugins defined
  telegraf -sample-config -input-filter cpu -output-filter influxdb

  # 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](CONFIGURATION.md) for a rundown of the more advanced
configuration options.
