# Telegraf [![Circle CI](https://circleci.com/gh/influxdata/telegraf.svg?style=svg)](https://circleci.com/gh/influxdata/telegraf)
2015-05-20 05:26:13 +00:00
Telegraf is an agent written in Go for collecting metrics from the system it's
2016-01-07 22:21:10 +00:00
running on, or from other services, and writing them into InfluxDB or other
[outputs](https://github.com/influxdata/telegraf#supported-output-plugins).
2015-06-19 16:34:27 +00:00
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).

2016-01-07 22:21:10 +00:00
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.

### OSX via Homebrew:
```
brew update
brew install telegraf
```
### From Source:
2015-12-08 23:18:23 +00:00
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:
2016-01-07 22:21:10 +00:00
```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
```
