# Telegraf [](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 0.10.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.
|
|
|
|
For more details on the differences between Telegraf 0.2.x and 0.10.x, see
|
|
the [release blog post](https://influxdata.com/blog/announcing-telegraf-0-10-0/).

|
|
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
|
|
```
