# Telegraf - A native agent for InfluxDB [![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.
|
|
|
|
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).
|
|
|
|
We'll eagerly accept pull requests for new plugins and will manage the set of
|
|
plugins that Telegraf supports. See the
|
|
[contributing guide](CONTRIBUTING.md) for instructions on
|
|
writing new plugins.
|
|
|
|
## Installation:
|
|
|
|
### Linux deb and rpm packages:
|
|
|
|
Latest:
|
|
* 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_0.2.4.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
|
|
```
|
|
|
|
### Version 0.3.0 Beta
|
|
|
|
Version 0.3.0 will introduce many new breaking changes to Telegraf. For starters,
|
|
plugin measurements will be aggregated into fields. This means that there will no
|
|
longer be a `cpu_usage_idle` measurement, there will be a `cpu` measurement with
|
|
a `usage_idle` field.
|
|
|
|
There will also be config file changes, meaning that your 0.2.x Telegraf config
|
|
files will no longer work properly. It is recommended that you use the
|
|
`-sample-config` flag to generate a new config file to see what the changes are.
|
|
You can also read the
|
|
[0.3.0 configuration guide](https://github.com/influxdb/telegraf/blob/0.3.0/CONFIGURATION.md)
|
|
to see some of the new features and options available.
|
|
|
|
You can read more about the justifications for the aggregated measurements
|
|
[here](https://github.com/influxdb/telegraf/issues/152), and a more detailed
|
|
breakdown of the work [here](https://github.com/influxdb/telegraf/pull/437).
|
|
Once we're closer to a full release, there will be a detailed blog post
|
|
explaining all the changes.
|
|
|
|
* http://get.influxdb.org/telegraf/telegraf_0.3.0-beta2_amd64.deb
|
|
* http://get.influxdb.org/telegraf/telegraf-0.3.0_beta2-1.x86_64.rpm
|
|
* http://get.influxdb.org/telegraf/telegraf_linux_amd64_0.3.0-beta2.tar.gz
|
|

|

|
|
|
|
### 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:
|
|
|
|
* Run `telegraf -sample-config > telegraf.conf` to create an initial configuration.
|
|
* Or run `telegraf -sample-config -filter cpu:mem -outputfilter influxdb > telegraf.conf`.
|
|
to create a config file with only CPU and memory plugins defined, and InfluxDB
|
|
output defined.
|
|
* Edit the configuration to match your needs.
|
|
* Run `telegraf -config telegraf.conf -test` to output one full measurement
|
|
sample to STDOUT. NOTE: you may want to run as the telegraf user if you are using
|
|
the linux packages `sudo -u telegraf telegraf -config telegraf.conf -test`
|
|
* Run `telegraf -config telegraf.conf` to gather and send metrics to configured outputs.
|
|
* Run `telegraf -config telegraf.conf -filter system:swap`.
|
|
to run telegraf with only the system & swap plugins defined in the config.
|
|
|
|
## Telegraf Options
|
|
|
|
Telegraf has a few options you can configure under the `agent` section of the
|
|
config.
|
|
|
|
* **hostname**: The hostname is passed as a tag. By default this will be
|
|
the value returned by `hostname` on the machine running Telegraf.
|
|
You can override that value here.
|
|
* **interval**: How often to gather metrics. Uses a simple number +
|
|
unit parser, e.g. "10s" for 10 seconds or "5m" for 5 minutes.
|
|
* **debug**: Set to true to gather and send metrics to STDOUT as well as
|
|
InfluxDB.
|
|
|
|
