Circle CI Docker pulls Slack Status

Telegraf is an agent for collecting, processing, aggregating, and writing metrics. Based on a plugin system to enable developers in the community to easily add support for additional metric collection. There are four distinct types of plugins:

  1. Input Plugins collect metrics from the system, services, or 3rd party APIs
  2. Processor Plugins transform, decorate, and/or filter metrics
  3. Aggregator Plugins create aggregate metrics (e.g. mean, min, max, quantiles, etc.)
  4. Output Plugins write metrics to various destinations

New plugins are designed to be easy to contribute, pull requests are welcomed, and we work to incorporate as many pull requests as possible. Consider looking at the list of external plugins as well.

Telegraf shares the same minimum requirements as Go:

Binary Downloads

Binary downloads are available from the InfluxData downloads page or from each GitHub Releases page.

Package Repository

InfluxData also provides a package repo that contains both DEB and RPM downloads.

For deb-based platforms run the following to add the repo key and setup a new sources.list entry:

curl -s https://repos.influxdata.com/influxdb.key | gpg --dearmor > /etc/apt/trusted.gpg.d/influxdb.gpg
export DISTRIB_ID=$(lsb_release -si); export DISTRIB_CODENAME=$(lsb_release -sc)
echo "deb [signed-by=/etc/apt/trusted.gpg.d/influxdb.gpg] https://repos.influxdata.com/${DISTRIB_ID,,} ${DISTRIB_CODENAME} stable" > /etc/apt/sources.list.d/influxdb.list

For RPM-based platforms use the following repo file in /etc/yum.repos.d/:

[influxdb]
name = InfluxDB Repository - RHEL $releasever
baseurl = https://repos.influxdata.com/rhel/$releasever/$basearch/stable
enabled = 1
gpgcheck = 1
gpgkey = https://repos.influxdata.com/influxdb.key

Build From Source

Telegraf requires Go version 1.17 or newer, the Makefile requires GNU make.

  1. Install Go >=1.17 (1.17.2 recommended)

Nightly Builds

Nightly builds are available, generated from the master branch.

3rd Party Builds

Builds for other platforms or package formats are provided by members of theTelegraf community. These packages are not built, tested, or supported by the Telegraf project or InfluxData. Please get in touch with the package author if support is needed:

Getting Started

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 --section-filter agent:inputs:outputs --input-filter cpu --output-filter influxdb config

Run a single telegraf collection, outputting 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
