Telegraf

Contribute Slack Status Circle CI GoDoc Docker pulls Go Report Card

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.

Minimum Requirements

Telegraf shares the same minimum requirements as Go:

  • Linux kernel version 2.6.23 or later
  • Windows 7 or later
  • FreeBSD 11.2 or later
  • MacOS 10.11 El Capitan or later

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 (e.g. Ubuntu and Debian) run the following to add the repo key and setup a new sources.list entry:

# influxdb.key GPG Fingerprint: 05CE15085FC09D18E99EFB22684A14CF2582E0C5
wget -q https://repos.influxdata.com/influxdb.key
echo '23a1c8836f0afc5ed24e0486339d7cc8f6790b83886c4c96995b88a061c5bb5d influxdb.key' | sha256sum -c && cat influxdb.key | gpg --dearmor | sudo tee /etc/apt/trusted.gpg.d/influxdb.gpg > /dev/null
echo 'deb [signed-by=/etc/apt/trusted.gpg.d/influxdb.gpg] https://repos.influxdata.com/debian stable main' | sudo tee /etc/apt/sources.list.d/influxdata.list
sudo apt-get update && sudo apt-get install telegraf

For RPM-based platforms (e.g. RHEL, CentOS) use the following to create a repo file and install telegraf:

# influxdb.key GPG Fingerprint: 05CE15085FC09D18E99EFB22684A14CF2582E0C5
cat <<EOF | sudo tee /etc/yum.repos.d/influxdata.repo
[influxdata]
name = InfluxData Repository - Stable
baseurl = https://repos.influxdata.com/stable/\$basearch/main
enabled = 1
gpgcheck = 1
gpgkey = https://repos.influxdata.com/influxdb.key
EOF
sudo yum install telegraf

Build From Source

Telegraf requires Go version 1.18 or newer, the Makefile requires GNU make.

On Windows, the makefile requires the use of a bash terminal to support all makefile targets. An easy option to get bash for windows is using the version that comes with git for windows.

  1. Install Go >=1.18 (1.18.0 recommended)

  2. Clone the Telegraf repository:

    git clone https://github.com/influxdata/telegraf.git
  3. Run make build from the source directory

    cd telegraf
    make build

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

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
