Telegraf
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:
- Input Plugins collect metrics from the system, services, or 3rd party APIs
- Processor Plugins transform, decorate, and/or filter metrics
- Aggregator Plugins create aggregate metrics (e.g. mean, min, max, quantiles, etc.)
- 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

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
