Telegraf

tiger

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.

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:

wget -qO- https://repos.influxdata.com/influxdb.key | sudo tee /etc/apt/trusted.gpg.d/influxdb.asc >/dev/null
source /etc/os-release
echo "deb https://repos.influxdata.com/${ID} ${VERSION_CODENAME} stable" | sudo tee /etc/apt/sources.list.d/influxdb.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:

cat <<EOF | sudo tee /etc/yum.repos.d/influxdb.repo
[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
EOF
sudo yum install telegraf

Build From Source

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