|
|
|
|
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](/docs/INPUTS.md) collect metrics from the system, services, or 3rd party APIs
|
|
2. [Processor Plugins](/docs/PROCESSORS.md) transform, decorate, and/or filter metrics
|
|
3. [Aggregator Plugins](/docs/AGGREGATORS.md) create aggregate metrics (e.g. mean, min, max, quantiles, etc.)
|
|
4. [Output Plugins](/docs/OUTPUTS.md) 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](EXTERNAL_PLUGINS.md) as well.
|
|
|
|

|
### Binary Downloads
|
|
|
|
Binary downloads are available from the [InfluxData downloads](https://www.influxdata.com/downloads)
|
|
page or from each [GitHub Releases](https://github.com/influxdata/telegraf/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:
|
|
|
|
```shell
|
|
# influxdata-archive_compat.key GPG fingerprint:
|
|
# 9D53 9D90 D332 8DC7 D6C8 D3B9 D8FF 8E1F 7DF8 B07E
|
|
wget -q https://repos.influxdata.com/influxdata-archive_compat.key
|
|
echo '393e8779c89ac8d958f81f942f9ad7fb82a25e133faddaf92e15b16e6ac9ce4c influxdata-archive_compat.key' | sha256sum -c && cat influxdata-archive_compat.key | gpg --dearmor | sudo tee /etc/apt/trusted.gpg.d/influxdata-archive_compat.gpg > /dev/null
|
|
echo 'deb [signed-by=/etc/apt/trusted.gpg.d/influxdata-archive_compat.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:
|
|
|
|
```shell
|
|
# influxdata-archive_compat.key GPG fingerprint:
|
|
# 9D53 9D90 D332 8DC7 D6C8 D3B9 D8FF 8E1F 7DF8 B07E
|
|
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/influxdata-archive_compat.key
|
|
EOF
|
|
sudo yum install telegraf
|
|
```
|
|
|
|
### Build From Source
|
|
|
|
Telegraf requires Go version 1.21 or newer and 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](https://gitforwindows.org/).
|
|
|
|
1. [Install Go](https://golang.org/doc/install)
|
|
2. Clone the Telegraf repository:
|
|
|
|
```shell
|
|
git clone https://github.com/influxdata/telegraf.git
|
|
```
|
|
|
|
3. Run `make build` from the source directory
|
|
|
|
```shell
|
|
cd telegraf
|
|
make build
|
|
```
|
|
|
|
### Nightly Builds
|
|
|
|
[Nightly](/docs/NIGHTLIES.md) builds are available, generated from the master branch.
|
|
|
|
### 3rd Party Builds
