Telegraf
|
|
||||||
=========
|
|
||||||
|
|
||||||
This will setup a [Telegraf](https://docs.influxdata.com/telegraf/) container using their official docker container to monitor the system.
|
|
||||||
|
|
||||||
Requirements
|
|
||||||
------------
|
|
||||||
|
|
||||||
You will need to have docker and docker-compose installed or declared as dependencies with their respective roles.
|
|
||||||
|
|
||||||
Role Variables
|
|
||||||
--------------
|
|
||||||
|
|
||||||
**Please look at the [defaults/main.yml](defaults/main.yml) for all available variables and their description.**
|
|
||||||
|
|
||||||
**Note: Lines that are commented out via `#` are usually still valid/used variables, but they are not defined by default, so they might enable a feature, when uncommenting/defining them!**
|
|
||||||
|
|
||||||
Dependencies
|
|
||||||
------------
|
|
||||||
|
|
||||||
- docker
|
|
||||||
- docker-compose
