Telegraf

Agente recolector de métricas

Instalación

Añadimos el repositorio de InfluxData: 

wget -qO- https://repos.influxdata.com/influxdb.key | sudo apt-key add -
source /etc/os-release
test $VERSION_ID = "7" && echo "deb https://repos.influxdata.com/debian wheezy stable" | sudo tee /etc/apt/sources.list.d/influxdb.list
test $VERSION_ID = "8" && echo "deb https://repos.influxdata.com/debian jessie stable" | sudo tee /etc/apt/sources.list.d/influxdb.list
test $VERSION_ID = "9" && echo "deb https://repos.influxdata.com/debian stretch stable" | sudo tee /etc/apt/sources.list.d/influxdb.list
test $VERSION_ID = "10" && echo "deb https://repos.influxdata.com/debian buster stable" | sudo tee /etc/apt/sources.list.d/influxdb.list

Actualizamos repositorios e instalamos: 

sudo apt-get update && sudo apt-get install telegraf

Docker

Imagen oficial.

Si queremos personalizar la configuración, lanzamos un contenedor de la siguiente manera: 

docker run --rm telegraf telegraf config > telegraf.conf

Esto creará un fichero telegraf.conf con la configuración por defecto. Lo adaptamos a nuestro gusto y luego lo pasamos al contenedor:

docker-compose.yml: 

version: '3'

services:
  app:
    container_name: telegraf
    image: telegraf
    restart: "no"
    volumes:
      - ./conf/telegraf.conf:/etc/telegraf/telegraf.conf:ro
