telegraf

[frondot]

Hello,

It is possible to install telegraf on TrueNAS Scale RC2 ?
I thinks it's like a standard Debian install from InfluxDB website ?

Best regards,
Franck

Truenas is an appliance, not a general-purpose Debian varient. While it may be possible using apt to install something like Telegraf it's not supported or recommended and may or may not work/break other things. Also the changes won't survive updates so you'd have to re-do them.

You can do what I do and run Telegraf in a docker container and mount the local system to it in read-only mode. This works the same as the local install.

Here's an example from my docker-compose.

Code:

  telegraf:
    image: telegraf:latest
    networks:
      t2_proxy:
    pid: "host"
    depends_on:
      - influxdb2
    container_name: telegraf
    restart: on-failure:10
    mem_limit: $MEM_LOW
    cpus: $CPU_LOW
    volumes:
      - $APPDIR/telegraf/telegraf.conf:/etc/telegraf/telegraf.conf:ro
      #- /var/run/docker.sock:/var/run/docker.sock:ro
      - /sys:/host/sys:ro
      - /proc:/host/proc:ro
      - /etc:/host/etc:ro
      - /run:/host/run:ro
      - /var:/host/var:ro
    environment:
      DOCKER_HOST: "tcp://socket-proxy:2375"
      HOST_PROC: /host/proc
      HOST_SYS: /host/sys
      HOST_ETC: /host/etc
      HOST_RUN: /host/run
      HOST_VAR: /host/var
      HOST_MOUNT_PREFIX: /host
    labels:   
      - "com.centurylinklabs.watchtower.enable=true"

Note that it is custom to my system and variables so don't blindly copy and paste, this is just to give some pointers on how to do it. You don't have to use Compose, you can create your own docker container in the GUI. Also I'd check to see if the Truecharts folks have a Telegraf "app" available.

Thanks Ixian, it’s perfect !

Also I'd check to see if the Truecharts folks have a Telegraf "app" available.

At the moment we decided to limit ourselves to Prometheus for the first release of SCALE :)
But the rest of your explaination is solid none-the-less!

I think it is possible. I do not sure about it
