[Telegraf] ConfigMap telegraf Yaml => Toml error

[lpaulusLohr]

Hi,

I have an problem with ConfigMap Yaml to Toml parsing :

I want this :

    [[inputs.mqtt_consumer.json_v2.object]]
        path = "@this"
        tags = ["device","data.type","owner"] 

But the helm parsing template render it like :

    [[inputs.mqtt_consumer.json_v2.object]]
        path = "@this"
        tags = "[device data.type owner]"

My Yaml :

          object:
            path: "@this"
            tags:
              - "device"
              - "data.type"
              - "owner"

I found the problem is here in the template _helpers.tpl l.277

          [inputs.{{ $input }}.{{ $key }}.{{ $k }}]
                {{- range $foo, $bar := $v }}
            {{ $foo }} = {{ $bar | quote }}

Could you please try the latest chart with --set tplVersion=2.

Ok working as expect

Thanks for making generalization on child Inputs !
Result :

  [inputs.mqtt_consumer.json_v2]  
    measurement_name_path = "device"
    [inputs.mqtt_consumer.json_v2.object]  
      path = "@this"
      tags = [
        "device",
        "data.type",
        "owner"
      ] 

[alespour]

Should be

  [[inputs.mqtt_consumer.json_v2]]
    measurement_name_path = "device"
    [[inputs.mqtt_consumer.json_v2.object]]  
      path = "@this"
      tags = [
        "device",
        "data.type",
        "owner"
      ]   

for

        json_v2:
          - measurement_name_path: "device"
            object:
              - path: "@this"
                tags:
                  - "device"
                  - "data.type"
                  - "owner"

It's a Match 👍 : @lupaulus

json_v2:
  measurement_name_path: "device"
  object:
    path: "@this"
    tags:
      - "device"
      - "data.type"
      - "owner"

[alespour]

I see :)
OK to close the issue?

[lpaulusLohr]

@alespour I did not pay attention, but there is a problem on the title of the "section", there is only 1 hook instead of 2

[[inputs.mqtt_consumer]]    
  data_format = "json_v2"

  topics = [
    "XXXX"
  ]
  [inputs.mqtt_consumer.json_v2]  
    measurement_name_path = "device"
    [inputs.mqtt_consumer.json_v2.object]  
      path = "@this"
      tags = [
        "device",
        "data.type",
        "owner"
      ]

[alespour]

Two hooks are rendered when entries are lists. In your config there are only dictionaries, so 1 hook is correct.
In config shown in my comment json_v2 and object are lists, so there are 2 hooks rendered around the title of the section.

[lpaulusLohr]

This is my config, check if I'm wrong but I use lists :

EDIT : I'm wrong...

    - mqtt_consumer:
        topics:
          - "XXXX"
        data_format: "json_v2"
        json_v2:
          measurement_name_path: "device"
          object:
            path: "@this"
            tags:
              - "device"
              - "data.type"
              - "owner"
