Unable to use nested configuration

[joshuaspence]

I was trying to use the following Hiera configuration to create a Telegraf input:

telegraf::inputs:
  elasticsearch:
    cluster_health: true
    local: false
    servers: ['http://127.0.0.1']
    tags:
      role: 'some_role'

This resulted in the following (snippet) of configuration:

[[inputs.elasticsearch]]
  cluster_health = true
  local = false
  servers = ["http://127.0.0.1"]
  tags = {"role"=>"some_role"}

This is wrong and causes telegraf to fail:

Error parsing /etc/telegraf/telegraf.conf, toml: line 42: parse error

Rather, it should become;

[[inputs.elasticsearch]]
  cluster_health = true
  local = false
  servers = ["http://127.0.0.1"]
  [inputs.elasticsearch.tags]
    role = "some_role"

It looks like this is already supported by telegraf::input, so I think that the real issue here is that specifying inputs in $telegraf::inputs doesn't actually utilize the telegraf::input resource.

Not sure if this is still an issue.
Solving this would require a slight change in your hiera parameterization.

telegraf::inputs:
  elasticsearch:
    cluster_health: true
    local: false
    servers: ['http://127.0.0.1']
    sections:
      'elasticsearch.tags':
        role: 'some_role'
