GoLang struct to exporter yaml configuration

[mrceyhun]

Hi folks,

Is there any way to convert directly GoLang struct to exporter yaml configuration? We've a go service that expose data as JSON but we need to convert these JSONs to Prometheus format to store metrics in Prometheus/VM. Go struct is nested and complex, so I don't want to spent time on manually writing json_exporter yaml configuration for it if there is an easy way.

For example: this struct (not that simple though)

type DBInfo struct {
	FullSize  float64
	IndexSize float64
}

to this yaml

....
    metrics:
    - name: full_size
      path: '{.FullSize}'
    - name: index_size
      path: '{.IndexSize}'

Thanks in advance.
