    FieldList (each field with key, value) 
    Time
    Type (Counter, Gauge, Summary, Histogram, or Untyped)
}

to OpenTelemetry Int64DataPoints, DoubleDataPoints metrics datapoints

Metrics {
    ResourceMetrics: list of {
      Resource: {
        Attributes: map of {key: value}
      }
      InstrumentationScopeMetrics: list of {

        Metrics: list of {
          Name
          Description
          Unit
          DataType (None, Gauge, Sum, Histogram, Summary)
          depending on DataType, e.g. Gauge: {
            DataPoints: list of {
              Attributes: map of {key: value}
              Timestamp
              Type (None, Int, Double)
              Val
            }
          }
