Integer values reported as 0

[StefanVanDyck]

Thank you so much for writing this tool.
It's been super helpful.

Unfortunately we ran into an issue where all our status code, etc. showed up as 0 on our dashboards.
The issues seems to be the conversion from the opcua datatype to a float.

I managed fix my local copy by adding this simple switch statement to the GetOpcuaValueFromIndex method.

switch r.Value.Type() {
	case ua.TypeIDInt16:
		fallthrough
	case ua.TypeIDInt32:
		fallthrough
	case ua.TypeIDInt64:
		fallthrough
	case ua.TypeIDUint16:
		fallthrough
	case ua.TypeIDUint32:
		fallthrough
	case ua.TypeIDUint64:
		return float64(r.Value.Int()), nil
	}
	return r.Value.Float(), nil

I'll create a quick PR for you to look at.

I am not a talented go developer by any means.
But the fix seems straightforward enough.

Thanks!

Hello @StefanVanDyck 👋

Thank you for your contribution 🙏 and sorry for the delay.

We have already changed the architecture of this software. I will do my best to update the repository ASAP. Meanwhile, here is the function we use to extract the values. You can use it until the repository is updated.

func (m Message) Float() (float64, error) {
   v, ok := m.Value.(*ua.Variant)
   if !ok {
   	return 0, errors.New("message value can't be parsed as ua.Variant")
   }
   valI := v.Value()
   var val float64

   switch v.Type() {
   case ua.TypeIDSByte:
   	val = float64(valI.(int8))
   case ua.TypeIDByte:
   	val = float64(valI.(uint8))
   case ua.TypeIDInt16:
   	val = float64(valI.(int16))
   case ua.TypeIDUint16:
   	val = float64(valI.(uint16))
   case ua.TypeIDInt32:
   	val = float64(valI.(int32))
   case ua.TypeIDUint32:
   	val = float64(valI.(uint32))
   case ua.TypeIDInt64:
   	val = float64(valI.(int64))
   case ua.TypeIDUint64:
   	val = float64(valI.(uint64))
   case ua.TypeIDFloat:
   	val = float64(valI.(float32))
   case ua.TypeIDDouble:
   	val = valI.(float64) //nolint:errcheck
   case ua.TypeIDBoolean:
   	if valI.(bool) {
   		val = 1
   	}
   default:
   	return 0, errors.New("not a numeric type")
   }
   return val, nil
}
