Semantic convention type mismatch for http.status_code

[danelson]

What are you trying to achieve?

I am trying to understand if it is intentional that the type as described by the semantic conventions for http.status_code is different for Metrics and Traces.

• Metrics defines it as a string (although ambiguous because the example value 200 does not use quotes ("))
• Traces defines it as int

What did you expect to see?

I expect these to be the same type for each of Logs/Metrics/Traces and that all SDKs follow the same convention. For example, in the dotnet SDK, Metrics use string and Traces use int.

Additional context.

• My assumption is that this could be an artifact of when Metrics only support attributes of type string.
• Metrics are handled differently by different SDKs (might be related to the ambiguity mentioned above)
  • Python uses an int
  • Dotnet uses a string
• I am currently working around this by using the attributes proccessor with the convert function.
