Misleading variable 'operation'

[arpitjindal97]

My understanding is it defines the task that an HTTP handler tends to do in a particular API call.

Example:

otelhttp.NewHandler(SearchQuery, "/search")
otelhttp.NewHandler(GetA, "/getA")
otelhttp.NewHandler(PostA, "/PostA")
otelhttp.NewHandler(Test, "Operation")

But looking at the implementation otel has done. It means server_name. In the final metrics, it's displayed as http_server_name

Is this the expected behavior? or maybe I'm missing something. Let me know how can endpoint-specific metrics be collected.
