Span High Cardinality

[MatheusGelinskiPires]

Hello folks,

This part of code is generating high cardinality on APM tools:

opentelemetry-apim-agent/src/main/java/com/axway/apim/opentelemetry/HttpServer.java

Line 39 in b0f701e

Span span = tracer.spanBuilder(httpVerb + " " + requestUri).setParent(context).setSpanKind(SpanKind.SERVER).startSpan();

Could you please improve this span naming to avoid scenarios where the uri.path brings some variable ids?

Thanks,
Matheus

Hi @MatheusGelinskiPires,

What would you recommend instead of request uri (uri.path)?

e.g - httpVerb + "/"

Hello @rathnapandi,

Maybe we can use the API name (api.name) while we don't have a better solution to sanitize the request uri.

e.g - httpVerb + " " + apiName
