Library name and version

Azure.Monitor.OpenTelemetry.AspNetCore 1.2.0

Query/Question

Hi,

Prologue
We use built-in .NET Core authentication/authorization with multiple schemes for different OpenID providers. Each time I request my API, first call makes requests to all OpenID providers’ “.well-known” endpoints. So far it’s ok. But it creates request and dependency traces for each operation in Application Insights. That traces are totally irrelevant for us and we would like to filter them. I followed your guidelines and did something like this:

builder.Services.AddOpenTelemetry().UseAzureMonitor();
builder.Services.Configure<HttpClientTraceInstrumentationOptions>(options =>
{
    options.FilterHttpRequestMessage = req =>
        !req.RequestUri.ToString().Contains(".well-known");
});

Problems

1. When I do that it still creates “request” telemetry types, even though the condition above is correct. (picture below)
2. UseAzureMonitor has it’s own configured Http instrumentation, which is overridden when I do that.

Questions

1. How I can fully filter them out? Give me some suggestions please.
2. Overriding Http instrumentation seems to me like a violation in the opposite to UseAzureMonitor, as it has its own purpose. I would see that those filtering as additive, instead of replacement. Am I doing something wrong or for know it’s the only way to do that?
3. I created ActivityFilteringProcessor with setting up IsAllDataRequested = false but it does not totally filter out the traces.
