Ability to disable ConnectionId and RequestId + RequestPath scopes

We use scopes to identify log entries as coming from a certain tenant, this is a critical part of our diagnostic ability.

Scopes have various performance downsides but due to the value they provide we really wouldn’t want to disable them completely. We also add all scopes to our json logger going to cloud logging and the smaller these messages can be the better, there is a direct financial cost attached to ingestion of larger than need be messages over time.

However, and this is the issue, in the framework there exist a few scope pushes that have limited or no value for us and can’t be turned off without also turning off important log messages.

ConnectionId is not relevant to us, but we can’t turn it off because all of it is enabled under category Microsoft.AspNetCore.Server.Kestrel which also contains important log messages like reaching connection limits.

RequestId is really not relevant anymore (at least to us) with SpanId and TraceId being integrated by default but we can’t turn it off RequestPath is occasionaly useful but we could just as well emit it ourselves.

Our minimal scopes would ideally look like:

• Activity scope (implemented in https://github.com/dotnet/runtime/pull/37092)
• Our own scopes like tenantid, userid.

Would it be possible to provide knob(s) to disable these kestrel scopes somewhere, like in KestrelServerOptions? (not sure where RequestId + RequestPath comes from)

You can exclude scopes by configuring ActivityTrackingOptions when initialising the logging service.

builder.Services.AddLogging(options =>
{
    options.Configure(c => c.ActivityTrackingOptions = ActivityTrackingOptions.None);
});

Yes, agree with this. I just tried to add OpenTelemetry context to JSON console logging in an ASP.NET Core 6 project.

Using the “IncludeScopes” formatter option I get the below scopes on a log , when all I really want is the TraceId/SpanId for correlation purposes.

"Scopes": [
    {
      "Message": "SpanId:7d01d402b9b9fda5, TraceId:ebd21c67aaf93cc221a6ea2ecc416a24",
      "SpanId": "7d01d402b9b9fda5",
      "TraceId": "ebd21c67aaf93cc221a6ea2ecc416a24"
    },
    {
      "Message": "ConnectionId:0HMP7SSS89CFI",
      "ConnectionId": "0HMP7SSS89CFI"
    },
    {
      "Message": "RequestPath:/x/y RequestId:0HMP7SSS89CFI:00000002",
      "RequestId": "0HMP7SSS89CFI:00000002",
      "RequestPath": "/x/y"
    },
    {
      "Message": "XXX.PostAsync (YYY)",
      "ActionId": "0e04439b-492e-4a1c-aea8-7131c3f64482",
      "ActionName": "XXX.PostAsync (YYY)"
    }
