Remove Azure SDK generated logs

Question

I have a .net Core 3.1 web app that connects to different Storage Accounts using Azure MSI. The services are initialized using the Azure.Core.Extensions nuget package.

        var options = new BlobClientOptions
        {
            Diagnostics =
            {
                IsLoggingEnabled = false,
                IsTelemetryEnabled = false,
                IsDistributedTracingEnabled = false,
                IsLoggingContentEnabled = false
            },
            Retry =
            {
                MaxRetries = 3,
                Mode = RetryMode.Exponential,
                NetworkTimeout = TimeSpan.FromSeconds(120),
                Delay = TimeSpan.FromSeconds(0.7)
            }
        };
        builder.AddBlobServiceClient(StorageAccountConfigurator.GetStorageAccountUri(accountName))
                        .WithName(accountName)
                        .ConfigureOptions(options);

Everything works ok, but in Application Insights I get too many traces with this message:

ManagedIdentityCredential.GetToken succeeded. Scopes: [ https://storage.azure.com/.default ] 

These are traces with Severity level:Information, Category:Azure.Identity.

Azure.Identity does not appear as a independent category in the documentation:https://learn.microsoft.com/en-us/aspnet/core/fundamentals/logging/?view=aspnetcore-6.0

I have tried to create a ApplicationInsightsFilter (implements ITelemetryProcessor) to catch such traces and exclude them from logs, but somehow they overpass it (while debugging I was not able to catch such traces).

Is there an option to stop them from appearing in the logs?

You can specify the log levels for Azure.Identity Package also in your appsettings.json file as specified in the Logging Configuration and Azure SDKs Logging Microsoft docs.

For example:

{
  "Logging": {
    "LogLevel": {
      "Default": "Information",
      "Azure.Identity": "Information",
      "Azure.Core": "Debug"
    }
  }
}
