Semantic kernel OTel metrics in Blazor

Question

I have a Blazor server application using Semantic Kernel and OTel. I'd like to send Semantic Kernel metrics to Application Insights. Here's my code:

AppContext.SetSwitch("Microsoft.SemanticKernel.Experimental.GenAI.EnableOTelDiagnosticsSensitive", true);
services.AddOpenTelemetry()
 .UseAzureMonitor(options =>
 {
 options.ConnectionString = appInsightsConnectionString;
 })
 .WithTracing(builder =>
 builder
 .AddSource(Telemetry.SourceName)
 .AddSource("Microsoft.SemanticKernel*")
 .SetResourceBuilder(Telemetry.ResourceBuilder)
 )
 .WithMetrics(builder => builder
 .AddMeter("Microsoft.SemanticKernel*")
 .SetResourceBuilder(Telemetry.ResourceBuilder));
services
 .AddScoped<Kernel>()
 .AddAzureOpenAIChatCompletion(deploymentName, endpoint, apiKey);

Then in my application I inject a IChatCompletionService and make a call with chatCompletionService.GetStreamingChatMessageContentsAsync(chatHistory). I see traces in Application Insights for Semantic Kernel but no metrics.

What am I missing?

Edit: If I follow this example in the documentation I do receive metrics:

using var meterProvider = Sdk.CreateMeterProviderBuilder()
 .SetResourceBuilder(resourceBuilder)
 .AddMeter("Microsoft.SemanticKernel*")
 .AddConsoleExporter()
 .Build();

• MartinDotNet: I'm not aware of any metrics that Semantic Kernel is registering. I'm also unsure if the AzureMonitor exports supports metrics. If both of those things are true then your configuration does appear to be correct.
• chris: Thanks, I updated the question to an example which does send metrics
• MartinDotNet: I'm glad you're now getting them, but I have no idea why adding a meter that sends to the console would enable sending to AzureMonitor.
• chris: I wasn't clear. I have no metrics at all, whether I try sending them to AzureMonitor or the Console, in the initial version. If I run the documentation example version I receive metrics both in AzureMonitor and the Console, when I modify their example to send it to AzureMonitor also. So in my version metrics do not work but in the documentation example they do work.
