Blazor: Update docs on how to get useful metrics in application insights

[Liero]

This is related mainly to Blazor Server Side, but there has been similar request for WASM as well.

I would like to get similar telemetry like in MVC, Razor Pages or WebForms.

1. page views
2. Blazor equivalents of server response time (e.g. how much took my click event handler)
3. I want my Entity Framework / ADO.NET logs correlated to an operation (e.g. button click)
4. I want to see which part of my blazor app is failing (e.g. which page fails to load, or which button click throws exception)

Those are untrivial if not impossible tasks for individual developers, but incredibly helpful for production use.

Meanwhile, could anyone provide at least partial workaround, please?

I didn't even manage to get currently logged in user for all my logs using ITelemetryInitializer in my Blazor Server Side.

It is mostly null:

public class UserTelemetryInitializer : TelemetryInitializerBase
{
    public UserTelemetryInitializer(IHttpContextAccessor httpContextAccessor) : base(httpContextAccessor)
    { }

    protected override void OnInitializeTelemetry(HttpContext platformContext, RequestTelemetry requestTelemetry, ITelemetry telemetry)
    {
        telemetry.Context.User.Id =
        telemetry.Context.User.AuthenticatedUserId =
            platformContext.User.Identity?.Name ?? string.Empty;
    }
}

@mkArtakMSFT Is there any progress fixing that issue?

There is really a partner ask here to work with the App Insights team on better client integration: microsoft/ApplicationInsights-dotnet#2143. We need to understand if this should be based on the existing App Insights JS client, or the upcoming Open Telemetry JS client support.

...And...any updates? All the bits are Microsoft, no? Can we pull things together now?
