AspNetCore.SignalR.OpenTelemetry v1.6.0

Enhancements:

• #70 Add Filter option.
• #71 #73 #75 Add UseParentTraceContext option.
• #72 Add signalr.connection.id attribute to traces.

builder.Services.AddSignalR()
    .AddHubInstrumentation(options =>
    {
        // same as LINQ's Where method
        options.Filter = context =>
        {
            return context.HubMethodName != "MethodNameOfNotCaptureTraces";
        };
    });

Breaking changes:

SignalR method invocation traces are now the root trace by default; if you prefer the existing behavior up to v1.5, use the UseParentTraceContext option.

builder.Services.AddSignalR()
    .AddHubInstrumentation(options =>
    {
        // By default, UseParentTraceContext is false.
        // If set to true, the behavior is equivalent to v1.5 and earlier.
        options.UseParentTraceContext = true;
    });
