GiG.Core.DistributedTracing.Orleans

This Library provides an API to register Distributed Tracing for an Orleans Client.

Activity

Silo

The below code needs to be added to the Program.cs, to add the Activity Incoming Grain call filter. Make use of AddActivityAccessor() when creating an IHostBuilder and this will register the Activity context accessor.

Note: The AddActivityAccessor extension can be found in the nuget package GiG.Core.DistributedTracing.Activity

Note: The UseOrleans extension can be found in the nuget package Microsoft.Orleans.Server

static class Program
{
    public static void Main()
    {
        CreateHostBuilder().Build().Run();
    }

    private static IHostBuilder CreateHostBuilder(string[] args) =>
        Host.CreateDefaultBuilder(args)
            .ConfigureServices((ctx, services) => 
            {
                services.AddActivityAccessor();
            })
            .ConfigureServices(Startup.ConfigureServices)
            .UseOrleans((hostBuilder, siloBuilder) =>
                siloBuilder.ConfigureCluster(hostBuilder.Configuration)
                    .ConfigureEndpoints(hostBuilder.Configuration)
                    .AddActivityIncomingFilter());
}

Client

Add the below to your Startup class and this will add the Activity Outgoing Grain call filter.

Note: The AddActivityAccessor extension can be found in the nuget package GiG.Core.DistributedTracing.Activity

Note: The AddDefaultClusterClient extension can be found in the nuget package GiG.Core.Orleans.Client

public void ConfigureServices(IServiceCollection services)
{
    // Activty Context Accessor
    services.AddActivityAccessor();

    // Orleans Client
    services.AddDefaultClusterClient((builder, sp) =>
    {
        builder.AddActivityOutgoingFilter(sp);
        builder.ConfigureCluster(_configuration);
        builder.AddAssemblies(typeof(IWalletGrain));
    });
}
