Phobos.Tracing 2.11.0

# Phobos  [Phobos](https://phobos.petabridge.com/)™ is an observability plugin for [Akka.NET](https://getakka.net/) that provides [OpenTelemetry](https://opentelemetry.io/)-based tracing, metrics, and log aggregation. [Phobos is available for purchase on Sdkbin](https://sdkbin.com/publisher/petabridge/product/phobos) ## Installation Phobos plugs directly into your Akka.NET `ActorSystem` and immediately starts providing automatic tracing, metrics, and log correlation without you having to write any instrumentation code yourself. ### 1 - Add the `Phobos.Hosting` NuGet Package ```shell dotnet add package Phobos.Hosting ``` ### 2 - Configure OpenTelemetry to Use Phobos Metrics and Tracing ```csharp services // IServiceCollection .AddOpenTelemetry() .ConfigureResource(builder => { builder .AddEnvironmentVariableDetector() .AddTelemetrySdk() .AddServiceVersionDetector(); }) .UseOtlpExporter(OtlpExportProtocol.Grpc, new Uri(otlpEndpoint)) .WithMetrics(c => { c.AddRuntimeInstrumentation() .AddAspNetCoreInstrumentation() .AddHttpClientInstrumentation() .AddPhobosInstrumentation(); // Phobos metrics }) .WithTracing(c => { c.AddHttpClientInstrumentation() .AddAspNetCoreInstrumentation() .AddEntityFrameworkCoreInstrumentation() .AddSqlClientInstrumentation() .AddPhobosInstrumentation(); // Phobos traces }); ``` ### 3 - Add Phobos to Your `ActorSystem` ```csharp public static IServiceCollection AddUserServiceAkka(this IServiceCollection services, Action<AkkaConfigurationBuilder, IServiceProvider> additionalConfig) { return services.AddAkka(ActorSystemName, (builder, sp) => { builder.AddUserServiceActors() WithPhobos(AkkaRunMode.Local, configOptions => {}); additionalConfig.Invoke(builder, sp); }); } ``` And you're done! Akka.NET traces / metrics / logs will now be automatically exported along with your ASP.NET Core, Entity Framework, SqlClient, HttpClient, and other .NET OpenTelemetry data!
