Akka.OpenTelemetry

This is a library that provides OpenTelemetry instrumentation for Akka.NET. Status is work in progress.

Tracing currently works for:

• Local Actors
• Remote Actors
• ActorSelections
• Async-Await, tracing does propagate across async boundaries

And where it doesn't work:

• Cluster Actors
• Remote Deployed Actors

Akka.OpenTelemetry has been tested with Asynkron TraceView

Asynkron TraceView

There are currently no configuration support, all actors in /user/-space are traced.

Pull-requests are welcome.

Getting started

Installation

Install the NuGet package Akka.OpenTelemetry into your Akka.NET application.

Configuration

var tracerProvider = Sdk.CreateTracerProviderBuilder()
    .SetResourceBuilder(ResourceBuilder.CreateDefault()
        .AddService("Akka.OpenTelemetry.Demo")
    )
    .AddAkkaInstrumentation()
    .AddOtlpExporter(options =>
    {
        options.Endpoint = new Uri("http://localhost:4317");
        options.ExportProcessorType = ExportProcessorType.Batch;
    })
    .Build();
    

//augment config with OpenTelemetry settings
var bootstrap = BootstrapSetup.Create().WithOpenTelemetry();
var system = ActorSystem.Create("my-system", bootstrap);
var props = Props.Create<MyActor>();
var reff = system.ActorOf(props);
