Rebus.OpenTelemetry

Makes Rebus emit Diagnostic traces, which OpenTelemetry can be used to generate tracing.

Usage

Add the packages:

Rebus.Diagnostics Rebus.OpenTelemetry

When configuring Rebus call EnableDiagnosticSources like this:

using var publisherActivator = new BuiltinHandlerActivator(); var bus = Configure.With(publisherActivator) .Transport(t => t.UseInMemoryTransport(new InMemNetwork(), "Messages")) .Options(o => o.EnableDiagnosticSources()) // This is the important line .Start();

Then add Rebus tracing to your OpenTelemetry calls, by doing AddRebusInstrumentation:

var tracerProvider = Sdk.CreateTracerProviderBuilder() .AddRebusInstrumentation() .Build()

And then everything should just work. 🙂
