NBB.Messaging.OpenTelemetry

NBB.Messaging.OpenTelemetry

This package provides open telemetry support in the messaging publishers and subscribers.

NuGet install

dotnet add package NBB.Messaging.OpenTelemetry

Publisher

To enable creating a publisher span, register the following publisher decorator in DI.

services.Decorate<IMessageBusPublisher, OpenTelemetryPublisherDecorator>();

The span is tagged with span.kind = "producer", component = "NBB.Messaging", message_bus.destination = the topic for the published message, nbb.correlation_id = the current correlation ID

Subscriber

To enable creating a subscriber span, add the following middleware in the messaging host pipeline:

.UsePipeline(pipelineBuilder =>
{
    pipelineBuilder
        ...
        .UseOpenTelemetry()
        ...
});

This span relates to the publisher span using a reference of type "follows_from". The following tags are associated with the span: span.kind = "consumer", component = "NBB.Messaging", peer.service = the name of the service that published the message , nbb.correlation_id = the current correlation ID
