Send telemetry trace via. rabbitmq and start a new scope with specific telemetry trace

[SalomonHenke]

Hey all. Limited knowledge of opentelemetry.

Is there a way to get a scopes telemetry trace? And then, is there a way to start a new scope via. the IServiceProvider and provide it with the telemetry id? Trying to keep a trace accros services. Idea was to send it via. the rabbitmq message / header param. But still need to be able to pick up the trace again + get the trace in the first place.

Images for reference. Havent found any obvious solutions online.

You do this in code using ActivitySource. Take a look at the documentation here.

An example of doing this with rabbitmq is here https://github.com/dotnet/eShop/blob/3b2515e69c16b1c2f64276aef3caeca5f947d399/src/EventBusRabbitMQ/RabbitMQEventBus.cs

Is this something which could be added to the RabbitMq Aspire Component at some point in the future, or is not how the team sees the Component responsibilities developing over time?

I think it depends on how this progresses rabbitmq/rabbitmq-dotnet-client#1261
