OpenTelemetry business transactions only show HTTP Post

Björn.Wenzel
Creator

For 3 Spring Boot applications (2 classic servlet and one spring cloud gateway in front) I have enabled OTEL and see the first metrics arriving successfully in my Controller.

Due to whatever reasons it seems that the Business Transactions only show that the app is NodeJS & the name of the Transaction is HTTP Post. I don't see the different routes that are available via the gateway & routed to the 2 classic spring boot applications.

For a short test I also reconfigured the collector to log every request instead of forwarding it to the controller, please see attached details about the request:
