Our production GeoEvent Server is at 10.8.1 (non-federated) server in the DMZ. We've set up a GeoTab stream service which is not streaming the actual geometry when we subscribe to it. We set up a .csv output file and have confirmed it's writing data per the GeoEvent Definition used to publish the service. We also set up a stream service to the ISS feed per Esri's GeoEvent stream services tutorial, it also will not stream the actual geometry. The logs show no errors. The logs show only INFO entries such as "Stream null/ISS-stream-service-out is found in memory." We've applied the latest security patches, and the odd thing is, we have the same implementation in our QA environment and there are no issues with the stream services.
