I've started a new question on your behalf so we can get a fresh look at what is happening in your system. If need be, I can help you get a Support case created and work with you to diagnose any problems. For now, let's look at the behavior you are seeing.
The original post can be found here:
You are running a 10.4.1 Full Stack (formally known as a Web-GIS) with GeoEvent. All of the output connectors display a 0 count for the received Geoevents, and have been for a long period of time. Normally this still indicates a RabbitMQ or larger issue with the transport system behind GeoEvent. What we can do is start at the basic level here and see if we can determine the cause.
If you're able to, please attach a zipped copy of the GeoEvent log files. These can be found at C:\Program Files\ArcGIS\Server\GeoEvent\data\log. They are quite verbose, and I'm hoping they can show us what is occurring.
Also, have you noticed this as a recent error, or has it been present since the initial installation?
