ArcGIS GeoEvent Server allows you to simulate, log, and sample and display real-time data.
GeoEvent Simulator is a Windows application that allows you to simulate and send real-time data to GeoEvent Server. GeoEvent Simulator, as a client, connects to a transmission control protocol (TCP) socket hosted by a receive text from a TCP socket input. Simulated event data is sent as delimited text to the input, which adapts the data to create an event record that can be processed in a GeoEvent Service.
GeoEvent Logger is a Windows application that allows you to view logs of event records processed by GeoEvent Server. It displays and logs event records processed by a GeoEvent Service and sent to a TCP or text output for delivery to external components. GeoEvent Logger hosts TCP sockets to which the push text to an external TCP socket output can connect.
GeoEvent Sampler is a utility in the service designer of GeoEvent Manager that allows you to sample, display, and visualize event records as they are processed in a GeoEvent Service. After selecting a route (or connection) between elements in a published GeoEvent Service, the sampler window displays a sample of event records on that route as either prettified JSON or delimited text.
