Processors are elements in a GeoEvent Service that perform real-time processing of GeoEvents as they are received. In ArcGIS GeoEvent Manager, a processor can be added to a GeoEvent Service by dragging or double-clicking the Filter element from the New Elements list. The processor can be configured to support real-time event data processing workflows.
For details on processors, see Introduction to processors.
Step-by-step instructions for adding processors to a GeoEvent Service are included in the Introduction to GeoEvent Server Tutorial. You can also access the tutorial from GeoEvent Server tutorials.
