Most common way to create collections is by label, component type, or possible by name. see https://doc.arcgis.com/en/monitor/latest/get-started/windows/collections.htm . Are you asking about the data mode? https://doc.arcgis.com/en/monitor/latest/get-started/windows/arcgis-monitor-information-model.htm
