Several adapters have been created using the adapter toolkit and consist of various modules (transporters, formatters, ESPPublisher or ESPSubscriber). See Preconfigured Adapters Included with the Adapter Toolkit in the SAP Event Stream Processor: Building Custom Adapters for a full list of these adapters. Note that:
  • Output transporter modules that run in streaming mode do not report statistics to the _ESP_Adapter_Statistics metadata stream.
  • Output transporter modules that run in row mode report statistics to the _ESP_Adapter_Statistics metadata stream.
  • Input transporter modules that run in either streaming or row mode report statistics to the _ESP_Adapter_Statistics metadata stream.
See Transporters Currently Available from SAP and Formatters Currently Available from SAP in the SAP Event Stream Processor: Building Custom Adapters to determine in which mode a module operates. See Adapter Controller Parameters for the adapter of your choice in the SAP Event Stream Processor: Adapters Guide for details on tuning the frequency that the adapter reports its statistics to the _ESP_Adapter_Statistics metadata stream.

For information on the statistics that each adapter publishes, see the SAP Event Stream Processor: Adapters Guide.
