SAP Performance Statistics
You can access SAP performance statistics from the SAP Gateway framework for each OData request without having to activate the Performance Trace tool. To obtain the SAP performance statistics, you can add "?sap-statistics=true" at the end of the request URL, regardless of whether it is an HTTP method of type GET, POST, PUT, MERGE, PATCH or DELETE. Alternatively, you can enter (name=sap-statistics, value=true) in the HTTP request header. The setting in the URL is treated with higher priority that the setting in the HTTP header.
The SAP Gateway framework provides the performance statistics to the consumer
in the HTTP response header in the following format:
- HTTP Header Name: sap-statistics
- HTTP Header Value: total, fw, app, gwtotal, gwhub, gwrfcoh, gwbe, gwapp, gwnongw
Description:
- total: Total processing time
- fw: Framework
- app: Application
- gwtotal: Total processing time of the OData request
- gwhub: Processing time in SAP Gateway hub system
- gwrfcoh: RFC and network overhead for communication between the hub and backend system
- gwbe: Processing time in SAP Gateway framework in backend system (without application time)
- gwapp: Processing time in application (data provider)
- gwnongw: Processing time of applications called (referred to as non SAP Gateway since this processing time is not related to the SAP Gateway framework)
Note Due to SAP security policy, the SAP Gateway framework only provides the
performance statistics if the OData request could be processed successfully.
