Measures reported by BWOHDStatTest

An open hub destination is created in order to transfer BW data to a flat file, database table or directly to a third-party tool. The open hub destination is the object that allows you to distribute data from a BI system to SAP/non-SAP data marts, analytical applications, and other applications. It ensures controlled distribution across multiple systems. The open hub destination defines the target that the data is relayed to. Any objects supported by the data transfer process can be used as open hub data sources. Database tables and flat files can serve as open hub destinations. The database table can be located in SAP BW∕4HANA or in another database system that is supported by SAP NetWeaver. The data can be extracted from the database to a downstream system. If the requests to the open hub destination cannot be processed or takes too long to be processed or if the requests are error-prone, then data flow through the open hub destination may either be too slow or may terminate inadvertently. This may affect the data transfer to a larger extent. To ensure smoother data transfer through the open hub destination, it is necessary to keep track on the requests to the open hub destination and the time taken to process the requests. Similarly, error-prone requests when left unnoticed will adversely affect the functioning of the SAP Business Warehouse Instance. Frequent checks for errors will help administrators in maintaining the health of the SAP Business Warehouse Instance. The BWOHDStatTest test helps administrators in this regard!

This test reports the total requests sent to the open hub destination and the count of lines read by the open hub destination per request. Using this test, administrators can figure out the response time of the open hub destination for each request. Administrators are also pointed to error prone requests so that they can figure out such requests and identify problematic conditions before end users start complaining.

Outputs of the test : One set of results for the target SAP Business Warehouse Instance being monitored.

The measures made by this test are as follows:

Measurement Description Measurement Unit Interpretation
Requests Indicates the total number of requests to the open hub destination during the last measurement period. Number  
Request_rate Indicates the number of requests sent to the open hub destination per minute. Requests/min  
Error_requests Indicates the total number of error-prone requests to the open hub destination during the last measurement period. Number Ideally, the value of this measure should be zero.

The detailed diagnosis of this measure lists the INFOSPOKE, INFOSPOKE version, Request state, Response time, Start time, End time, Lines read, Datasource, Destination Type, Destination, Job, Log ID, Request ID and Update Mode of each error-prone request.
Error_request_rate Indicates the number of error-prone requests to the open hub destination per minute. Errors/min Ideally, the value of this measure should be zero.
Response_time Indicates the time duration for which a request was processed by the open hub destination. Seconds/execution A sudden/gradual increase in the value of this measure indicates a problematic condition wherein the open hub destination may be encountering issues in servicing requests to transfer data to other sources.

The detailed diagnosis of this measure lists the INFOSPOKE, INFOSPOKE version, Request state, Response time, Start time, End time, Lines read, Datasource, Destination type, Destination, Job, Log ID, Request ID and Update mode of the requests that were slow.
Average_lines_read Indicates the count of lines read by the open hub destination upon a request during the last measurement period. Lines/request
