Measurements made by the test
Measurement Description Measurement Unit Interpretation

Current VLB database requests

Indicates the number of database requests currently executing in this VLBinstance.


A consistently large value indicates a bottleneck at the database tier

VLB database request execution time

Indicates the average time it took to execute database requests which completed in the past minute. Response time includes the time for parsing the request, to get the cached stored procedure  (SP)information, executing the SAP, and the reading/parsing of the SP results.


A very high value of this measure indicates a performance bottleneck that requires further investigation.

VLB database requests handled

Indicates the number of requests to the database that have begun to execute in the past minute.



VLB SP execution time

Indicates the average time the ADO.NET took to execute a stored procedure in the past minute.
