Documentation
Definition
This field specifies the average wait time per transaction for all requests from a particular service, a particular action, or a particular user to a component. The time is given in milliseconds.
Use
The wait time specifies how long a request has waited for example, in a dispatcher queue of a component for the resource that is responsible for processing. Resources can be threads or processes.
Within the DSR, the component measures the wait time in milliseconds and writes it in the statistics main record. The collector aggregates this data for the total wait time. The wait time can, however, only be determined in components in which resource assignment is performed using a dispatcher or similar process, and in which this assignment is not controlled directly by the operating system.
Dependencies
To be able to determine the average response time per transaction, the component must set the transaction start and transaction end indicators. In some components, the start and end of a business process cannot be identified using the incoming requests. The term "transaction" must be redefined in these components (see also the field Number of transactions).
Example
- For the Internet Transaction Server, the wait time is the time from the arrival of the request in the AGate Dispatcher to the acceptance of the request by a work thread.
- In SAP R/3 Systems, the wait time is the time that a request spends in the dispatcher queue of the application server before it is passed to a free work process.
