An analysis always displays an aspect of the system load. One of these aspects is the question of how the load is distributed over the individual service types. A service type characterizes the type of processing of a request in a component; it can be compared to the task type in SAP R/3 statistics records. For example, there are the types Dialog, Background, and Update there.

The Internet Transaction Server, as the first DSR instrumentation, has the following service types:

• SAP GUI for HTML emulates SAP R/3 transaction screens dynamically in Web browsers by automatically mapping the SAP R/3 screen elements into HTML using the Internet Transaction Server.

• FlowLogic allows the user to call applications from the Web browser. The following applies:

• The business logic is defined in remote function modules or BAPIs
• The dialog flow is defined in flow files and is specified by the user during runtime
• The presentation is defined in HTML templates

• Internet Application Components (IAC) are Internet-capable SAP R/3 transactions, function modules, and reports that can be called from a Web page. The execution is performed with the help of the Internet Transaction Server.

• WebRFC allows the user to call SAP R/3 function modules from the Web browser.

• Unknown is the action type if the action is running is one of the Mixed Modes (ifor example, controls of the SAP GUI for HTML are displayed on IAC Templates).

The Internet Transaction Server is currently the only non-SAP R/3 component type for which statistics records are written that can be analyzed in the global workload monitor. We plan to include other component types in the future.

The output area displays how the workload is distributed over the various service types. To obtain a description of a column, select the corresponding column and use the F1 help.

You can select how you want to display the workload using the tab pages:

• Average Values per Step
• Average Values per Transaction
• Total Times
• Share of Response Time
