From the point of view of the end user, response times are one of the most important criteria for the performance of systems and databases. In the context of interactive reporting, there are four reports that give you a quick overview of the development of these metrics and their relationship over time:
Workload (
)The report shows the number of dialog steps, and the mean response time, graphically. The metrics are taken from the CCMS monitoring infrastructure; for more information about the dialog response time and number of logged-on users, see Dialog Overview Monitor, where these performance values are described in the context of the Alert Monitor.
Response Time Distribution (
)In addition to the average response time, the distribution of the response times is important for judging the system performance. The response time distribution specifies how many dialog steps were performed with which response time. The metric is taken from the ABAP statistics records; for more information, see Displaying Response Time Distribution, where this performance value is described in the context of the Workload Monitor.
Response Time Composition (
)This report outputs the component parts of the response time. You can then determine which functional area is responsible for any poor performance. The proportion of the following components of the response time is displayed. The number of dialog steps is also shown, to help you to interpret the values shown:
Database time
Wait for free work process
Load and generate
Processing time
External call (roll)
Enqueue time
You can also determine, for example, which instances, task types, transactions or application components are to be taken into account for the response time component display, using filters.
Database Performance (
)This report displays the time per access, and the number of accesses, classified by read and write access, which gives you an overview of the performance and usage of the database.
Note
For information about how you can specify the desired systems and the time interval to be displayed, and how to call interactive reporting, see Using Interactive Reporting.
For information about the different display options for the reports for ABAP systems with regard to metrics, threshold values, and instances, see Interactive Reports for ABAP Systems.
