Configuring Performance Monitor Collectors in SAP
Configuring Performance Monitor Collectors in SAP
- Start the workload monitor by calling transaction ST03N.
- Choose the Expert User Mode.
- In the Functions subscreen, choose Collector & Perf. Database ® Perf. Monitor Collector ® Execution Times.
- The system displays the Contents of table TCOLL screen.
The system displays an execution timetable for the various collectors. Each line specifies for one collector on which days of the week and at what times of the day the corresponding report is executed. For an execution, both conditions (week day and time) must be fulfilled.
In the System column, you can specify on which instance the report should run:
| Entry in System Column | Meaning |
| C | The report runs on the central instance of the system |
| * | The report runs on every instance of the system (the background job SAP_COLLECTOR_FOR_PERFMONITOR distributes the report) |
| E | The report runs on the instance of a system on which the enqueue process is running; this is important for systems in which the central instance shares a host with other instances |
5. If you want to change the execution time, choose Table Maintenance.
6. The system displays the Performance Collector: TCOLL maintenance screen. Every line contains the execution time of a report.
- In the column Days M-W-F-S, you specify on which days of the week the report should be executed by entering seven characters. Enter a character for every weekday, beginning with Monday:
X (the report should be executed on the corresponding weekday) or a space (the report should not be executed on the corresponding weekday).
- Make an analogous specification in the column Hours 0-2-4-6-8-0-2-4-6-8-0-2, in which the 24 individual characters stand for the hours of a day from 0000 hours to 2300 hours.
- In the column R, you specify how often the report should be executed per rotation.
- In the Alternative System column, you specify on which instance the report should be executed.
