本文介绍了一个用于定期汇总和分析交易步骤中产生的单一记录的程序RSCOLL00。该程序作为后台作业每小时运行一次，并将压缩后的统计数据保存到SWNCMONI表中。通过工作负载监视器可以查看收集器的日志文件并调整设置。

To ensure that the statistical single records generated and saved for each transaction step are regularly collated in profiles, the RSCOLL00 program must be scheduled to run every hour as a background job (generally under the name SAP _COLLECTOR_FOR_PERFORMANCE) . The compressed statistics are stored in the SWNCMONI table. You can display and modify the parameters of the collation in the workload monitor. In the EXPERT role, select COLLECTOR AND PERFORMANCE DATABASE • PERFORMANCE DATABASE • MONITORING DATABASE • REORGANIZATION. Under STANDARD RETENTION PERIODS, you can enter the retention periods for complete analyses before they are automatically deleted. Under RETENTION PERIODS OTHER, you can enter the retention period for data displayed under the workload monitor menu option LOAD HISTORY.

Logs are written for each run of the RSCOLL00 program, which you can use for troubleshooting. You can view the log in the workload monitor via the menu path COLLECTOR AND PERFORMANCE DATABASE • WORKLOAD COLLECTOR • LOG. You can find explanations of the functions and settings of the data collector at SAP Help
