Processing CICS statistics

You can process CICS® statistics in the following ways:

  1. Use the CICS DFHSTUP offline utility. DFHSTUP, prepares and prints reports offline, using the CICS statistics data recorded on the MVS™ system management facilities (SMF) SYS1.MANx data sets. For guidance about retrieving CICS statistics from SMF, and about running DFHSTUP, see the CICS Operations and Utilities Guide.
  2. Create your own statistics reports using the DFHSTUP extract statistics reporting facility. This provides a DFHSTUP exit that sends CICS statistics data to a user program that can process statistics records to create tailored reports. These reports should be easy to review on a daily basis; avoiding the need to work through large amounts of data to determine if some corrective or preventative tuning action is required. It should also be possible to identify the specific CICS regions, the time of day, and the type of CICS resources that may require further specific in-depth performance analysis. DFH0STXR is a sample program designed to exploit the extract reporting function. You can use the sample program as supplied, or as a model on which to base your own programs. For guidance about using the extract reporting facility, see the CICS Operations and Utilities Guide.
  3. Write your own program to report and analyze the statistics. For details about the statistics record types, see the assembler DSECTs named in each set of statistics. For programming information about the formats of CICS statistics SMF records, see the CICS Customization Guide.
  4. Use the sample statistics program (DFH0STAT). You can use the statistics sample program, DFH0STAT, to produce online reports from the CICS statistics data. The program demonstrates the use of the EXEC CICS INQUIRE and EXEC CICS COLLECT STATISTICS commands to produce an analysis of a CICS system. You can use the sample program as provided or modify it to suit your needs. For more information, see Appendix E. The sample statistics program, DFH0STAT.
  5. Use CICS Performance Analyzer to produce reports and extracts using CICS Monitoring Facility performance and exception records. For more information, see CICS Performance Analyzer for z/OS (CICS PA).
  6. Use Tivoli® Decision Support to process CICS SMF records to produce joint reports with data from other SMF records. For more information, see Tivoli Decision Support for z/OS.
