CICS statistics in DSECTs and DFHSTUP report
The main reference information for the CICS® statistics lists them as they are presented in the report from the DFHSTUP utility, and in the statistics DSECTs.
All five types of CICS statistics record (interval, end-of-day, requested, requested reset, and unsolicited) present information as SMF records. The numbers used to identify each SMF statistics record are given in the DFHSTIDS copybook. Programming information about the formats of CICS statistics records is given in Writing statistics collection and analysis programs.
For resource types that are supported as private resources for applications deployed on platforms, statistics for both public and private resources are reported in the output from the DFHSTUP utility. The statistics for public resources and the statistics for private resources are mapped by separate DSECTs, and are also reported separately by DFHSTUP.
Format in which CICS statistics are listed
Statistics areas are listed alphabetically. Each area of CICS statistics is listed in the following format:
| DFHSTUP name | Field name | Description |
|---|---|---|
| DFHSTUP name is the name as it appears on the DFHSTUP report. | Field name is the name as it appears in the DSECT mapping this data. | Description is a brief description of the statistics field. Reset
characteristic: Reset characteristic of the statistics field at a statistics interval
collection. The values can be:

Summary report
The Statistics Utility Program (STUP) provides a summary report facility that can be selected using a DFHSTUP control parameter. Information on how to run DFHSTUP is given in Statistics utility program (DFHSTUP). When selected, the summary report is placed after all other reports. The DFHSTUP summary report facility summarizes (totals, peaks, and averages) the interval, unsolicited, requested reset and end-of-day statistics on an applid by applid basis. Requested statistics are not involved in the production of the summary report.
The summary report feature uses all of the appropriate statistic collections contained on the SMF data set. Therefore, depending on when the summary report feature is executed and when the SMF data set was last cleared, summary reports may be produced covering an hour, a week, or any period of time. Note that due to the potential magnitude of the summary data, it is not recommended that a summary period extend beyond one year.
Because the summary statistics are computed offline by the DFHSTUP utility, the summary statistics are not available to online users. Due to the potential magnitude of the summary data, and due to limited page width, summary data may be represented as a scaled value. For example, if the total number of terminal input messages is 1234567890, this value is shown as 1234M, where 'M' represents millions. Other scaling factors used are 'B' for billions and 'T' for trillions. Scaling is only performed when the value exceeds 99999999, and only then when page width is limited, for example in terminal statistics.

Server statistics not in DFHSTUP
The DFHSTUP summary report does not include the statistics obtained for the shared temporary storage queue server, the coupling facility data tables server, and the named counter sequence number server.
- Shared temporary storage queue server statistics
- Shared temporary storage queue server statistics are provided by the AXM page pool management
routines for the pools AXMPGANY and AXMPGLOW.
For more information, see Shared temporary storage queue server statistics.
- Coupling facility data tables server statistics
- Coupling facility data tables server statistics are provided by the AXM page pool management
routines for the pools AXMPGANY and AXMPGLOW.
For more information, see Coupling Facility Data Table Pools report.
- Named counter sequence number server statistics
- Named counter sequence number server statistics are provided by the AXM page pool management
routines for the pools AXMPGANY and AXMPGLOW.
For more information, see Named counter sequence number server.
