This appendix provides reference information about CICS® statistics. For information about the interpretation of CICS statistics, see Using CICS statistics.
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 the CICS Customization Guide.
Each area of CICS statistics is listed below 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:
|
Statistics areas are listed alphabetically.
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 the CICS Operations and Utilities Guide. 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 desired 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.
Within each of the following sections, the meaning of the summary statistics is given. 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.
