CICS statistics data section

The format of the CICS statistics data section is shown in Figure 122.
If the data records are incomplete, the flag field SMFSTICD is set to ‘YES’. In this

case, the statistics data section is not present.

For complete data records, the statistics data section is made up of one or more
statistics data records. There are different formats of data records. Each has a
common format for the first 5 bytes. These 5 bytes are described in the extract from
copy book DFHSTIDS in Figure 123.

STILEN

is the length of the data record.

STID

identifies which type of statistics record you have (see Figure 124 on page 775).

You can use the STID symbolic name or value to determine which copy book to
use when processing the statistics data records. For details about the
relationship between the STID name or value and the copy book, see
