Unformatted GTF trace output

This topic describes GTF output records that are not formatted by IPCS or other routines. You can use this information to write your own formatting or analysis routines.

Note: When GTF cannot obtain the data normally placed in fields of the following records, it signals this by placing one of the following values in the field

C'U/A'. Blanks are added on the right to fill out the field.
C'*'. Asterisks are replicated to fill out the field.

There are several types of output records:

Control records, see Control records.
Lost data records, see Unformatted lost event records.
User data record, see User data records.
System data records, see System data records.

The lost data, user data and system data records all contain optional fields, which are fields that only appear under certain conditions. The conditions are covered in the explanation for the fields. Make sure that your formatting or analysis routine takes these variable fields into account.

This section also describes the GTF system data records for individual events. See CCW trace record through SVC minimal trace record.
