Controlling system information recording

The system records information that is later used for billing, accounting, or diagnostics. Among the facilities that record system information are:

System management facilities (SMF)
System trace
The generalized trace facility (GTF)
Master trace
Component trace
The logrec recording medium

The system also records information in the system log and/or the operations log. See z/OS MVS Planning: Operations for more information.

In addition to these facilities, JES2 and JES3 have their own event trace facilities. These trace facilities are described in detail in z/OS JES2 Commands and z/OS JES3 Commands.
