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. For more information, see z/OS MVS Planning: Operations.

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.
