6.2.1 SMF Recording Options

This section describes the parameters and options that
control the record types collected by SMF.  You should take
care in specifying the SMF recording parameters and options
at your site.  By carefully tailoring the SMF recording to
meet your installation's needs, you will minimize the system
overhead and DASD space requirements of SMF.

There are several options available to tailor SMF data
measurement, collection, and recording.  These options are
invoked by parameters contained in the SMFPRMxx member of
SYS1.PARMLIB.  They are involved with internal data
collection, record formatting, or SMF writer.  The options
that specify record type and subtype selection as well as
interval recording and operator prompting are important to
the implementation of the CA MICS Batch and Operations
Analyzer.  In addition, there are a number of exits provided
by SMF for manipulating SMF data before it is written to the
SMF data sets.  More information about these parameters and
options can be found in the System Management Facilities
(SMF) Manual at:
