SMF type 30 (subtype 4) records contain useful
information on the resource consumption of a particular job step. These include
CPU time (total, and broken down by field), elapsed time, EXCPs (total, and
broken down by device), and device connect time.
These SMF records provide a wealth of performance data,
which is often difficult to analyse in its raw form. You need to convert this
raw data into processed data that can be used for trend analysis and management
reports. If you do not have access to a performance analysis and reporting
product, you can use the DFSORT editing functions in combination with the
reporting capabilities of ICETOOL or OUTFIL to generate performance data reports.
The INCLUDE/OMIT, OUTFIL, and INREC/OUTREC control statements are helpful in
selecting the specific fields of the particular SMF, RMF, or other data records
to be analysed. ICETOOL or OUTFIL can then be used to generate printable
reports from the resulting raw data. See z/OS DFSORT Application Programming
Guide (SC26- 7523-00) for more information about ICETOOL, OUTFIL, and editing
functions.
ICETOOL was used to select and display SMF type 30 (subtype 4) records below.
