After you acquire the statistics from the contents of a log stream, you can produce a report.
Use the following utilities to produce a report:
IXGRPT1 provides information concerning how much data is being moved to the offload data sets within an SMF interval. This utility creates a report using SMF 88 records.
IEBGENER dumps the contents of a log stream to a sequential data set. No data is actually copied because the output is going to DUMMY. The exit program produces information about the log stream being read.
The following is a sample IEBGENER job:
//jobcard //* //GENER1 EXEC PGM=IEBGENER //* //SYSUT1 DD DISP=SHR,DSN=log.stream.name, // SUBSYS=(LOGR,GSVXLGEX), // DCB=BLKSIZE=32760 //* //SYSPRINT DD SYSOUT=* //SYSUT2 DD DUMMY //SYSIN DD DUMMY /*
Sample output from the IEBGENER job:

Indicates the specified log stream was opened.
Defines the list of options used on the SUBSYS= parameter.
Displays the date and time of the oldest and youngest records read.
Displays the block ID of the oldest and youngest records read.
Displays the number of records read of a specific SMF type. SMF records created by CA SYSVIEW get listed specifically. All others get listed as "Other".
