2.3.3 Standard Output

The Auxiliary Storage Management reports give you the
capability to track the allocation of auxiliary storage at a
monthly, weekly, daily, or hourly level.  The reports use
data from the page/swap data set files and the device
activity files from the RMF SCP and HAR Information Areas to
report on the activity levels and response of the ASM
subsystem.  The device activity files are used to obtain the
I/O queue time for each of the page/swap devices, because the
I/O service time in the page/swap files includes only the I/O
transfer time.

To provide different views of the ASM information, the
reports summarize the ASM information by page space type
(common, pageable link pack area (PLPA), local, duplex, and
swap) device type, or data set name.

The following sections describe the report formats of the ASM
Page/Swap Activity and the ASM Page/Swap Response Time
