The following are considerations for the output parameters:
- Parameter 4
- Contains the one SMF record that is returned with all of the data
for the system. The SMFxxLEN field contains the length of the input
buffer, not the actual length of the record. If the buffer is over
64K, the record contains X'FFFF'. If necessary, you can calculate
the actual length of the record from the descriptor fields in the
record. The date and time fields (SMF79DTE and SMF79TME fields, respectively)
contain zeroes.
In case RMF™ was
not started since the last IPL, the following fields are set to these
values:
- SMF79IML
- X'FF'
- SMF79PTN
- X'FF'
- SMF79FLG
- LSB (bit 7) off
- SMF79PRF
- Bits 1 and 2 off
- Parameter 6
- Contains the current average standard CP utilization percent as
a binary fullword in the area provided. If RMF cannot determine the CPU utilization percent
on a PR/SM™ system because the
Monitor I CPU report is not active, RMF returns
a value of -1 (FFFFFFFF).
- Parameter 7
- Contains the page-ins per second rate as a binary fullword in
the area provided. This rate is for demand paging to DASD only. It
excludes swap-ins, VIO (virtual input/output), and hiperspaces.
- Parameter 9
- Contains the MVS™ view of
the CPU utilization if Monitor I CPU gathering is active. Otherwise
it is filled with the SRM view of the CPU utilization (source is CCVUTILP).
- Parameter 10
- Contains the current average ZAAP utilization percent as a binary
fullword in the area provided. If RMF cannot
determine the ZAAP utilization percent on a PR/SM system because the Monitor I CPU report
is not active, RMF returns a
value of -1 (FFFFFFFF).
- Parameter 11
- Same as Parameter 10, but for ZIIPs.
