Offsets
Dec Hex Type Len Name (Dim) Description
0 0 Structure 140 SYTPRP Start of monitor record
0 0 Character 0 SYTPRP_MRHDR Record header. See MRRECHDR
for details.
0 0 Character 20 MRHDR
0 0 Unsigned 2 MRHDRLEN record length in bytes
2 2 Unsigned 2 MRHDRZER field of zeros
4 4 Unsigned 1 MRHDRDM domain identifier
5 5 Unsigned 1 *
6 6 Unsigned 2 MRHDRRC record identifier
8 8 Character 8 MRHDRTOD Time at which this record
was built. In time-of-day
(TOD) clock format. See IBM
System 370 XA Principle of
Operation for explanation of
format.
16 10 Character 4 *
20 14 Character 0 MRHDR_END End of header
20 14 Unsigned 2 SYTPRP_PFXCPUAD Real processor's CPU
address
22 16 Unsigned 2 SYTPRP_PLSCUHAF Count of times a VMDBK was
dispatched with 'hard
affinity' (i.e., dedicated to
this processor)
24 18 Character 8 SYTPRP_PFXPRBTM Total CPU time spent in
emulation mode on this
processor for all users
32 20 Character 8 SYTPRP_PFXUTIME Total CPU time spent on
this processor which was
charged to users. It includes
both time spent running the
guest and time that CP spends
on behalf of a user doing
such things as instruction
simulation or page
translation. This is in CPU
time, not elapsed (or wall
clock) time.
40 28 Character 8 SYTPRP_PFXTMSYS Total CPU time spent on
this processor which has been
charged to the system instead
of the user. In general, this
is processing that is
inappropriate to charge to
any one particular user.
Examples include portions of
the following functions:
scheduling decisions,
handling interruptions,
monitoring, and page
migration.
48 30 Character 8 * Reserved for IBM use.
Previous field is no longer
meaningful. (SYTPRP_PLSVFVTM)
56 38 Character 8 * Reserved for IBM use.
Previous field is no longer
meaningful. (SYTPRP_PLSVFOTM)
64 40 Unsigned 4 * Reserved for IBM use.
Previous field is no longer
meaningful. (SYTPRP_PLSVFLOD)
68 44 Character 8 SYTPRP_PFXTOTWT Total system wait time on
this CPU (includes both
active wait and enabled CPU
wait). It is the time this
CPU had no work to do,
measured in CPU time.
76 4C Unsigned 4 SYTPRP_PFXRUNCI Count of interceptions from
SIE on this processor. It
does NOT include
interceptions from SIE
instructions issued in order
to run a 'Vguest', i.e., a
guest of a guest, during
guest SIE simulation. It does
NOT include interceptions
handled by the fast-path
simulation support code.
80 50 Unsigned 4 SYTPRP_PFXRUNPF Count of host page faults
on this processor resulting
from guest references to
storage paged out by CP. Does
not include faults on RCP
pages
84 54 Unsigned 4 SYTPRP_PFXRUNCP Count of SIE instructions
on this processor. It
does not include instructions
issued in order to run a
'Vguest', i.e., a guest of a
guest, during guest SIE
simulation. It does not
include instructions issued
following a successful
fast-path simulation support
code.
88 58 Unsigned 4 SYTPRP_CALFSTPH Count of fast-path
instruction simulations.
PFXFSTSG + PFXFSTXC +
PFXFST44
92 5C Character 8 SYTPRP_PFXSPINT Elapsed time in formal spin
locks on this real CPU
starting at zero and counting
upwards. This is measured in
TOD clock units since system
IPL.
100 64 Unsigned 4 SYTPRP_PFXSPINC Count of spin lock requests
on this real CPU since IPL
that were not granted
immediately. The lock was
obtained only after spinning.
104 68 Unsigned 1 SYTPRP_PFXCPUTY CPU Type. Valid values:
X'00' - General Purpose (CP)
X'02' - zSeries Application
Assist (zAAP) X'03' -
Integrated Facility for Linux
(IFL) X'04' - Internal
Coupling Facility (ICF) X'05'

105 69 Character 3 * Reserved for IBM use
108 6C Unsigned 4 SYTPRP_PFXFSTPX Count of fast path
processing of partial
execution interrupts
112 70 Unsigned 4 SYTPRP_PFXFSTXC Count of fast path
reflections of guest External
Call interrupts
116 74 Unsigned 4 SYTPRP_PFXFSTSG Count of fast path
simulations of SIGP External
Call instructions
120 78 Unsigned 4 SYTPRP_PFXFST44 Count of fast path
simulations of Diagnose X'44'
instructions
124 7C Unsigned 4 SYTPRP_PLS9CNR Count of times a guest
issued Diagnose x'9C' and the
target was in a VMDSTATE <
VMDREADY
128 80 Unsigned 4 SYTPRP_PLS9CWT Count of times a guest
issued Diag x'9C' and the
target was found in wait
state (PSW.W=1)
132 84 Unsigned 4 SYTPRP_PLS9CSWT Count of times a guest
issued Diag x'9C' and the
issuer had to soft-wait on
the target.
136 88 Unsigned 4 SYTPRP_PLS9CDSP Count of times a guest
issued Diag x'9C' and the
target was already dispatched
