DSECT NAME - SYTPRP FUNCTION - Map a Monitor record. LOCATED BY - Through the Monitor control area REFERENCED CONTROL BLOCKS - MRRECHDR Monitor Record Header NAME - MRSYTPRP DESCRIPTIVE NAME - Monitor Sample Record Domain 0 - System Domain Record 2 - Processor Data (Per Processor) DESCRIPTION - Real System or CPU operation exception. A separate record is generated for each online processor.

Offsets Dec Hex Type Len Name (Dim) Description 0 0 Structure 104 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 particular user. Examples include portions of the following functions: scheduling decisions, handling interruptions, monitoring, and page migration. 48 30 Character 8 SYTPRP_PLSVFVTM Amount of CPU time this processor has been using the real vector facility while in SIE 56 38 Character 8 SYTPRP_PLSVFOTM Amount of CPU time that this processor has spent on switching vector users 64 40 Unsigned 4 SYTPRP_PLSVFLOD Cumulative count of the times CP loads the vector registers from where they were saved on guest-owned storage frames. 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 instructions from SIE 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 Character 0 SYTPRP_END
