Address Space CPU Utilization History attributes

The Address Space CPU Utilization History attribute group provides basic address space identifying information and CPU usage information for all address spaces over the specified near-term history time periods. It also provides historical enclave data.

ASID The address space ID of the job, in hexadecimal format.

CBP EAppl Time mSecs zCBP processor type not currently supported.

CBP Time On CP mSecs CBP time on CP in milliseconds.

CPU mSecs Excluding Home SRB (RMF metric) Total accumulated CPU time as sum of TCB time, global and local SRB time, and preemptable or client SRB time consumed within this address space in milliseconds.

CPU Percent (RMF metric) The percentage of CPU utilized by the address space over the interval. The value can exceed 100%. The maximum value is n00% where n is the number of processors (CPUs) assigned to the LPAR or image.

CPU Percent Excluding Home SRB Time (RMF metric) Percentage of total accumulated CPU time as sum of TCB time, global and local SRB time and preemptable or client SRB time, and enclave time consumed within this address space.

GCP mSecs Including Enclave Home SRB Time CPU milliseconds time spent on general purpose processors as sum of TCB time and enclave home SRB time.

GCP Percent Including Enclave Home SRB Time Percentage of CPU time spent on general purpose processors as sum of TCB time and enclave home SRB time.

IFA CP Time mSecs IFA processor type not currently supported.

IFA mSecs Including Enclave Home SRB Time IFA processor type not currently supported.

IFA on CP Percent (RMF metric) IFA processor type not currently supported.

IFA Percent Including Enclave Home SRB Time (RMF metric) IFA processor type not currently supported.

Job Additional SRB Service mSecs Preemptable or client SRB time consumed on behalf of this address space in milliseconds.

Job Additional SRB Service Percent (RMF metric) Cumulative Additional SRB Service percent to 1 decimal place for the address space since collection started. This will be (Job_Additional_SRB_Service_Time x 1000) / Job_Elapsed_Time. Since multiple CPs may be active this value can exceed 100%.

Job CPU Time (RMF metric) Cumulative CPU time in seconds with 2 decimal places for the address space since collection started. This will be a sum of Job_TCB_Time, Job_SRB_Time, and Job_Additional_SRB_Service_Time (ASST).

Job Name The name of the job, started task, TSO user, APPC address space, and so on, consuming CPU cycles. Valid value is a string, with a maximum of eight characters.

Job Preemptable Home SRB Service mSecs Preemptable or client SRB and enclave CPU time consumed within this address space in milliseconds.

Job Preemptable Home SRB Service Percent (RMF metric) Cumulative Preemptable Home SRB Service percent to 1 decimal place for the address space since collection started. This will be (Job_Preemptable_Home_SRB_Service _Time x 1000) / Job_Elapsed_Time. Since multiple CPs may be active this value can exceed 100%.

Managed System A z/OS operating system in your enterprise that is being monitored by an IBM® Z OMEGAMON AI for z/OS agent. Valid value is a character string with a maximum length of 32 bytes.

Recording End Time Recording time of data represented by a given row. For RMF-based near-term history this will be the time of the end of the RMF Monitor III reporting interval.

Recording Start Time Interval start recording time of data represented by a given row.

Recovery Boost Eligible Indicates whether the address space was eligible (YES/NO) for Recovery Process Boost during the interval.

RMF Status Status indications for availability of RMF and PROCU data.

Sample Period Sample period in seconds.

Service Class The service class name. This field will contain unavailable if the system is in compatibility mode.

Service Class Period The service class period. This field will contain unavailable if the system is in compatibility mode.

SMF ID SMF ID as defined in the IEASYM or IEASYS PARMLIB members.

SRB Percent (RMF metric) The percentage of CPU utilized by SRBs in the address space over the interval. The value can exceed 100%. The maximum value is n00% where n is the number of processors (CPUs) assigned to the LPAR or image.

SRB Time mSecs SRB time consumed in this address space by local or global SRBs in milliseconds.

TCB Percent (RMF metric) The percentage of CPU utilized by tasks in the address space over the interval. The value can exceed 100%. The maximum value is n00% where n is the number of processors (CPUs) assigned to the LPAR or image.

TCB Time mSecs TCB time consumed in this address space in milliseconds.

Time On CP Percent (RMF metric) The percentage of CPU time spent on general purpose processors as sum of TCB time, global and local SRB time, and preemptable or client SRB time consumed on behalf of this address space.

Total CPU mSecs Total accumulated CPU time as sum of TCB time, global and local SRB time, preemptable or client SRB time, and enclave time consumed within this address space in milliseconds.

Total Time On CP mSecs Total milliseconds spent on CP.

zCBP on CP Percent zCBP processor type not currently supported.

zCBP Percent Including Enclave Home SRB Time zCBP processor type not currently supported.

zIIP mSecs Including Enclave Home SRB Time Milliseconds of zIIP processor utilized by tasks in the address space, including enclave home SRBs over the interval.

zIIP On CP mSecs zIIP eligible CPU time used on CP in milliseconds.

zIIP On CP Percent (RMF metric) The percentage of CPU utilized by tasks performing zIIP work in the address space over the interval. The value can exceed 100%. The maximum value is n00% where n is the number of processors (CPUs) assigned to the LPAR or image.

zIIP Percent Including Enclave Home SRB Time (RMF metric) The percentage of zIIP utilized by tasks in the address space, including enclave home SRBs running on zIIPs, over the interval. The value can exceed 100%. The maximum value is n00% where n is the number of processors (zIIPs) assigned to the LPAR or image.
