Address Space CPU Summary History attributes

The Historical Address Space CPU Utilization attribute group provides basic address space identifying information and CPU usage information for all address spaces for all address spaces.

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

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

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.

CPU Percent 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 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.

TCB Percent 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.

SRB Percent 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.

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.

ASID The address space ID of the job (hexadecimal format).

Job CPU Time 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).

IFA on CP Percent The percentage of CPU utilized by tasks performing IFA 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 on CP Percent 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.

Job Additional SRB Service Percent 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 Preemptable Home SRB Service Percent 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%.

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

zIIP Percent Including Enclave Home SRB Time 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.

Time On CP Percent 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.

GCP Percent Including Enclave Home SRB Time 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.

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.

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

Sample Period Sample period in seconds.

zCBP on CP Percent zCBP on CP Percent. Possible values include: Unavailable=-1.

zCBP Percent Including Enclave Home SRB Time zCBP percent including enclave home SRB time. Possible values include: Unavailable=-1.
