Address Space CPU Summary History
This table provides basic address space identifying information and CPU usage information for a single address space as required in historical summary reports. Attributes with "RMF metric" in the description are obtained from RMF Monitor III. The interval for these attributes is the RMF Monitor III reporting interval. The Recording Start Time, Recording End Time, and Sample Period attributes show the reporting interval.
ASID Address Space ID in hexadecimal. The address space ID is a unique number assigned to an address space when it is created. It is used by MVS to differentiate between address spaces.
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 represents 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 It excludes the processor use by Enclave SRBs executing in the address space.
GCP Percent Including Enclave Home SRB Time (RMF metric) 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. This includes the processor use by Enclave SRBs executing in the address space.
IFA on CP Percent (RMF metric) 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 represents the number of processors (CPUs) assigned to the LPAR or image.
IFA Percent Including Enclave Home SRB Time (RMF metric) 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 represents the number of processors (CPUs) assigned to the LPAR or image.
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 (RMF metric) The name of the job, started task, TSO user, APPC address space, and so on. In the OMEGAMON Enhanced 3270 user interface this attribute is displayed as Address Space Name. Valid value is a character string of up to 8 bytes.
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 OMEGAMON for z/OS agent. Valid value is a character string with a maximum length of 32 bytes.
Recording End Time (RMF metric) 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 (RMF metric) 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. This attribute will not be presented in the workspace by default.
Service Class (RMF metric) The service class name. This field will contain Not available if the system is in compatibility mode. Valid value is a string, with a maximum of eight characters.
Service Class Period (RMF metric) The service class period. This field will contain Not available if the system is in compatibility mode. Valid range is 0-2147483647.
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 represents the number of processors (CPUs) assigned to the LPAR or image.
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 represents the number of processors (CPUs) assigned to the LPAR or image.
Time On CP Percent (RMF metric) 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.
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 represents 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 represents the number of processors (CPUs) assigned to the LPAR or image.
