This table monitors service class period performance relative to goals.
Actual Host The host actual value, either a response time in milliseconds or a percentage, based on the goal type. The value in this column is 0 if the goal type is Discret or Sysgoal. A valid value is an integer.
Average Response Time The average host response time of transactions in this service class. A valid value is an integer.
Average Storage The average storage for this service class, excluding private virtual storage allocated in this service class through cross-memory services on behalf of other service classes. A valid value is an integer.
Class Flag Categorizes the service class based on the general types of transactions managed by it. A valid value is an integer. Values appear on the workspace as follows:
CPU Critical Indicates whether address spaces running in a service class are CPU protected or "critical". A valid value is an integer. Values appear on the workspace as follows:
CSS Priority
The average channel subsystem (CSS) DASD I/O priority observed for address spaces
with I/O Activity for a given Service Class Period (SCP).
For SCPs with no observed I/O activity, or if CSS I/O priority management is disabled
in the CPC Reset Profile, a value of Unavailable
will be reported.
A valid value is an integer, displayed as a hexadecimal string. The range for this value is from 0 to 255 or X'00' to X'FF'.
A value of 0 indicates "Unavailable".
Duration The number of processor service units the period may use before work is passed to the next period. A valid value is an integer.
Goal Importance The importance of this goal for the service class period. Goal importance for the service class is set as part of the Workload Manager (WLM) policy. When WLM cannot satisfy all goals, it tries to meet goals for more important service class periods first. A valid value is an integer. Values appear on the workspace as follows:
Goal Percentile The percentage of work in the service class period (that is, the percentage of transactions) that completed within the expected response time (or goal value). Goal percentile is valid for percentile response time goals only. This value is set by the system administrator for this service class when the WLM policy is defined. It is not a measured result. A valid value is an integer. The range for this value is from 0 to 100.
Goal Type The type of goal for the service class period. A valid value is an integer. Values appear on the workspace as follows:
Goal Value A value representing the goal assigned to the service class period. A valid value is an integer. Values corresponding to goal types appear on the workspace as follows:
I/O Priority The average I/O Subsystem priority observed for address spaces with I/O activity for a given Service Class Period (SCP). For Service Class Periods with no observed I/O activity, or if I/O priority management has been set to NO in the Workload Manager (WLM) policy, a value of Unavailable will be reported. A valid value is an integer, displayed as a hexadecimal string. The range for this value is from 0 to 255. A value of 0 indicates "Unavailable".
I/O Rate The number of I/Os per second as a measurement of data set and JES spool I/O activity for all data sets associated with this service class period. A valid value is a number to one decimal place accuracy.
Managed System The z/OS operating system in your enterprise that an OMEGAMON for z/OS agent is monitoring. A valid value is a string of up to 32 characters.
Percent CPU The percentage of CPU time consumed by this service class period. A valid value is a number to one decimal place accuracy. The range for this value is from 0 to 500.0.
Percent zCBP/zAAP The percentage of System z Container Based Processor (zCBP) or zSeries Application Assist Processor (zAAP) resource used by the service class period. The value is normalized to reflect the faster speed of a zCBP/zAAP compared to a general purpose processor if the LPAR is dispatched on a restricted processor. A valid value is a number to one decimal place accuracy.
Percent zCBP/zAAP on CP The percentage of standard processor (CP) resource used by the service class period performing work eligible for a System z Container Based Processor (zCBP) or zSeries Application Assist Processor (zAAP). This occurs when IFACrossOver=YES is specified in IEAOPTxx. A valid value is a number to one decimal place accuracy. A value of -1 indicates "Ineligible"; the service class specialty processors are not to receive help from standard processors regardless of the system HONORPRIORITY setting..
Percent zIIP The percentage of System z Integrated Information Processors (zIIP) resource used by the service class period. The value is normalized to reflect the faster speed of a zIIP compared to a standard processor if the LPAR is dispatched on a restricted processor. A valid value is a number to one decimal place accuracy.
Percent zIIP on CP The percentage of standard processor resource used by the service class period performing work eligible to run on System z Integrated Information Processors (zIIP). A valid value is a number to one decimal place accuracy. A value of -1 indicates "Ineligible"; the service class specialty processors are not to receive help from standard processors regardless of the system HONORPRIORITY setting..
Performance Index The performance index for the host; a measure of how well a service class period is performing relative to its goal. A performance index of less than 1 indicates that the period is performing better than its goal. A performance index of 1 indicates the period is meeting its goal. A performance index greater than 1 indicates the period is performing worse than its goal. A valid value is a number to two decimal places accuracy. The range for this value is from 0 to 100.00.
Average and percentile response time performance indexes are calculated by dividing the actual values by the goal values. The velocity performance index is calculated by dividing the goal value by the actual value.
Period
The service class period number.
When specifying a situation where the values should represent the service class as
a whole, specify a value of SUM
.
A valid value is an integer. The range for this value is from 1 to 8.
Promoted Percent The percentage of time the service class workload ran at a promoted dispatching priority. A valid value is a number to three decimal places accuracy.
Resource Group A group that specifies how much processor capacity is available to one or more service classes. Resource groups are used to limit or guarantee some amount of processing capacity to a service class or set of service classes. A valid value is a string of up to 8 characters.
Service Class The name of the service class being reported on. A service class represents a uniquely-named group of work having common performance requirements such as similar performance goals, availability requirements, resource requirements, or business importance. A valid value is a string of up to 8 characters.
Service Class Description The text describing this service class as specified in the active service policy. A valid value is a string of up to 32 characters.
Storage Critical Indicates whether address spaces running in a service class are storage protected or "critical". A valid value is an integer. Values appear on the workspace as follows:
Workload The name of the workload that contains the service class. A valid value is a string of up to 8 characters.
Workload Description The text describing this workload as specified in the active service policy. A valid value is a string of up to 32 characters.

zCBP/zAAP Service Units The number of System z Container Based Processor (zCBP) or zSeries Application Assist Processor (zAAP) service units as standard CP service units. A valid value is an integer.
zIIP On CP Service Units The number of service units consumed by the service class period performing work eligible for System z Integrated Information Processors (zIIPs) on a standard processor. A valid value is an integer.
zIIP Service Units The number of service units consumed by the service class period performing work on a System z Integrated Information Processor (zIIP). A valid value is an integer.
