The predefined Service Level Analysis workspace shows the overall performance of each service class defined within a workload. A high percentage of time spent for different types of waits can indicate potential problem areas. It also shows the response times for each service class.
The predefined Service Level Analysis workspace contains the following views:
Each table row in the Service Level Analysis table view contains summary information about a service class for the collection interval that falls within the reported time span. If the reported time span includes multiple collection intervals for a service class, each interval is reported separately. For each service class entry, the default analysis includes this data:
The Service Level Analysis workspace normally classifies a transaction into a single service class. You also have the ability to classify a CICS transaction into multiple service classes.
When you specify the SCLASS=ALL parameter on the Workload Manager start command, each transaction is matched against all of the available classification rules. The KC5_WLM_CLASSIFY parameter in PARMGEN is used to set this value.
Attempting to classify transactions into multiple service classes results in extra central processing unit (CPU) resource consumption. The amount of CPU usage is heavily dependant upon the number of service classes, the number and complexity of classification rules defined, and the number of CICS transactions to be classified. The activation of this feature merits careful consideration.
The Service Level Analysis table view displays data provided by the CICSplex Service Class Analysis attribute group.
