Performance Summary Report
The Performance Summary Report summarizes key measures in the system so that potential trouble spots can be located.
The Performance Summary Report is produced by using the PERFSUM and PERFORM Analyzer control statements. The data for this report is obtained by using the following Extractor control statements:
- ASMDATA
- CHANNEL
- CPU
- DEVICE
- ENQUEUE
- EXTSUM
- IOQ
- PAGING
- TSODATA
- WORKLOAD
The Performance Summary Report report (Figure) is divided into the following sections:
Bottleneck Detection
This section lists and describes bottlenecks detected in key system areas. The types of bottlenecks can be defined by you in the PERFSUM control statement. If you do not define bottleneck types in the PERFSUM control statement, defaults are used.
Three dashes (---) in the DETECTED column indicate that the data necessary to determine if this bottleneck existed is not available. This situation is most likely due to missing record types on which this determination is based.
Performance Measures Summary
This section lists busy times and queue depths for key areas of the system.
Job Class Activity
This section lists active and completed jobs for the extracted time frame.
Policy Activations
This section lists the service policies that were active during the time frame for this report. The list includes the policy name, its description, and the date and time it was activated.
Workload Activity
This section lists service classes and report classes, displaying their performance index, response time, transactions, and service units.
The Performance Summary Report is shown in the following figure.
