The latest release of EasySMF adds a new report: Workload Manager – Service Class Overview. This report gives information about all the service classes in the sysplex in a single report. It shows goals, activity and delays for each service class period. The report is particularly useful if you are not familiar with the WLM policy on a system, because you can see at a glance the goals and importances as well as the amount of work in each service class period.
For a more detailed look at the report, see the Report Spotlight in this issue.
Many of the changes in the new release were concentrated on improving Workload Manager and Sysplex reporting. The WLM reports can now be viewed by sysplex or individual system. The Workload Manager – Service Class Detail report now shows the performance index for the sysplex and each system in the sysplex. A new chart shows the response time for the service class period.
The type 30 Job Completions reports and Job Status During Interval report now support filtering by sysplex and service class, to complement the Workload Manager reports. From the Service Class Detail report you can select the Job Status During Interval report to see the work running in that service class during the interval, or select one of the Job Completions reports to see the jobs that ended in the service class.
Copying to the clipboard is now available in the reports, allowing Copy and Paste to other applications e.g. Microsoft Word.
Individual charts can be copied by right clicking on the chart and selecting “Copy to Clipboard”. The menu option Edit->Copy or Control-C will copy all the charts in the current report to the clipboard as a single image.
Data from the tabular reports can also be copied and pasted – either the entire report or if rows are selected, specific rows.
z/OS 1.13 added response time distribution information to type 72 records for service classes with velocity goals. Charting the response time distribution for velocity goals is not as simple as response time goals, because the velocity response time “buckets” are not fixed values. A new chart design is needed for the velocity goals.
Type 72 data from some z/OS 1.13 systems with real workloads would be very useful for developing these reports. If you can help, please contact email@example.com or reply to this email.
The Workload Manager – Service Class Overview report shows you information about all the service classes in a single report.
The report helps you understand the WLM policy in use by showing not only the service classes, goals and importances, but also the amount of work and the delays for each service class period.
Selecting “Active Service Classes Only” is a quick way to see the number of active service class periods in the system.
Information in the report includes:
- Service class description
- Duration of service class periods
- Performance Index (calculated over the selected time interval)
- CPU critical and storage critical attributes
- Number of transactions
- Average response and standard deviation
- Amount of service consumed
- Resource group information
Each column is sortable, so you can click on the column header to sort by Importance, Performance Index, Velocity, Service etc.
The report serves as an index for the Service Class Detail report. Clicking on an entry for a service class will take you to the Service Class Detail report for that service class, where you can view more information about the service class during the time interval.
