Working with the Job/STC Items report
The Job/STC Items report displays data that pertains to the contribution of each job to the R4HA peak in each of the 4 hours that comprise the query interval. Using the interactive features of the report, you can:
- Sort the column data to reorganize the list based on the column criteria
- Change the interval to recalculate the report and display the metrics of any 4-hour period
You can also perform Job/STC Operations. For more information see Performing-Job-STC-Operations-in-a-plan.
The following figure shows a sample Job/STC Items report:
The following table describes the data that each column of the report contains:
Column header | Description |
|---|---|
Job/STC Name | Job name and its Job Entry System (JES) number |
LPAR Name | Name of the LPAR |
Workload Name | Name of the workload that contains the job |
Peak R4HA Contribution | 4-hour period that determined the R4HA peak value This section of the report provides columns that list the date and times of the each of the four hours that comprise the peak interval. For each job in the list, the column data displays the individual MSU contribution to the peak R4HA. The blue segment of each hour provides a visual aide to identify the relative value of the metric. The size of the blue segment is based on the highest hourly value in the list. The blue segment for each hour is a graphic representation of the ratio between the hourly value for the job and the highest value. The four individual hours that are displayed represent the hours that were used to calculate the R4HA peak. In general for all metrics, the peak hour column is the last date and time. The other 3 hours are the hours that preceded the peak hour and thus contributed to the calculation of the R4HA. |
Contribution to Peak | Total amount of MSUs that the job contributed to the peak R4HA |
Starting Date/Time | Starting date and time of the job |
Suite Name | Name of the user-defined group of jobs and STC |
Service Class | Name of the Service Class for the job |
Report Class | Name of the Report Class for the job |
For each of the four hours that comprise the peak interval, you can select which metrics you want to display in the report. The following table describes the metrics that can be displayed:
Metric type | Description |
|---|---|
Peak R4HA Contribution (MSUs) | Number of Millions of Service Units (MSUs) that the activity of the job in the current hour contributed to peak R4HA This value is calculated as: 0.25 * (MSUs used by the Job in the current hour) |
CPU Seconds | General Purpose Processor seconds used by the Job in the current hour |
MSU Used | General Purpose Processor MSUs used by the Job during the current hour This value is calculated as: (CPU second used) * (Software Service Units coefficient) / 1000000 |
Cost Contribution | Contribution of Job's activity in the current hour to the cost of all products that have Peak R4HA in the selected interval This value is calculated as: (Average Cost per MSU of all such Products) * (Job Peak R4HA contribution) |
zIIP Eligible seconds | CPU seconds used on the General Purpose Processor that are eligible to be used on zIIP processor |
zIIP seconds | zIIP seconds used by the Job in the current hour |
The report also provides a visual cue to indicate whether a job was processing during the hour before or after the 4 hour peak interval. A job-in-progress arrow 
that is displayed after a metric indicates that the job continued into the next hour. Similarly, a job-in-progress arrow 
that is displayed before a metric indicates that the job was processing in the previous hour.
The report has interactive and dynamic features to assist in your analysis of the report data. Use the following procedures to examine the report:
To sort the report data by the column values
Click any column header.
Cost Management sorts the data based on the selected column and displays the results. The column header displays 
to indicate that the report is sorted by this column's values.
To change the interval of the report
The Job/STC Report uses the peak interval as a default and displays data based on the hour when the peak value occurred and the 3 hours that preceded it. You can change this interval and recalculate the report to display metrics from any four-hour period that occurred in the month.
From the Job/STC Report, click Change Interval.The report displays a chart of the MSU utilization activity for the month and indicates the peak with an X and the R4HA Window with a red highlight as shown in the following sample figure:
Hover over the chart and click the date and hour you want to set as the final hour of the interval.Cost Management recalculates the metrics based on the selected interval, and then displays the results. The following table describes additional actions you can perform to assist in the analysis of the chart:
Analysis action
Steps
Zoom in on an area of the chart
Click and drag between any two points on the chart to zoom in on the selected area.
To assist in the analysis of the zoom view, you can:- View the entire monthly chart, which is highlighted as a histogram at the top of the charting area
- Adjust the selected area by using the slider controls
Identify points on the chart with the date and hour they occurred
Hover the mouse over any point on the chart to view the date and hour it occurred.
Restore the charting area view to show the chart for the entire month
Click Show All.
After viewing the results of the interval change, click Close Chart.
To filter Workloads from the query result set
- From the Job/STC Report, click Filter Workloads.
The Filter Workload dialog box is displayed.
- Uncheck the Workloads that you want to remove, click Apply Filters.
The filter is applied to the Job/STC report.
To export the report to a CSV file
From the Job/STC Report, click Export to CSV.The CSV file is exported to the browser.
