Working with combined MSU reduction data
When you generate a Monthly Summary Report for a month that contained mobile transactions or zCAP activity that was documented in either RMF or in CSV files, the report provides details about the MSU reduction values in the Combined MSU Reduction column. The report also provides links that enable you to drill down to levels where you can analyze your combined MSU reduction data to understand its impact on both the R4HA MSU utilizations and all MSU utilizations for each interval of the month.
In general, the value in the Combined MSU Reduction column can be:
- A number greater than 0, representing the actual combined mobile and/or zCAP reduction of peak 4HRA
- 0, indicating that the mobile or zCAP MSU usage does not contribute to the R4HA peak time interval for a given LPAR
- Blank, indicating that there is no mobile MSU or zCAP usage for a given LPAR for the whole month
The following figure shows a sample Monthly Summary Report that contains mobile transactions and zCAP activity:
Figure: Sample Monthly Summary Report with Combined MSU Reduction
The Combined MSU Reduction column contains the following data:
- The total combined MSU reduction for the MLC product at the R4HA peak
- The total combined MSU reduction for each CPC where the MLC product was running
Cost Analyzer determines the combined MSU reduction according to the rules defined in the IBM Mobile Workload Pricing and IBM z Systems Collocated Application Pricing announcements. When evaluating this report, note that the values in the R4HA First Peak (MSU) column already include the combined MSU reduction.
When you hover over any Combined MSU Reduction value for a CPC, a tooltip lists the following additional values:
- Combined MSU Total—The total number of combined MSUs for the MLC product family
- Combined MSU Reduction—The total number of MSUs subtracted from the peak R4HA value due to the mobile and zCAP activity
- Combined MSU Cost Reduction—The amount subtracted from the R4HA First Peak cost due to the mobile and zCAP activity
To drill-down to an MLC product's combined MSU reduction level and compare charts
- From the Monthly Summary Report, find the MLC product from the list and for any CPC that is running the product, and click the corresponding Combined MSU Reduction value hyperlink.
The Reporting Tool drills down to the MSU Utilization level for the MLC product running on the CPC:
Figure: Sample MLC Product Combined MSU Reduction level
The charting area displays the R4HA MSU Utilization chart for the selected MLC product. - In the Visibility column, select the box next to the LPAR name to add that LPAR's chart to the charting area.
The charting area displays the R4HA MSU Utilization chart for the selected LPAR as shown in the following figure:

When you select an LPAR to display in the charting area, the color-coded LPAR chart is added showing only the combined MSU reduction utilizations across the monthly intervals.
To assist in the analysis of the chart, you can perform any of the following actions:
- Using the toggle switch, show or hide the CPC R4HA curve.
- Perform the same interactive actions as described in Drill-down-levels.
- For any LPAR listed in the LPAR Name column, click its R4HA MSU Utilization preview chart.
The Reporting Tool drills down to a level that displays the monthly activity for the selected LPAR on its CPC as shown in the following figure:
Figure: Sample chart comparing average hourly MSUs to the R4HA
This level also enables you to compare the average hourly MSUs to the R4HA MSU Utilization by analyzing:
- The LPAR Monthly R4HA MSU Utilization chart
- A data grid that details each interval for the month and their corresponding MSU utilizations, including independent values for both mobile and zCAP activity
The following table describes the curves you can display in the charting area:
Chart curve | Description |
|---|---|
Average Hourly MSU | Average number of MSU utilized for the interval |
Actual LPAR R4HA MSU | Amount of R4HA utilization measured for the interval The value indicates the total R4HA MSU per hour. |
Adjusted LPAR R4HA MSU | Amount of R4HA utilization after applying the Combined Activity reduction The value indicates the reduced R4HA after applying the Combined Reduction to Measured LPAR R4HA. Depending on the LPAR, the combined reduction can consist of mobile transactions, zCAP activity, or both. |
LPAR R4HA Reduction Activity | Amount of Mobile Workload R4HA and/or zCAP R4HA utilization for the interval The different colors of the bar chart indicate values for the total number of R4HA MSUs identified as mobile transactions, and the total number of R4HA MSUs identified as zCAP activity. |
Defined Capacity | Displays or hides a background to contrast the charts against the LPAR Defined CapacityIf the Defined Capacity value is 0 MSUs, no background is displayed. |
To assist in the analysis of the chart, you can perform any of the following actions:
- Select which curves to display in the charting area
- Click on any number of intervals in the chart to mark them with an X and highlight the corresponding interval in the data grid
- Click on any number of intervals in the data grid to highlight these intervals in the data grid and mark the corresponding intervals in the chart with an X
- Click on Highlight top 5 LPAR R4HA intervals link to highlight the top 5 intervals in the data grid and mark them with an X in the chart
Click on Reset highlighted LPAR R4HA intervals to clear all highlighted intervals from the data grid and clear all X marks in the chartPerform the same interactive actions as described in Drill-down-levels
