Reduce MLC Using Peak 4HRA / R4HA

Insights into Peak 4HRA Data in SCRT with IntelliMagic Vision

IntelliMagic Vision provides visibility into peak 4HRA data far beyond what is provided by IBM’s Sub-Capacity Reporting Tool (SCRT) to enable you to reduce MLC expense.

View the following video for an example of that visibility.

MSUs over Time

This graphical view displays SCRT MSU values by product over the selected time interval, which will commonly be a billing month. From this view several data items that aid SCRT analysis are immediately apparent, including monthly peak values by product, when they occurred, how much higher the peak was than other time intervals, and the relative relationships between MSU consumption of different products.

Peak MSUs (table)

The previously described information is also available in a tabular format. In addition to the peak MSU consumption for the billing month, this initial view also identifies the interval when the peak occurred, and whether soft or group capping was in effect during that peak interval.

There are separate tables reflecting the distinct values for Country Multiplex Pricing (CMP), shown here, and legacy SCRT with separate peak intervals by CEC.

CPU Use during Peak 4HRA Interval

One common line of inquiry for SCRT analysis is to understand the workload that was executing during the peak interval, so that any opportunities to reschedule work outside of non-peak intervals can be identified. From the graphical view the “MSUs at Time” drilldown takes you directly into a view of the CPU consumption during the selected 4-hour interval.  From there all the powerful CPU analysis capabilities of IntelliMagic Vision are available, to further drilldown by system, by workload, by WLM importance level, by service class, by report class, and ultimately by address space.

Drilldown to CPU Use by Address Space

As suggested in “Drilldown to CPU Use by WLM Importance,” this drilldown allows you to see the specific address spaces classified by WLM as discretionary that were executing and thus contributing toward the four-hour rolling average value during that interval.

Time-of-day Profile of Product MSUs by Date

Another of IntelliMagic Vision’s powerful analytical capabilities particularly valuable for SCRT analysis is the “By Date” drilldown. This also provides a time of day profile over the selected interval, but in this case each day is represented by a separate line. This view visualizes how much higher the peak value was than the next set of highest peak values and when they occurred, both by date and by time of day.
