How the peak four-hour rolling average MSU value is determined
z/OS Planning for Sub-Capacity Pricing
The peak interval is the highest utilization determined from the sum of the utilization for all LPARs in which a particular product ran in a given hour. It is not the sum of highest utilization for individual LPARs in which a particular product ran during different hours.
In this example, the peak interval for z/OS is in hour 2. The z/OS utilization value for the month is the sum of the z/OS utilizations in both LPARs during hour 2, or 135.
The peak interval for MQ Series and IMS is in hour 1. Since those products only run in LPAR 1, their utilization value for the month is the value for LPAR 1 in hour 1, or 60.
The peak interval for CICS and DB2 is in hour 2. Since those products only run in LPAR 2, their utilization value for the month is the value for LPAR 2 in hour 2, or 80.
