The Estimated MSU Consumption Rate Report analyzes HARCPU
data collected from non-z/OS workloads and calculates the max
MSU consumption rate, average MSU consumption rate, and the
MSU four-hour rolling average.
When analyzing HARCPU data at the detail level timespan, this
query calculates and reports the estimated maximum MSU
consumption rate, estimated average MSU consumption rate,
estimated MSU four-hour rolling average, and the CEC Capacity
In MSUs.
Note: At higher timespans you lose the ability to calculate a
MSU four-hour rolling average. Therefore, this element will
be dropped from the report.

ESTIMATED MSU CONSUMPTION RATE REPORT
To help you better understand the graphs and reports produced
by this query, definitions and calculations for the graphed
variables follow:
CEC The number of service units(expressed in
CAPACITY millions of service units per hour, MSUs)
IN MSUs: available to the partition, i.e. the LP CPU
capacity.
ESTIMATED Contains the four-hour rolling average number
AVERAGE MSU of service units consumed (expressed in MSU's)
CONSUMPTION by the partition during the CA MICS reporting
RATE: interval.
MSUPCBSY = (CPUNOCPU/PRSMNOPP)*(CPUPCBSY/100)*MODMSU
where: CPUNOCPU is the total dispatch time of all
processors assigned to the partition
PRSMNOPP is the physical CPU adjustment factor
used to convert CPU times to SU's
CPUPCBSY Pct Processor Busy
MODMSU is the CEC Capacity In MSUs
ESTIMATED Contains the maximum value of the four-hour
MAX. MSU rolling average number of service units consumed
CONSUMPTION (expressed in MSU's) by the partition, during
RATE: the CA MICS reporting interval.
MSUMXPBS = (CPUNOCPU/PRSMNOPP)*(CPUMXPBS/100)*MODMSU
where: CPUNOCPU The number of processors present in the
configuration (online or offline) at
the end of the measurement interval.
This represents only tightly-coupled
CPU's and has a value of 1 for a UP,
2 for MP/AP and dyadic, 4 for tetradic.
PRSMNOPP is the number of physical processors
assigned for use by PR/SM.
CPUMXPBS is the maximum percent busy for the
processors at any time during the
reporting interval.
MODMSU is the CEC Capacity In MSUs
