How SCRT Reports the 4 Hour Rolling Average?

The Detail LPAR Data (N5) section of the SCRT report shows the interval (date and hour) during the month for each LPAR on a CPC when the LPAR reached a maximum rolling 4-hour average utilization value (in MSUs). It also shows the interval in which the sum of all the LPARs reached a maximum rolling 4-hour average value. The SMF Recording interval varies from site to site based on the installation needs. The SCRT algorithm calculates 4HRA values at the hourly interval by taking an hourly average of 4HRA values at each of the LPAR SMF intervals. In the below example the SMF recording interval for LPAR A is 15 minutes and the peak reported in SCRT occurred at 20:00, so SCRT here has taken the mean of all the 4 intervals of 20th hour. 

LPAR Name	SMF interval	15 min interval SMF70LAC values	SCRT value reported in N5 section at 20th hour
A	20:00:00	53
A	20:15:00	53
A	20:30:00	52
A	20:45:00	50	Calculated value: AVG(20:00,20:15,20:30,20:45) 52 MSUs
