Hourly Peaks: on several of the graphs, the term Hourly Peak Max is used. This should be
interpreted the following way:

If the graph is an hourly graph of any type, the hourly peak is for the single worst hour

If the graph is a memory graph of any type, the hourly peak is always for the single worst
hour

If the graph is a daily graph (other than a memory graph), the hourly peak is an average of
the two peak hours

If the graph is a weekly or monthly graph, the hourly peak is always an average of the two
peak hours averaged during the shift for the period
Interactive Capacity Utilization on IBM i: This is a comparison of utilization for jobs coded i
(interactive) versus the total Interactive capacity of the server or partition (as defined by the
Interactive feature card, IBM i Edition or partition allocation).
System and Interactive on IBM i: This is a comparison of Interactive plus OS utilization versus
total processing capacity for the server or partition.
Total Utilization on IBM i: This is a ratio of the sum of utilization for IBM i plus the Interactive
utilization plus the Batch utilization versus the total processing capacity of the server or partition.
Total utilization on AIX: This is a ratio of the sum of the AIX operating system plus User jobs
utilization versus the total processing capacity for the server or partition.
