Processor Utilization by Hour
The Processor Utilization by Hour graph shows the hourly processor utilization average during the last 30-day
period. This allows you to see how the workload changes during a day.
•
The time indication, 08 for example, represents the time range 08:00 through 08:59.
• The black line shows the busiest hour of interactive peak utilization for that hour during the last 30-day
period, expressed as a percentage of the total processor capability assigned to the partition. It is likely that
when this value is high, degraded response times were experienced during that hour on at least one day of the
period.
• The blue line shows the busiest hour of total peak processor utilization for that hour during the last 30-day
period. It is likely that your system experienced a degradation of throughput some day during the period, if this
percentage is high during a longer period.
• The red line shows the interactive limit that is defined in your system, set by the interactive feature installed,
the IBM i software Edition or set by the partition definition.
