This graph provides a summary view of the relative CPU and I/O
usage for the system. Users may choose to view daily or weekly
summaries of this information and may choose to view CPU only,
I/O only or both on the same axis.
CPU usage is determined by measuring the number of integer calculations
that can be performed per second and then comparing the calculated
value to the highest result for the day or week.
I/O usage is determined by measuring the number of disk reads
per second and then comparing the calculated value to the highest
result for the day or week.
For both CPU and I/O usage, a graph value of zero is used when
the utilization of the system is at its lowest point for the day
or week.
By clicking the right mouse button on a selected point of the
daily graph, the user may also display the tabular data for the
specified period.
