The trend projects the processor utilization for the next three months.

The backward slash (green) at the bottom of the three rightmost months (trend months)
shows the level of processor utilization that is considered acceptable.

The crosshatch (dark yellow) in the middle shows the level of processor utilization that is
considered marginal.

The forward slash (red) at the top shows the level of processor utilization that is
considered critical.

The pink diamond on the trend months shows the calculated peak processor utilization
based on the three last months' utilization.

The blue square shows the calculated peak processor utilization based on the last six
months utilization.

The yellow star shows the calculated peak processor utilization based on the last 12
months utilization.
The recommended guidelines for marginal and critical peak percentage for the different priorities
are shown in the Facts section at the bottom of the graph. It also indicates how many months to
go before this partition reaches the guideline.
The trend markers for the next three months show you how the processor utilization is predicted
to be if the load on the system is using the last three, six or twelve months of processor utilization
as representative of the trend. The trend is still calculated if less than 12 months of data is
available. However, the more data there is available, the more accurate the prediction is.
