The trend projects the disk space utilization for the next three months.
The backward slash (dark green) area in the bottom of the graph of the last three trend
months shows the level of disk space utilization that is considered acceptable.
The crosshatch (yellow) area in the middle of the graph on the trend months shows the
level of disk space utilization that is considered marginal.
The forward slash (dark red) area at the top of the graph on the trend months shows the
level of disk space utilization that is considered critical.
The pink diamond on the trend months shows the calculated disk space utilization growth
based on the three last months' utilization.
The blue square shows the calculated disk space utilization based on the last six months'
utilization.
The yellow star shows the calculated disk space utilization based on the last 12 months'
utilization.
The recommended guidelines for the marginal and critical peak percentage are stated at the
bottom of the graph.
This graph also indicates the number of months before this partition reaches the guideline. If the
calculation is greater than 12 months, it is reported as 12 months.
You also see the change in stored data and maximum usage of disk space in percent during the
period.
