Disk Space (MSG)

Disk Space Management Summary Graph.
This graph is a measure of the average percent full of available capacity for the hard disk
assigned to the partition (or total system if there is no partitioning on the system).
Both internal and external disk assigned to the partition are consolidated into one measurement.
It does not differentiate between disk manufacturer and disk type.
The graph shows the current monthly average utilization, the color for the month and then shows
a 12-month projection based on up to 13 months prior history, if available. The color of a bar in a
certain month is the projected status of that resource for that month.
Color Percentage – Disk Space Usage
Green 74% or less used
Yellow 75% to 84% used
Red 85% or higher used
Green means the resource usage will be in the acceptable range. Yellow means the resource
usage is marginal and will need attention in the near future. Red means the resource usage is
critical and needs immediate attention.
These values are used because experience has shown they are the points at which typical
installations start to experience performance problems because of disk space constraint. A three-
month lead time is allowed to correct the situation.
