Disk Usage Summary
When you open the Disk Usage Summary report,
you see a single graph. The report lists the databases over a period
when the data collector was gathered. This allows you to see how the
sizes of the databases are changing over time. Figure 13 shows the Disk Usage Summary report.
Figure 13. Disk Usage Summary report
As you can see, the information is laid out
between the data files, shown as the database sizes, and the
transaction log, shown as the log sizes. Each one shows a starting size
and the current size, which allows you to see a trend. Running this
report once a week or once a month will quickly let you know which
databases or logs you need to keep an eye on for explosive growth.
You can click the database name to open a new report, the Disk Usage for Database report, as shown in Figure 14.
Figure 14. Disk Usage for Database report
The Disk Usage for Database report details how
much of the space allocated to the database is being used and how much
is free. It also shows whether the space used is taken up by indexes or
data.
