Viewing the Delta in System Statistics

You can view the delta (relative change) in values between a saved set of statistics and the current set of statistics.

To view the delta in system statistics:

View the System Statistics page.

See "Viewing System Statistics" for instructions.
(Optional) Click Refresh Report until you see the set of statistics that you want to use a your "base" set for comparison.
Click Save Statistics.

The Show delta between current and saved values check box is automatically selected.
Do one of the following:
- Wait for some period of time, and then click Refresh Report.
- Navigate elsewhere in the Oracle Database XE graphical user interface, and then return to the System Statistics page.
For each individual statistic, the delta between the saved statistic and the current statistic is displayed.
